Various Kinds and Types of a Torque Calibrator

The torque calibrator comes equipped with two beams, both having a hydraulic cylinder, which is used for the exerting of forces that appear on opposite ends of the beams, as well as load cells that can be found mounted on opposite sides of the beams that are used for the measuring of force that is applied to the beams. These beams were specifically designed to have a cell mounted between them, which can then calibrate the required amount of distance and force that is needed. A torque calibrator is available to the customer in many different types, and can also be called pressure calibration equipment, that has to use the HP 6920B meter for measurements.

The torque calibrator was used to measure up to two thousand pounds worth of torque in both clockwise modes, and counter clockwise modes in the past. Periodic calibration is what you will need to perform in order to maintain these instruments.

Dry-block calibrators, which are made to your specific requirements by Utica, are one of many various types of calibration instruments available. These machines are extremely versatile for when it comes to the calibrating of temperature sensor assemblies. These instruments are portable, traceable and can easily meet the calibration requirements in the field temperature work areas, but they can also cause many calibration errors if they are not understood or monitored correctly and properly. Every dry-block calibrator comes with a heated block which is designed to have several interchangeable inserts. There will be a sensor that is located inside the block for measuring and controlling temperature, but it is not placed within the insert. A thermocouple is made when insert and block materials that are selected to form a thermocouple are used, therefore causing small differences, and sometimes errors as well, to be introduced.

The torque wrench is another well-known type of calibrator. This is an item that is used to accurately apply a specific amount of force to a fastener which can either be a nut or a bolt. It is very similar to that of the socket wrench, but it has more special internal mechanisms. This special wrench is used primarily for when the tightening of screws and bolts is desperately needed, as well as to prevent bolt tension from occurring. The next instrument, is the electric driver, which provides stability, dependence and repeatability, when stopping bolt tension as well as for low to mid-range applications. By having a special grip, it reduces stress from long working hours and ensures safety as it is designed for a direct current flow, low tension method. Lastly is the air tool calibrator, which has been said by Utica to be the foundation of just about any fastening strategy. Air tool calibrators come in many different types, which use compressed air as well as calibration meters, such as the HP 6920B meter to operate adequately. These have the same setup as the electric driver and wrench calibrators, but need more maintenance, for if they are not given enough, the precise calibrations you are after will not be accurate, which will lead to errors.

Calibration Of Electrical Test Equipment

Maintaining and ensuring your test equipment is properly calibrated is essential if you are to obtain good and usable results from your experiments. Test equipment machines are only as good as the results they provide and if your machine is poorly maintained and inaccurate then obviously so will your conclusions be.

When you first purchase a brand new piece of testing equipment it should normally arrive with a certificate confirming that it was calibrated before leaving the manufacturers. Throughout the life of the apparatus it is important to have it regularly serviced and maintained and most importantly calibrated. The certificate that comes with re-calibration is your proof of a well-maintained machine and this will work in your favour when qualifying your test results.

A calibration certificate is also useful should you wish to sell any piece of machinery. You are more likely to get a good price if you are able to provide an audit trail, which proves that your equipment has been well looked after and cared for, and that its reliability can be confirmed.

Along with proof of calibration for quality audits and proof that your apparatus meets nationally accepted requirements it will also show the level and professionalism to which it has been calibrated.

When checking on the calibration certificate for a particular machine, especially if you are buying a used or second-hand model, make sure it has the following information: The correct instrument identification number, environmental conditions at the time of calibration, proof that the tests were conducted to a high standard and that there is an auditable, paper trail for the particular machine.

Quite often used models are sold as seen and you will have to pay an additional cost for calibration to be undertaken. Should you require this additional service, make sure you have the correct documentation afterwards.

You can also request a calibration certificate with data. While most certificates confirm the working parameters you may wish to have a copy of the actual data modes and ranges that the machine was tested against. Although tests conducted with data provided give you an accurate indication of the machine's capabilities, the extra information does also tend to cost that little bit extra.

Remember, whether you are buying a brand new test appliance or a second-hand one, or if you are perhaps leasing it, always check to make sure the equipment has been accurately calibrated to produce the desired information you are looking for.

The Importance of Calibration Services

For any type of equipment from testing and monitoring to your home electricity and natural gas meters, regular calibration services are extremely important in order to gauge the accuracy of the instrumentation in use. Most large industrial companies make a point of engaging regular calibration service groups to insure that all of their equipment and instrumentation is working accurately, according to manufacturer's specifications. In industry, this accuracy is crucial to maintaining regular process operations and to avoid running afoul of local, regional and federal compliance laws. Instrumentation of any type that calculates usage should be regularly checked by professional calibration services.

Instrumentation

Instrumentation is generally very delicately balanced to meet specification and use standards. As an example, air and pressure meters are types of instrumentation that help maintain certain handling systems. If this instrumentation is not regularly calibrated, the system may begin to register inaccurate volumes at inputs and outputs. In the case of liquid flow meters, inaccurate calibration data may cause too high or too low a level of flow of liquid into a system which further damages the equipment and causes costly repairs and inefficient overall process operations. This is also true of pressure and release valves that are metered. Monitoring equipment and instrumentation calibrations over long periods of time can also help determine flaws in a system or in the compatibility of the instrumentation with the particular type of industrial equipment in use. Most large industrial companies see the cost-effectiveness in maintaining records of all calibrations performed. If equipment or instrumentation requires an unusual number of calibrations, this can be an indication of problems with the metering devices or changes made to a process.

Calibration - How It's Done

Calibration is a relatively simple service, depending on the nature of the equipment, process and instrumentation involved. Professional calibration services rely on their own calibration instrumentation and knowledge of calculations as approved by a certifying, licensed compliance bureau which insures the accuracy of all equipment and instrumentation. Professional instrumentation used by calibration services is also checked for accuracy under regulated conditions so that it meets with compliance bureau guidelines. Postage meters are an example of equipment that fall under the US Postal laws and require all businesses using these meters to be calibrated once a year. Professional calibration services inspect equipment or instrumentation, insuring it is in operable condition and then proceed with testing that results in compliant ranges of operation. A basic report, depending on the complexity of the instrumentation or equipment involved, is issued for owner's review. If there are any problems, these professionals will discuss issues or potential for future inaccuracies.

The Electrical Learning Journey

The following are a sampling of some of the journey level electrical courses one can take to advance his or her learning in his or her chosen electrical field.

The first, an eight hour training session in Leviton, teaches students about the installation of cable, about its use and termination and about how to install and handle a multiple pair. They learn as well about installing a twisted pair, as well as fibre optic and coax cables. This is one of the electrical courses in the UK that offers continuing education credits towards electrician license renewal. Six credits are awarded with successful completion of this course.

For certification in various elements of electrical course there are a number of UK electrical courses available. The first is that for the certification in residential general electrician and life and fire safety. The instructors in these electrical courses look at the various principles of the federal National Electrical Code of 1999, Ohms law and the basic principles that must be adhered to and learned for certification. Students are able to participate in practice tests. To attend these certification electrical courses each student must bring his or her own copy of the NEC book. These electrical courses are available as classroom lectures during the day or online for those who cant attend the lectures.

Electrical Test Instruments, LLC - Circuit Breaker Test Set Calibration

One of the more introductory of the electrical courses for journey level electricians is the instrumentation intro class. An introduction into industrial instrumentation, the course teaches flow, pressure, temperature and monitoring of all these levels as part of working in process control. The nine week course teaches students who are just starting out in the instrumentation field as well as those who want to bone up on the lessons of instrumentation for their ISA exam to become a certified control systems technician.

Three follow up electrical courses expand the instrumentation lessons. Instrumentation 102 is nine weeks too, and in this session students work in a laboratory environment applying the classroom lessons learned in the introductory courses. They learn calibration techniques and methods, and more closer examine the fundamentals and operations of indicators, switches, recorders and transmitters. This course is ideal for loop check workers and those involved in the installation of instrumentation equipment.

Electrical Test Instruments, LLC - Circuit Breaker Tester Calibration

This course is then followed by a chance to learn about why process control systems are important, and why control logic is crucial to every industry. Every student in this class will have to apply prior knowledge in the electrical laboratory. They'll use electrical equipment to calibrate, wire and test it under the watchful eye of the trained instructor. They'll construct their own process system, demonstrating safe procedures for start-up and tuning. This training is one of the electrical courses that teach and hone troubleshooting capabilities and apply the knowledge they've learned about maintaining electrical instruments.

The final one of the instrumentation electrical courses refines the former training and looks at advanced instrumentation practices. In addition, students will learn about MMI and computer graphics and how important they have become in electrical instrumentation.

The Importance of Preventive Electrical Equipment Maintenance

When your business depends on electrical machinery and equipment for increased productivity and improved cash flow, it is extremely important to keep that machinery inspected and well-maintained on a regular basis. Preventive electrical equipment maintenance done regularly by trained, professional and experienced electrical workers helps to detect electrical problems before they become serious issues. By scheduling routine maintenance checks that utilize advanced technology and expert electrical skills, the industrial equipment and machinery on which your business runs can continue working efficiently, reducing the risk of a catastrophic failure that can cost time and money. Read on to learn the benefits of preventive electrical equipment maintenance, as well as the use of infrared thermography in detecting electrical problems.

Save Time and Money:

An effective preventive electrical maintenance program involves scheduling routine inspections and checkups on a regular basis, ensuring that your equipment and machinery is continually checked for both minor and major problems. Even small electrical problems can become more severe issues if left undetected for too long, which can lead to emergency repairs that require halted production lines and costly replacement parts. In a challenging global economy that demands cost-effective mass production on a timely basis, stopping production due to equipment failure can have major setbacks.

A Safer Workplace:

Not only can preventive electrical maintenance save businesses time and money, but by keeping equipment functioning properly, the risk of hazard is greatly reduced and the work environment becomes a safer place. Electrical equipment failure can lead to serious hazards, including fires and arc flash, which can leave workers severely injured. Equipment that is not working properly or problems that are left undetected can have unfortunate results for electricians working with or near the equipment. Machinery should be inspected frequently to identify potential problems and prevent them from becoming dangers in the workplace.

Using Infrared Thermography:

The use of infrared (IR) thermography is critical to preventive maintenance in electrical work environments. All objects radiate thermal energy, or heat, and IR cameras can detect the radiation of heat that is emitted from any given object by taking "heat" images. Through a range of colors, these images present hot spots that cannot otherwise be perceived by the naked eye. IR thermography is used to reveal loose circuits, equipment failure and safety hazards. Electrical workers can then use the thermographic images to analyze and measure temperatures, identifying problems and fixing them before they become severe.

Electrical Machine Repair

Electrical machine is a device that uses electricity as its primary source of energy. This is an electronic device that converts mechanical energy to electrical energy one way or another.

The components of an electrical device are complex. Therefore, each component should be taken care of, because any damage on one of its parts could affect the overall functionality. Electric machine repair is quite costly, and there is no assurance that all damaged devices can be repaired by technicians. The results of repair always rely on the extent of damage. The bigger the damage is, the lesser possibility that a device can be returned into its normal status.

Repairing electrical motors need enormous knowledge and skills regarding the concepts of electro-mechanical. The electric current should be tested in every repair as any shortages in the current level of the machine can cause accidental problems, which further damage the device, and even cause electrical grounds.

Electrical Test Instruments, LLC - Electrical Calibration

The three parts of electrical machines are generator, motor, and transformer. A generator is a common device that converts mechanical energy to constant electrical energy. The two types of generator are AC generator and DC generator. While motor has also two types, which is AC motor and DC motor. The last part of electric machines is transformer, which converts alternating current from lower to higher level. The functions of transformer are based on the concept of mutual induction.

Having knowledge regarding the different components of electrical motors can make you aware on the functions of your own equipments. And, if there are any problems on your devices, you are capable to make judgments if you need to call electric machine repairs, or you can repair your devices all by yourself since you already have knowledge in electro-mechanical concepts. With your knowledge, you can gauge your capacities in discovering and managing any machinery defects.

Electrical Test Instruments, LLC - Electric Equipment Repair And Calibration

Electric motors are crucial to production. So it is important that service and maintenance is working professional. To get top service and great results in this industry, you must first learn the "ins and out" of the service business especially for electro-mechanicalengineering.

Electric Motor Repair Can Mean Small Or Big Repairs

In the world today there are many different electric motors. We all see equipment that is powered by motors, whether you realize it or not. It might be a pool pump that powers water through a swimming pool, to a lathe in a woodshop that is used to make bowls or pencils. These motors typically average in size to about 5 HP. Then there are the larger electric motors that are used like vehicle motors, airplane motors. And you'll hear of electric motors commonly used in business today that are commercial and industrial electric motors like those you might find in factories or warehouses and are used to power large machines. Electric motors are a big part of how businesses and factories are powered, but like everything today, there will be times when something goes wrong and you will need to have parts repaired or replaced on the motor.

Electrical Test Instruments, LLC - Electrical Calibration Services

Electric motor repairs usually need to be done by qualified repairmen or companies that specialize in electric motor repair. If you have an electric motor that is especially large and heavy, you will need to verify with the repair shop that they have the necessary equipment, like cranes, to be able to move your motor.

When your pool pump motor runs dry and burns up you know you can call your pool technician and he will repair the problem for you or if you need an electric motor repaired on any of your woodworking machines, you generally call in a repairman who works on small machines. When larger more powerful motors develop problems and need parts and repair work it often entails a larger scaled motor repair division found in companies that special in industrial and commercial machine motors.

These companies tend to have repairmen and technicians who are skilled in working on both A/C motors and D/C motors as well as motors that have a higher horse power. They will also have all the necessary tools and equipment needed to repair your motor back to a pristine state. Many of the large scale electric motor repair shops will have the ability to put a high build epoxy varnish treatment on repaired items as well as to do a Core Loss test, and equipment that can do vibrations testing on the electric motors and parts repaired.

At times your motor will have become so damaged, often because of too much heat that damages the insulation or because the winding has been cut, that it will need to be rewound. Almost all electric motor repair shops have the equipment required to test for this and can offer you motor rewinding services. Most shops should be experienced enough to be able to rewind all types and sizes of motors, such as for both A/C and D/C motors. With any electric motor repair work done, make sure to check is the shop is a certified warranty repair facility for your type engine manufacturer. If your machine is still under warranty, it is going to be very important that you use a shop that can do certified repair work on your engine.

When Should You Think of AC Repair or Maintenance Services?

In a world where technology allows supreme comfort and convenience in every season, ACs have become a core part of our everyday life.

However, this important asset can be easily left in bad condition if proper and prompt attention is not given to its timely and well-rounded maintenance.

There is no way one can be caught off guard in a wrong weather as an AC conks off. To avoid such situations, remember to:

1. Pay heed to small signs that call notice for quick AC maintenance services. This entails annual tune-ups, timely optimization for a particular weather change, damage cracks fix-up, odd sounds, outdoor unit's unfamiliar look, skewed airflow, leaks or other duct-related issues.

2. Loose fittings should not be taken lightly and AC repair companies should be alerted in time.

3. Opt for an AC maintenance service that does timely checks for thermostats, ducts, batteries, refrigerants etc.

4. It is advisable to ensure clean filters, ducts before the summer sets in. AC maintenance services can also take care of dirt-clean-ups and airflow checks.

5. AC maintenance companies should also provide lubrication and equipment optimization advice.

6. Look for service providers who can optimize and increase the life-cycle of the equipment.

7. Keep monitoring the AC throughout summers for performance snags and call AC repair companies if something goes awry. Take cognizance of load circulation and air quality along with basic cooling during maintenance.

8. It is better to have a look at the manual for automatic settings once in a while for avoiding over-runs. Make time for maintenance for areas like battery and thermostat from time to time.

9. Preventive AC maintenance is always better than reactive AC repair.

As a general rule you have to replace your air conditioning filters or clean reusable filters at least four times in a year and more frequently during high usage period. AC filters provide a range of values. It is as per the price you pay. So ensure to buy the one which provides many benefits that your money can buy.

The following are some of the AC filter options usually available in the market.

1. Fiberglass filters: These are cost effective and can help in blocking large dust particles.

2. Electrostatic filters: They are washable and their static charge attracts dust, dirt and other matters.

3. Pleated filters: These trap and eliminate large allergens like pollen and mold.

4. Electronic air cleaners: These create an ionized electrical field to eliminate almost all pollen and mold.

To ensure you regularly tune-up your AC, inspect the following;

Coolant levels and pressure

Calibrate thermostat and cycle & temperature

Wiring, contacts, capacitors and relays

Evaporator coil and condensate drain are clean and clear.

Condenser fan motor and blades;

Compressor amps during the startup phase

Once you make room for some basic points at proper intervals of time, hire the right AC repair companies and plan for appropriate AC maintenance services. Your AC assets will continue to serve you as per your expectations and to the optimal satisfaction across a reasonable lifecycle. Assets can always malfunction but they always give small signs that when properly attended, make maintenance and repair of ACs a fruitful and rewarding exercise. Choose AC maintenance services wisely and contribute your bit in keeping the AC running well and long.

Professional Calibration Services For The Home

Although most homeowners overlook the importance of their own metering systems, this can be very costly in the long run. Water, electricity and natural gas meters should be inspected and calibrated at least once every two to three years. One reason is the volume of meter use. Another reason is over billing if these meters prove inaccurate.

How to Choose an Electric Motor Repair Company

To ensure smooth functioning of your factory/warehouse, it's important that the electric motors work effectively. Electric motor repairs are more often than not, a result of production activities and the factory environment. However they can also be a result of inadequate and substandard work by an electric motor repair company. To ensure that factory operates smoothly, here are a few tips to be followed:

- The first and foremost consideration is to check if the company is clean and maintained in an orderly fashion. Nothing equals the benefits of a well experienced and trained professional who follows the required procedures to the T.

- All certified electric motor repair companies ensure that their equipments and other instruments are calibrated annually with standard ANSI or the American National Standards Institute. Thus, with state of the art equipments and instruments, you can be assured that your motor is in safe hands. Accuracy of the reading is ensured through the calibration.

- Documentation is a very important aspect when it comes to repairing motors. Although the skill of the professional is important to ensure a smooth process, well established electric motor companies don't always rely on the professional; they prefer to rather rely on documents. Thus whenever a repair is carried out, a detailed document is prepared to explain in detail the different procedures undertaken. Thus, you are assured that the work is being carried out in accordance with requirements set by EASA.

- Even before the repair or rewinding work is begun, professionals spend considerable time and energy in determining the cause of the problem. Thus the motor is tested through detailed procedures including core loss testing and hot spot testing.

- Certification is an important consideration. These are issued after thorough scrutiny and adherence to strict standards. An accreditation to EASA or the Electric Apparatus Service Association is always a good indicator of the competency of the electric motor repair company. The norms for acceptance in these associations are very strict. For instance, EASA requires their members to environmentally conscious at all times.

The company that you would choose ensures that they test run the motor for problems and check the vibration base line, with the problems being recorded. The motor is then disassembled, cleaned, and inspected. When doing so, possible electrical and mechanical problems are assessed and repaired. The motor is then hydro-cleaned, baked dry, and varnished with insulated varnish.

As earlier said, finding a competent electric motor company is essential to ensure a smooth flow of your company.
