This course covers the key aspects of current instrumentation and process control technology and is designed to enable maintenance personnel to carry out commissioning, calibration and maintenance of the typical devices used for measurement and control in industrial systems.



The course is ideal for those who presently possess some electrical knowledge, work in a maintenance environment and seek to expand their activities to include process control and instrumentation systems.



The course is extensively ‘hands on’, giving participants considerable practical experience of the devices typically found in industry. Comprehensive course notes are provided.



On completion of the course, participants will be able to

· appreciate the operation of typical instrumentation systems

· identify the various methods of signal transmission

· correctly connect electrical or air-powered devices

understand the equipment used in

 -current loops (process meters, transmitters, chart recorders)

-temperature measurement (RTDs, thermocouples, etc)

-pressure measurement (bourdon gauges, air and electrical dp cells)

-level measurement (bubblers, pressure cells, ultrasonic, load cells)

-flow measurement (orifice plates, mag-flow meters, mass-flow meters, etc)

-output devices (flow control valves, valve positioner, I to P converters)

· correctly use a range of industrial calibration equipment (current sources, thermocouple and RTD simulators, digital pressure indicator/calibrators)

· correctly connect, commission and calibrate current loop devices, temperature transmitters, pressure switches, pressure sensors, dp cells, I to P converters and HART devices and  understand the principles of pH measurement.


What do candidates on the instrumentation course actually do?

The instrumentation course involves an extensive understanding of current loops and the devices typically found on them. Participants look in detail at the devices used to measure temperature, pressure, level and flow, and briefly at control valves and pH.

The course notes are quite extensive and explain how the various devices are used, without getting involved in the underlying theory. For example, we would look in detail at what signals a thermocouple produces, but only very briefly at how it works. Some sample pages from the course notes give an indication of this approach,  what industrial temperature sensors and transmitters actually look like, the use of dp cells, how hydrostatic pressure measurements are converted to level measurements using pressure sensors and how manifolds are used to zero dp cells used in flow metering:

The course involves connecting various devices into current loops so that candidates learn about how current loops work and how devices are connected into them. They also calibrate these devices using a range of professional industrial  current calibrators, used throughout the instrumentation engineering world.

Participants will be taught how to connect up a range of industry-standard loop indicators, looking at the various configuration options and adjusting them so that they indicate the required PV at the zero and span settings.

Participants on the instrumentation course then learn about the various devices used in industrial temperature measurement systems - we concentrate on thermocouples and Pt100s and their associated cabling, connectors and transmitter heads. Candidates connect up various sensors, looking at the signals that they produce and build current loops around the relevant transmitters.

The circuits built by candidates are then calibrated using industrial temperature calibration units. Participants learn about issues like cold junction compensation and three/four wire measurements.

Candidates then learn about pressure measurement: the various units used to quantify pressure and how industrial pressure measurement devices should be calibrated, using industrial pressure sources.

For further practice at using the pressure sources, candidates on the instrumentation course then connect and calibrate a range of industrial pressure switches.

Candidates then learn about level measurement systems and the various methods by which industrial measurements are made are analysed; we look at hydrostatic, load cell and bubbler systems. Ultrasonic measurement systems are quite common and are therefore the main focus of the instrumentation course.

Many instrumentation systems control processes using valves and we therefore look at the various types of control valves, I to P converters and valve positioners commonly used and how these would be connected and calibrated

pH measurement are used in some industries, and we therefore look at how pH meter controller works, giving candidates the opportunity to concentrate on them if they are relevant to their workplace. A stock of calibration and buffer fluids are used to create a range of readings for each measurement.

. All the tools needed by the candidates to make the electrical and pneumatic connections to the devices involved in the practical exercises are provided by us.






Whether you are involved in testing laboratory or inspection area or into calibrating physical inspection areas, this course is for you!

 “Learn the practical approach to measuring uncertainty.”

 Understand the steps required and the accepted practices needed for  accredited laboratories.

This course is intended for anyone taking measurements or responsible for maintaining quality including new hires, inspection personnel, and management, or as a refresher for experienced technicians.     


ISO QMS does not require calibration to be performed by accredited laboratory except ISO 17025 and TS 16949, so to save on  cost, some quality   practitioners  conduct instead  internal calibration.


But a few  questions usually  surface on this practice: Is the calibration procedure acceptable?  Is the staff performing calibration competent? Is there any measurement uncertainty evaluation? Is there any analysis of the calibration whether the equipment is fit for purpose? This training module can answer all the questions above and without doubt it has helped many organizations in cost saving activities and at the same time there is no worry of acceptance.
