Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Acquiring Temperatures of DUT and TU in LabView
Voltage vs. temperature of RTD sensors for the DUT and TU is measured, and calibrated, and was successfully acquired in LabView
The temperature read in out LabView program is same as in ADaq (a provided software that reads the temperature from RTD sensor)
Instruments Control system (LabView programs)
Pump Control
LabView program is developed to control the pump
Temperature inputs were read and compared with temperature from Adaq. But the pump is not setup to use yet
DUT power management
LabView software is ready to use.
Its hasn’t been hookedup with DUT yet.
Overflow circuit breaker
LabView is developed and tested
Accomplishments from Previous Week
Ta and Th were calibrated. A perfect linear relationship between the voltage read in DAQ 6009 and Temperature read in Adaq was found.
- Peristaltic Pump has arrived and check if it works.
- Wire tapped the Temperature Sensing Board (TSB) for Th and Ta
Goals for Next Week (list names after each item). Use specific and measurable objectives.
- Acquire/Purchase all the materials needed.
- Finish assembling the water system
- System testing, calibrations
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
- In order to acquire temperature measurements of TU and DUT, tap the wire that leads off from Temperature Sensing Board (TSB). Jim gave a circuit diagram of the TSB board.
- If there still seems to be a problem with PWM program, you may just write an alternative script file or Jim offered one of his script files that will do the task.
- To monitor Power going through DUT for a safety switch for DUT, you can measure the Voltage of DUT from the blue and white wires that Jim has made for us and calculate the current by inserting a small resistor in the circuit and determine the current by Ohm’s law
- For a connection of the pump-plumbing system on TU, it may be permanently attached, but preferred to be detachable. You may also use the tapped holes on the heat sink and use O-ring to seal any leak.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
- For testing purpose, use RTD sensors. This may be acquired through Jim or simply buy them. They are relatively cheap
- monitor the thermal resistance between the DUT and TU. This can be calculated by the temperature difference between TU and DUT over Power (needs to be calculated) into DUT.
- Direct control of water flow by RTD can be an issue. The relation may not be linear.
Risks and Areas of Concern
At the moment, few issues were being faced while putting all separate functional LabView programs together
Resources or Information Required but not Available
Solid State Relay switch (SSR):
It was provided by our sponsor last week but was broken. It will be available to pick up on Tuesday.
