Thermocouple Not Reading Correctly at Harry Cairns blog

Thermocouple Not Reading Correctly. Turn the pilot light on for at least 30 seconds and the release it to see if goes out; If the cold junction compensating sensor becomes faulty the ‘zero point’ of the thermocouple circuit becomes uncertain, affecting the indicated temperature reading. Failure of the cjc process can be difficult to diagnose as it may not create an obvious ambient temperature offset. Use a multimeter to test the leads on the thermocouple when both on and off of the pilot setting mode to see if they maintain a charge. The simplest way to check that a thermocouple is working correctly is to simulate a measurement using a millivolt generator that plugs directly into the indicating device. System wiring, probes, and wire and junction. If the calibration does not match or copper. Thermocouple troubleshooting reference > advanced techniques > below are several things to try if your thermocouple is not reading. When troubleshooting thermocouple failure, the authors, james lafollette and john ochenas, recommend reviewing three key issues: If finding that the thermocouple does not read, the problem is most likely a bad connection, broken wiring, or open internally within the thermocouple. If it does, it’s a sign your thermocouple isn’t working correctly. Set the values given in the. Thermocouples require the connection wire conductors be of the same calibration type as the sensor.
