Heat treating thermocouples are thermal processing sensors that allow equipment operators to accurately measure and maintain the right temperatures for softening, hardening, and material modification. A faulty thermocouple can result in inaccurate measurements, so it’s critical for quality management personnel to determine when and why thermocouple failure has occurred. GeoCorp, Inc., has provided a series of short articles that walk operators through assessment and troubleshooting of thermocouples that go bad.
Sometimes the smallest issues can lead to big problems. When your business relies on crucial temperature readings from your thermocouples, it can pay to pay identify individual factors that may have cause part failure. ~ James LaFollette, GeoCorp, Inc.
When troubleshooting thermocouple failure, the authors, James LaFollette and John Ochenas, recommend reviewing three key issues: system wiring, probes, and wire and junction. In addition, the following could cause misreadings:
- metal fatigue
- oxidation
- contamination
- poor installation
