How do dirty connections impact thermocouples?

Dirty connections can significantly impact thermocouples by causing continuity problems due to low output. Thermocouples rely on the accurate conduction of electrical signals that result from temperature differences at the junction of two dissimilar metals. When connections become dirty or corroded, the electrical contact can weaken, leading to poor signal transmission.

This degradation results in reduced thermoelectric output, meaning that the voltage generated by the thermocouple in response to changes in temperature may not be sufficient for accurate readings. Low output can hinder the functionality of temperature control systems, potentially leading to incorrect temperature measurements and unsafe operating conditions. Ensuring that connections are clean and free of contaminants is essential for the reliable performance of thermocouples in any gas-operated equipment.
