Why Thermocouples Fail. the thermocouple is one of the most popular temperature sensors. Despite its high reliability, it can indicate erroneous measurement values for. thermocouple failure often begins with a reduction in seebeck voltage, which occurs over the course of several weeks and is not easy to notice. The seebeck voltage is the direct conversion of temperature differences to electrical voltage. although a sensor can be damaged by an extreme mechanical shock event, most failures are caused by ongoing vibration, loose terminations, corroding connections, or chemical attack. These can weaken the sensor and wiring, causing the number of spikes and dropouts to increase over time. a faulty thermocouple can result in inaccurate measurements, so it’s critical for quality management personnel to determine when and why. In this article, we will explore the common reasons for thermocouple failure and how to prevent them. however, like any mechanical device, thermocouples can fail. so, why do thermocouples go bad? thermocouples are high temperature devices and regular exposure to high temperatures, repeated temperature cycling and even physical abuse will have a detrimental effect on the metallurgy of the thermocouple elements causing irreversible changes. Various factors such as mechanical damage, overheating, and contamination.
