Can a thermocouple get too hot
You can run into problems if you choose the wrong type of thermocouple when inputting the settings into the transmitter during installation. This is a common error, as there are numerous types of thermocouples – types K, J, N, E, T, R, S, and B – each with a different range, accuracy, and electrical output. Solution: … See more If you accidentally reverse the polarity of the thermocouple lead wires, the measured temperature will be incorrect by the difference in temperature of the two ends of the leads. The problem is understandable … See more No two batches of wires are exactly alike. As the alloy percentages vary a tiny bit during each manufacturing process, some error in thermocouple accuracy is unavoidable. … See more A thermocouple should be grounded at only one location. If it is grounded at more than one location, a “ground loop” can be created with current flowing through the thermocouple from one ground to the other. This is likely to … See more Because a thermocouple measures temperature differentials, any temperature fluctuations around the reference junction (cold junction), which has the known temperature, result in an erroneous temperature reading. … See more WebAnswer (1 of 2): The actual thermocouple is a spot weld of two dissimilar metals so you should be OK up to near the melting point of those materials. However, the insulation …
