You can run into problems if you choose the wrong type of thermocouple when inputting the settings into the transmitter during installation. Selecting the Wrong Type of Thermocouple on the Transmitter The following are the six most common causes of thermocouple measuring errors, followed by ways to rectify them: 1. The measured voltage is converted into a temperature unit, with the temperature reading displayed on a device or transmitted to a remote location.Īlthough thermocouples are reliable, temperature measurement errors can occur for various reasons.

A thermocouple works by taking the difference in voltage between the two junctions, explained by the Seebeck effect. At the other end, the wires are connected to a body of a known temperature, called the reference junction. Two wires, each made from a different metal, are joined at the tip. Thermocouples measure temperature differentials, not absolute temperatures. Relatively inexpensive compared to other temperature measurement technologies, thermocouples are valued for their ability to measure a wide temperature range: from –200° to +1250☌ (–328° to +2282☏).

Thermocouples are robust temperature measurement devices that are accurate enough for many industrial and scientific applications. This article discusses the six most common causes of thermocouple errors. Thermocouples are among the most popular temperature measurement instruments in industrial applications because of their versatility and ease of use.
