Thermocouple Sensors with wide operating temperature range

A thermocouple sensor consists of two dissimilar metals, joined together at one end. This junction is where the temperature is measured. A small voltage is produced by the two metals, which can be measured and interpreted by a control system. The dissimilar metals are individually insulated, and an overcoat is present to maintain an intimate bifilar configuration. TE Connectivity (TE) thermocouple sensors and assemblies are offered in a variety of standard styles to fit a wide range of applications. Class 1 thermocouples are built according to IEC584. Custom thermocouple solutions are available. TE offers decades of experience designing and manufacturing custom sensing solutions.

Frequently Asked Questions

Q: What is a thermocouple?

A:  A thermocouple is a device consisting of two different conductors (usually metal alloys) that produce a voltage proportional to a temperature difference between either ends of the pair of conductors.  In contrast to most other methods of temperature measurement, thermocouples are self-powered and require no external form of excitation

Q: What are the advantages and disadvantages of grounded thermocouples? 

A:  A grounded junction puts the junction in contact with the packaging, protecting, metal case. This allows for a faster response time, however, a grounded tip is susceptible to electromotive forces in the environment, which might cause potential errors in the measurement. An ungrounded junction, therefore, is one without a contact with the metal case. Thus, have slower response time, but is less likely to provide erroneous readings.
