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.

China’s “One Belt, One Road” initiative is promoting electricity demand in emerging markets in Asia, Africa, the Middle East and South America. As the core equipment of the production, transmission, use and electric energy characteristic transformation, motors play an important role in all industries and sectors of modern society. And how is the sensor that is a key component of the motor control system to promote the development of industrial motors? Please watch this webinar.
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.
