Thermocouple temperature transducer

Thermocouple temperature transducer are the most common contact temperature measurement devices used in industry. This is because the thermocouple has the characteristics of stable performance, large temperature measurement range, long-distance signal transmission, simple structure and convenient use. Thermocouples can directly convert thermal energy into electrical signals and output a DC voltage signal, making it easy to display, record and transmit.

Commonly used thermocouple temperature transducers can be divided into two categories: standard thermocouple transducer and non-standard thermocouple transducer. The standard thermocouple transducer referred to refers to the thermocouple whose relationship between thermoelectric potential and temperature, allowable error, and a unified standard graduation table is specified in the national standard. Non-standardized thermocouple transducer are not as good as standardized thermocouples in terms of use range or order of magnitude, and generally do not have a unified indexing table, which is mainly used for measurement in some special occasions.
