Thermocouples with a unified 4-20 mA output THAU-001, TXKU-001, TZHKU-001

Thermocouples (thermoelectric converters, temperature sensors) TKHAU-001, TKHKU-001, TZHKU-001 are designed to convert the temperature of the working end of the thermocouple into thermo-EMF. Thermoelectric converters are used to measure the temperature of liquid, bulk and gaseous media that do not contain substances that interact with the material of the protective fittings and the connecting cable.

The field of application of thermocouples - systems for monitoring and regulating the temperature of technological processes in various areas of industry, agriculture and utilities, everyday life.
The operating principle of the thermocouple is based on the thermoelectric effect Seebeck... The thermocouple has two soldered ends, one end is placed in the measuring environment and is called a working or hot junction, and the other end, at the point of connection to the device input, is a cold junction. When there is a temperature difference between the hot and cold junction in the circuit, a thermo-EMF occurs, the value of which is fed to the input. The working junction is placed in a protective armature.

Main technical characteristics of 4-20 mA thermocouples
