Thermocouple consists of two wires, each made of different metal, welded together at one end. When the

 welded point(measuring junction) is heated, a thermoelectromotive force is produced that is proportional

 of the temperature difference between the welded point and the other end (reference junction).

 Therefore, by messuring this thermoelectromotive force either with the reference junction temperature kept

 constant or by using an automatic compensation curciut, the measuring junction temperature can be measured.

 The thermoelectromotive force of a thermocouple is independent of the diameter or length of the wire used and

 depends only on the type of wire used.

 

 The thermocouples in this series can be combined with various types of materials for protection

 tubes, which prolong the life of the sensor, it makes easier the replacement of the element without

 the need of process stops.

 The thermocouple can be supplied with smooth tube, fixed bushing with thread or with adjustable

 flanges and can be assembled with analog temperature transmitter, microprocessor with or without

 communication and protocols (for more information, please feel free to contact us).
