Product Description

  MICC Thermocouple with metallic protection tube Which thermoelectromotive force is independent of the diameter, type or length of the wire used 

 

 

Thermocouple

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).
