Product Description

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. Thermocouples in this series are available in a variety of materials, diameters and calibrations to meet your specific needs. Can be supplied with:
Pot-Protects the connection between the mineral insulated cable and the wire assuring a reliable and durable measurement.
Head- Protects the connections from dust, moisture and installations in areas classified as explosive atmosphere (explosion proof) and can be supplied assembled with temperature transmitter.
Our explosion proof head with thermosensors possess Compliance Certificate Ex. Certificate in accordance with the electrical equipment conformity evaluation regulation for explosive atmospheres (Certificate N° NCC 6788/10X Marking: BR-Ex d IIC T6 Gb IP66).
Wiring block- This assembly allows the directly use in the process or as replacement elements used in assemblies with protection tubes or with wells and heads;
Connectors - Allows an easy and quick connection with the wire or extension cables. The connector is polarized, the negative pin has a large diameter avoiding the inversion of the ink. Available in two sizes, standard and mini.
