Thermocouple compensation cable characteristics introduction and classification

Thermocouple compensation cable which is a pair of insulated conductor wires having a temperature equal to the nominal value of the thermoelectromotive force of the matched thermocouple in a certain temperature range (including normal temperature), and is used to connect the thermocouple to the measuring device. To compensate for errors in the temperature changes at the junction of them with the thermocouple. Divided into extended type and compensated type. Thermocouple compensation wire types are classified into SC, KC, KX, EX, JX, TX, and NC according to the product type.
Thermocouple compensation cable features and uses
 · This product is made of PVC insulation and sheath, which has excellent moisture, abrasion and flame retardant properties.
 · The thermocouple compensation cable consists of a certain number of twisted compensation wire pairs (or the shield compensation wire is twisted and cabled, and then covered with shielding layer, sheath, armor layer.
 ·The compensation line pairs are all in the form of twisted pair. The shielding layer is divided into copper wire braided shield, aluminum-plastic composite tape wrapped shield, and copper-plastic composite tape according to materials.
   Winding shielding, according to the structure, the total shielding, the shielding and the total shielding.
 • compensating cable is used to connect the thermocouples and measuring devices in the area to compensate for errors in the temperature changes at their junction with the thermocouple.

 ·Intrinsically safe anti-riot temperature measurement system The thermocouple compensation cable adopts low-inductance and low-capacitance structure. Besides the performance of the above-mentioned thermocouple compensation cable, it also has explosion-proof and safety performance.
