Product Description

Iron/ constantan thermocouple wire type j

Thermocouple wire allows temperatures to be measured electronically. A typical thermocouple construction consists of a pair of dissimilar metals that are electrically joined together at the sensing point and connected to a voltage measuring instrument at the other end. When one junction is hotter than the other, a thermal "electromotive" force (in millivolts) is produced that is roughly proportional to the difference in temperature between the hot and cold junctions.
Thermocouple wires with different varieties and specifications of our company can be applied in all kinds of thermocouples, the temperature ranges from -270ºC to 1800ºC. The thermocouple wires have excellent performance and are extensively used in the temperature measurement and control in different fields, such as metallurgy, chemical industry, petroleum industry, machinery-electric industry, energy industry, agriculture and military industry.
Types of thermocouple wire: K, J, T, E, N, B, R, S
