Product Description
Alumel chromel Dia 8 mm rod thermocouple alloy type K
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 other industry.
Types of thermocouple wire: K, J, T, E, N, B, R, S
