Bare Wire Thermocouple Wire 0.1mm To 12mm Types K /J /E/ T
Tankii Thermocouple wire is available in Standard Limits, Special Limits or Extension Grade accuracy as defined in ANSI/ASTM E230 (or Class 1 , 2 or 3 in IEC 60584).
The simplest thermocouple is made using a bare wire configuration, that is two thermoelements joined at one end and directly exposed to the atmosphere of the operating environment.
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.
