Product Description
0.04mm-0.5mm B/R/S Type Platinum Rhodium Thermocouple Bare Wire

What is a Thermocouple?
A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created. The voltage can then be interpreted using thermocouple reference tables to calculate the temperature.

Type R, S, and B thermocouples are "Noble Metal" thermocouples, which are used in high temperature applications.
Type S thermocouples are characterized by a high degree of chemical inertness and stability at high temperatures. Often used as a standard for calibration of base metal thermocouples
Platinum rhodium thermocouple(S/B/R TYPE)
Platinum Rhodium Assembling Type Thermocouple is widely used in production places with high temperature. It is mainly used to measure temperature in glass and ceramic industry and industrial salting
Insulation material: PVC, PTFE, FB or as per the customer"s  requirement.
