Chromel Alumel Thermocouple Strip ANSI for Thermocouple Plug Pin Material


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.

Thermocouple strips are used for thermocouple pin, thermocouple connecting elements .



TYPE K (CHROMEL vs ALUMEL ) is used in oxidizing, inert or dry reducing atmospheres. Exposure to vacuum limited to short time periods.

Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures.
