RS PRO Type J Thermocouple 6mm Diameter → +350°C

RS PRO Type Type J Thermocouple 6mm Diameter → +350°C

From RS PRO a Type K thermocouple temperature sensor designed for measuring heat changes in reducing atmospheres. This heavy duty thermocouple sensor has a rugged design with a glass fibre insulated lead and stainless steel over braid and its sensed temperature range of -60°C to +350°C means it is suitable for use in harsh environments.

How does a Thermocouple Work?

A thermocouple is a sensor used to measure temperature in a range of different processes and consists of two wire legs made from different metals joined together at their two ends to form two junctions. The hot, or measuring junction is connected to the body whose temperature is going to be measured. The cold junction or reference junction is connected to a body of known temperature. When the measuring junction is placed on something hot a voltage or potential difference between this and the reference junction occurs. This voltage can then be converted into a temperature measurement using thermocouple reference tables. This process is also known as the Seebeck Effect

Properties of Glassfibre Insulation

Glassfibre wire insulation is flexible with a good temperature range but does not prevent the ingress of fluids
