Product Details
RS Pro Type J and K IEC Thermocouples with Adjustable Bayonet Probe
From RS Pro a range of Type J and Type K thermocouple temperature sensors conforming to IEC 584 standards with a grounded hot junction for a fast response time. These durable type J and Type K thermocouples have a 2 m long cable with flexible glass fibre insulation and a rugged stainless steel braid. The probe has a stainless steel sheath which is surrounded by an adjustable spring loaded bayonet connector which enables the thermocouple to fitted securely
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
