From RS Pro a range of Type J, K, N and T wire type thermocouple temperature sensors that conform to IEC 60584. These thermocouples have a welded grounded junction for a fast response time and leads with a durable PTFE insulation

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

In a welded grounded junction the two thermocouple wires and sheath are welded together to form one junction at the probe tip. These thermocouples have a fast response time because all the thermocouple is making contact with the sheath allowing the heat to transfer easily.

• Welded grounded junction with fast response
• Conform to IEC 60584 standards
• PTFE insulated leads for for resistance to oils, acid, fluids and good mechanical strength and flexibility

These grounded junction Type J, K, N and T wire thermocouples are Ideal for test and development applications including test and measurement, temperature mapping and OEM applications
