621-2158 RS PRO Type K Thermocouple 1m Length, 2mm Diameter → +250°C

RS Pro IEC PTFE Grounded Welded Tip Wire Thermocoupless_x000D_ 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_x000D_ How does a Thermocouple Work?_x000D_ 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_x000D_ Welded Grounded Junction_x000D_ 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._x000D_ Key Features and Benefits_x000D_ • Welded grounded junction with fast response_x000D_ • Conform to IEC 60584 standards_x000D_ • PTFE insulated leads for for resistance to oils, acid, fluids and good mechanical strength and flexibility_x000D_ Applications_x000D_ 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_x000D_ Standards_x000D_ IEC-BS 4937 60584-2 & IEC-BS 4937 60584-3
