RS PRO Type K Thermocouple 2m Length, 6mm Diameter → +350°C / 6212271

RS Pro Type J and Type K IEC Thermocouple Probes with Washer Termination. From RS Pro Type K and Type J thermocouple temperature sensors conforming to IEC 584 standards. These durable thermocouples have a rugged design with a 2 m long glass fibre insulated wire surrounded by a 316 stainless steel braid. The probe is terminated with a stainless steel washer with a 6 mm internal diameter for measuring surface temperatures. These thermocouple temperature sensors have a grounded hot junction for a fast response time. 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. What is a Welded Grounded Junction?. 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. What is a Surface Thermocouple?. This thermocouple is designed for measuring the temperature on a surface. Most thermocouples have a sensing tip where there ends of the thermocouple wires are encased in sheaths or protection tubes which do not allow for measuring the temperature of a surface area. In surface temperature sensing thermocouples the exposed welded wire junction is housed in a magnet, adhesive patch, washer or bolt which provides a true surface contact. These thermocouple sensors are easy to install and use, the washer at the end of the sensor is simply positioned under a bolt or a rivet. Features and Benefits. Meets IEC 584 standards Durable glass fibre insulated cable with stainless steel braid Grounded hot junction for fast response time Easy to install washer termination. Applications. These Type J and Type K washer terminated thermocouple sensors are ideal for use in applications where low profile temperature detection is required and is commonly used for surface or pipe measurement applications
