Features

• RS Pro Type J IEC Thermocouple Probe with Leaf Termination. From RS Pro a Type J thermocouple temperature sensor conforming to IEC 584 standards designed for connecting to a surface. This thermocouple has a robust design with a glass fibre insulated cable surrounded by a stainless steel braid. The cable is terminated with a stainless steel shim which allows the thermocouple to be welded or soldered into place on a flat surface. These thermocouples have a grounded hot junction for a fast response time. What is a Thermocouple?. A thermocouple is a sensor ***d to measure temperature in a range of different processes and consists of two wire legs made from different metals joined together at their two ***s 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 beca*** 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 ***s 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 ho***d in a magnet or adhesive patch or, in this case terminated on to a stainless steel shim or 'leaf'. which provides a true surface contact.
