Features

• RS Pro IEC Type J ; Type K Grounded Junction Braided Thermocouple. From RS Pro Type J and Type K thermocouple temperature sensors conforming to to IEC 584 standards with a Class 1 tolerance for optimum performance. These thermocouple temperature probes have a rugged design with a 5 mm diameter, 2.5 m twin conductor cable insulated by glass silk and steel braid. The probe is enclosed in a stainless steel sheath for protection against corrosion. These thermocouples feature a grounded hot junction for a fast response time. How does a Thermocouple Work?. 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. Features and Benefits. Conforms to IEC 584 standards Grounded hot junction for a fast response time Class 1 tolerance for optimum accuracy Rugged design with steel braided cable Stainless steel sheath for corrosion resistance. Applications. Type K Thermocouples (Nickel-Chromium / Nickel-Aluminium) are the most common type of thermocouple and are both accurate and flexible with a wide temperature range. Typical applications for these mineral insulated Type-K thermocouple probes include heat exchangers, power stations, brick and cement kilns, heat treatment and annealing furnaces, thermostats, food thermometers, vehicle diagnostics and in laboratories Type J Thermocouples (Iron-Constantan) have a smaller temperature range and a shorter lifespan at higher temperatures than the Type K but has the same reliability. Type J thermocouples are ideal for monitoring the temperatures of inert materials and in vacuum applications. Applications include heat processes such as the manufacturing of plastic and resin and in electrical furnaces
