RS Pro Type K & Type J IEC Heavy Duty Glassfibre Insulated Thermocouple Probes

From RS Pro a range of type K and Type J thermocouple probes with a rugged construction that conform to IEC 584 standards. These thermocouple temperature probes have a 150 mm long, 4.5 mm diameter stainless steel probe sheath for protection against corrosion. The cable has a durable design with glassfibre insulation surrounded by a stainless steel overbraid. These thermocouples have a grounded hot junction which enables them to have a fast response time

How does a Thermocouple Work?

A thermocouple is a sensor used to measure temperature in a range of different processes. A thermocouple 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.

Features and Benefits

• Rugged stainless steel probe sheath for protection against corrosion
• Conforms to IEC 584 standards
• Welded, grounded junction for fast response times
• Rugged glassfibre insulated cable with stainless steel overbraid


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
