RS Pro IEC Mineral Insulated Fast Response Type K Thermocouple with Threaded Pot and Tails

From RS Pro a range of type K thermocouple temperature sensors or probes that conform to IEC 584 standards. These thermocouple temperature probes have a 0.5 mm diameter for a fast response and a single element insulated hot junction for a reduction in electrical interference. The thermocouple has a robust construction with a 310 stainless steel probe sheath which is mineral insulated for flexibility enabling it to be bent and formed to suit a wide range of applications. The leads of the thermocouple have a durable PFA insulation. This thermocouple also features an M8 x 1.00 mm fine pitch threaded pot seal with a temperature rating of 200°C.

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 an Insulated Junction?

An insulated or ungrounded junction is where the thermocouple wires are welded together and fully covered by but insulated from the outer protective sheath, often by the use of mineral insulation. The advantage of this is that there is a reduction in electrical interference and a stable reading

What is Mineral Insulation?

Mineral insulation is used to insulate the thermocouple wires from one another and from the metal probe sheath that surrounds them. The sheath is filled with a highly compacted magnesium oxide powder that prevents the conductors from making contact with one another other than at the fixed junction. The high density of the mineral powder enables the thermocouple to have a rapid response as it promotes a fast heat transfer between the conductor and the sheath. Mineral insulation also helps to protect the thermocouple wire from environmental damage including corrosion, prevents electrical interference and allows the cable to be flexible whilst maintaining its mechanical strength

Features and Benefits

• Insulated hot junction for reduced electrical interference
• Mineral insulation for flexibility, durability and high performance
• Conforms to IEC 584 standards
• Flexible, can be bent into shape for easy installation
• 0.5 mm probe diameter for a fast response
• 310 stainless steel sheath for resistance to corrosion and oxidation
• M8 x 1.0 mm fine pitch threaded pot seal
• Sensor temperature range of -100 to +800°C
• PFA lead insulation for resistance to oils, acid, fluids and good mechanical strength and flexibility

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
