RS PRO IEC Mineral Insulated Type K Thermocouple with 1.5 x 1000mm Probe


A durable and accurate type K thermocouple with a single element insulated hot junction reducing electrical interference and a 1.5 x 1000mm probe designed to be bent or formed to suit a wide range of applications. The type K thermocouple features flexible mineral insulation providing excellent response times with an M8 x 1.00 mm fine pitch threaded pot seal and 100mm PFA insulated twin twisted tails.

The type K thermocouple probe is constructed from Stainless Steel for its excellent strength and corrosion resistance and features IEC colour coded tails for quick identification helping prevent cross connection for a hardwearing thermocouple suitable for temperatures of -40°C to 1100°C.

The Stainless Steel thermocouple is suited to a wide variety of applications and is commonly used in heat exchangers, power stations, brick and cement kilns, heat treatment and annealing furnaces, thermostats, food thermometers, vehicle diagnostics and in laboratories.

Supplied in packs of 5, for packs of 1 see RS PRO 219-4371

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
