Heavy Duty Thermocouples

MITSCO manufacture a wide range of Heavy Duty thermocouple assemblies with different element combinations K, N, R and S in Simplex and Duplex. This range of thermocouple has been developed to withstand the most demanding of environments, where the effects of thermal, physical and chemical attack are prevalent making the correct selection of materials used to build a thermocouple critical, if optimum cost effective performance is to be achieved.

Listed below are some of the Heavy Duty thermocouple assemblies available from MITSCO.

Thermocouples can be built to order with alternative Sheath and Conductor and Junction types, please contact our Sales Office for details 01527 882553.

General purpose heat resistant material suitable for use up to 900ºC.

Heat resistant steel suitable in sulphur bearing atmospheres suitable up to 1150ºC.

Excellent high temperature strength not suitable in sulphur atmospheres good corrosion resistance maximum operating temperatures 1200ºC.

Suitable for use up to 1250ºC high physical strength suitable in oxidising and carburising and reducing atmospheres.

Often used as an inner sheath, in conjunction with a Steel outer sheath to provide a combination offering physical strength from the outer steel sheath and a barrier to corrosion of the thermocouple element. (Use with type R and S element combinations.

This can be used as nonporous ceramic inner sheath, used where total protection to the inner thermocouple is required. Higher operating temperature (1750ºC) than the Aluminous Sheath and greater resistance to thermal and physical shock.

Hot Junction Type

Insulated

Most commonly constructed Junction Type, offers protection to Thermocouple element, but slows response time.
