Mineral Insulated Thermocouple Sensor with M8 x 1mm Threaded Pot Seal

Product Code: TPM8

Available with probe diameters ranging from 0.5mm up to 8.0mm and supplied with an epoxy resin sealed M8 x 1.0mm threaded pot seal (8.0mm Ø x 19mm long).

The pot is epoxy resin sealed to prevent moisture ingress (resin rated for continuous use up to +135°C). A high temperature resin is also available for continuous use up to +220°C.

Various probe sheath materials are available and the sensors can be used in a wide variety of applications, with temperatures ranging from as low as -100°C and up to +1300°C.

The mineral insulated construction enables the sensors to be bent, twisted or flattened without impairing performance. The bending radius of the sheath is 10 x probe diameter; this can be reduced to 4 x, if required.

This product can be supplied with a calibration certificate. Contact sales for further information. This product can be supplied with a calibration certificate. Contact sales for further information.
