This K-Type thermocouple is a replacement part for the Temperature High (K-Type) sensor. The thermocouple junction is housed at the end of a 200 x 3 mm AISI 310 stainless steel sheath. It has a one metre long cable that terminates in a mini plug (colour coded green to indicate thermocouple ‘type K’). The metal sheath of the type K thermocouple can withstand temperatures above 1000°C. However, the PVC insulation on the connecting cable has a working range of -10 to 105°C, so keep this cable away from the source of heat e.g. by clamping the sensor in position. Stainless steel 310 was selected as the material for the sheath for its properties as a poor conductor.
