Movable thread Armored Thermocouple WRNK-321 WRNK-331 Brief Description

Movable thread Armored Thermocouple WRNK-321 WRNK-331 is armored type with fixed thread connection,Armored Thermocouple WRNK-321 WRNK-331 has advantages of being able to bend, high temp resistance, quick thermal response time and being sturdy and durable etc. Like industrial assembly-type thermocouple, as sensor of temp measurement, Movable thread Armored Thermocouple WRNK-321 WRNK-331 is usually used with display, recorder and electronic regulator. Moreover,Movable thread Armored Thermocouple WRNK-321 WRNK-331 can also be the temp sensor element of assembly-type thermocouple. Movable thread Armored Thermocouple WRNK-321 WRNK-331 can measure temp of liquid, stream, gas and surface of solid range 0℃~1000℃ in all production processes. It is as per GB/T18404-2001 standard.
