Description
Product introduction:
Model: WREK
Name: armoured thermocouple
Manufacturer: Shanghai Automation Instrumentation Co., Ltd.
Application: WREK armoured type thermocouple 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, it is usually used with display, recorder and electronic regulator. Moreover, it can also be the temp sensor element of assembly-type thermocouple. It can measure temp of liquid, stream, gas and surface of solid range 0℃～700℃ in all production processes.
