Splash proof WRCK-421 WRCK-422 Armored Thermocouple Brief Description

Splash proof WRCK-421 WRCK-422 Armored Thermocouple with fixed flange connection, splash proof type,WRCK series armoured type Type K Thermocouple WRCK-421 WRCK-422 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, Splash proof WRCK-421 WRCK-422 Armored Thermocouple is usually used with display, recorder and electronic regulator. Moreover, Splash proof WRCK-421 WRCK-422 Armored Thermocouple can also be the temp sensor element of assembly-type thermocouple.Splash proof WRCK-421 WRCK-422 Armored Thermocouple can measure temp of liquid, stream, gas and surface of solid range -40℃～400℃ in all production processes. It is as per GB/T18404-2001 standard.

 

Splash proof WRCK-421 WRCK-422 Armored Thermocouple Main technical parameter

Temperature measurement range and tolerance

Category	Code	Graduation	Outer diameter of well mm	Temperature℃	Max temp℃	Allowed error △t
						Measuring range℃	Allowed error value
Cu-CuNi	WRCK	T	≥Φ3	350	400	＜-200	Not provided
						-40～350	±0.75%t

Note：1）It is the absolute value of measuring temperature.
