Type K Thermocouple WRCK-191 WRCK-192 Brief Description

Type K Thermocouple WRCK-191 WRCK-192 with no fixed device,With compensating lead wire,WRCK series armoured type Type K Thermocouple WRCK-191 WRCK-192 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, Type K Thermocouple WRCK-191 WRCK-192  is usually used with display, recorder and electronic regulator. Moreover, Type K Thermocouple WRCK-191 WRCK-192 can also be the temp sensor element of assembly-type thermocouple. Type K Thermocouple WRCK-191 WRCK-192 can measure temp of liquid, stream, gas and surface of solid range 0℃~400℃ in all production processes. It is as per GB/T18404-2001 standard.

 

Type K Thermocouple WRCK-191 WRCK-192  Working principle

Type K Thermocouple WRCK-191 WRCK-192 Thermocouple working principle: two conductors with different components are welded at both ends to form a loop, measuring temperature directly side is called measurement side, terminal side is called reference side. When the temperature between measurement side and reference side has a difference,Type K Thermocouple WRCK-191 WRCK-192 will generate heat in the loop current, then connected to the display instrument, And the instrument indicates the corresponding temperature value of the thermal electromotive force generated by the thermocouple. Thermocouple thermoelectric EMF will grow with the measurement temperature’s growth, The size of the thermal electromotive force is related to the temperature of both ends. It has nothing to do with the length, diameter of the thermode. Armoured Type K Thermocouple WRCK-191 WRCK-192 structure is made of conductor, insulation magnesia and 1Cr18Ni9Ti stainless steel protection tube after many times drawing. Junction box, protective tube, insulated casing, terminals and armoured thermocouple form a basic structure of assembly-type thermocouple, with a variety of installation of fixtures.

Type K Thermocouple WRCK-191 WRCK-192 Thermal response time

When the temperature appear step change, the thermocouple output variation is to the equivalent of 50% of the change, The time required is called the thermal response time “T0.5”

 

Thermal response time of armoured Type K Thermocouple WRCK-191 WRCK-192  should not be more than requirements of the following table:
