Type K Thermocouple WREK2-301 WREK2-302

Type K Thermocouple WREK2-301 WREK2-302 Brief Description

Type K Thermocouple WREK2-301 WREK2-302 is armoured type with double output signal, Flexible adjustable thread joint without junction box, WREK series armoured type Type K Thermocouple WREK2-301 WREK2-302 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 WREK2-301 WREK2-302 is usually used with display, recorder and electronic regulator. Moreover, Type K Thermocouple WREK2-301 WREK2-302 can also be the temp sensor element of assembly-type thermocouple.Type K Thermocouple WREK2-301 WRNE2-302 can measure temp of liquid, stream, gas and surface of solid range 0℃～700℃ in all production processes. It is as per GB/T18404-2001 standard.

Type K Thermocouple WREK2-301 WREK2-302 Working principle

Type K Thermocouple WREK2-301 WREK2-302 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, it 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 WREK2-301 WREK2-302 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 Type K Thermocouple WREK2-301 WREK2-302  form a basic structure of assembly-type thermocouple, with a variety of installation of fixtures. Armoured thermocouple has two kinds: insulation type and shell connecting type.

Type K Thermocouple WREK2-301 WREK2-302 Main technical parameter

Type K Thermocouple WREK-301 WREK-302 Temperature measurement range and tolerance

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

Type K Thermocouple WREK2-301 WREK2-302 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 Type K Thermocouple WREK2-301 WREK2-302 should not be more than requirements of the following table:
