WRG口K sheathed thermocouple

WRGK sheathed thermocouple

Sheathed thermocouples are characterized by their slendershape,fast thermal response，vibration resistance，long service life，and ease of bending．These features make them widely used across various industrial and technological sectors, suchasaviation,atomic energy，petrochemical,metallurgy，machinery,and power, etc.Theyare particularly suitable for temperature measurement in environments where installation in narrow, curved pipelines is required,or where rapid response andminiaturization are crucial.

WRG□K series sheathed thermocouples are our products made with the fully imported equipment and technology，which feature the unique structure ina full-range of specification.This is the first such product introduced domestically.The product consists of sheathed thermocouple elements,mounting and fixing devices, wiring components,and other key parts.

WR□ series Assembled thermocouple

WR Assembled thermocouple

WR 口 assembled thermocouple is used for temperature measurement on the gases,liquid media,and fixedsurfacesat - 4 0 - 1 6 0 0 ^ { \circ } { C } .It iswidely used in non-explosion-proof areas in industrial areas,such as aviation,atomic energy，petroleum,chemical industry，metallurgy, machinery，etc.The assembled thermocouples usuallyconsist of temperature sensing elements,protective tubes,junction boxes,and mounting devices,etc.

Keyfeatures

Wide range of measurement, long service life,easy installation and operation. However, it is not vibration resistant, leading to Changes in its calibration characteristics after long-term operation.
