Summary
WZ series of industrial thermal resistance as temperature measurement sensor, usually with temperature transmitter, regulator and display instrument and other auxiliary use, the composition process control system, with a direct measurement or control of various production processes in the -200 -500 temperature range of liquid, steam and gas medium and solid surface temperature.
Thermal resistance is based on the material in the temperature change resistance itself also as characteristic changes occur to measure the temperature of. When measured in the medium in the presence of a temperature gradient and the measured temperature is average temperature in the temperature sensing element where the medium range.
Although the various thermal resistance of different shapes, but their basic structure is generally similar to the general feeling of temperature components, insulation casing, protective tube, and junction boxes and other major components
Characteristic
- pressure spring type temperature sensing element, anti vibration performance is good;
- high temperature measurement accuracy;
- high mechanical strength, good performance;
- import film resistance element, stable and reliable performance.
Working principle
Thermal resistance is used to change the temperature of the material, its resistance is also with the characteristics of the occurrence of changes in temperature measurement. When the resistance changes, the instrument will display the corresponding resistance temperature value.
