An overview of the thermal resistor
WZ series industrial heat resistance as temperature measurement sensor, usually with temperature transmitter, controller and display instrument, process control system, to directly measure or control in the production of various - 200 ℃ to 500 ℃ within the scope of the liquid, steam and gas medium, as well as the temperature of the solid surface.
Thermal resistance is the use of the material when the temperature changes itself along with the change of resistance and characteristics to measure temperature. When the temperature of the measured medium body with the tonsure, measured the temperature of the temperature sensing element is the average temperature range of the medium.
Despite the appearance of various thermal resistance difference is very big, but they are roughly similar, the basic structure of the general temperature inductive element, insulation casing, protection tube, and junction box and other major parts
Assemble the characteristics of the thermal resistance
Compression spring type thermal components, ant-vibration performance is good.

The working principle of thermal resistance
Thermal resistance is the use of the material when the temperature changes, its resistance also along with the change of characteristics to measure temperature.When resistance changes, the work shows the temperature resistance of the meter.

The normal temperature insulation resistance
Thermal resistance at ambient temperature for 15-35 ° C, relative humidity is not more than 80%, test voltage for 10-100 - v (dc) electrode and outer casing of the insulation resistance between > 100 m Ω.
