PT100 thermal resistance

Productoverview:

WZP series PT100 thermal resistance As the temperature measurement sensor, usually with temperature transmitter, controller and display instrument and other facilities, consisting of the process control system for direct measurement or control of the production process in a variety of -200 -500 DEG C range of liquid, steam and gas solids and surface temperature. Thermal resistance is the use of the material when the temperature changes with its own resistance characteristics change to measure the temperature. When the measured temperature gradient exists in the medium, the measured temperature is the average temperature of the temperature sensing element to the range of medium. Although the shape differences between the various thermal resistance is large, but their basic structure but broadly similar, generally have a temperature sensing element, insulating sleeve, protective tube, the main part and the junction box etc..

Two, work principle:

WZP series of PT100 thermal resistance is the use of the material when the temperature changes, the resistance also changes with the characteristics to measure the temperature. When the resistance changes, the instrument will display relevant resistance temperature.

Three, technical parameters:

Insulation resistance at room temperature

100MΩ。">Heat resistance at ambient temperature is 15 to 35 DEG C, relative humidity is less than 80%, the test voltage is 10 - 100V (DC) >100M. The insulation resistance between electrode and outer tube.

Four, measurement of temperature and tolerance:

Note: t is the sense of temperature measured temperature component values (c)
