1, Application of industrial platinum thermal resistance sensor

It is usually used in conjunction with display instruments, recording instruments, and electronic calculations. Directly measure the surface temperature of liquid, steam and gas medium and solid surface in the range of -200°C~500°C in the production process.

2, Features of industrial platinum thermal resistance

     • Compression spring type temperature sensing element, good anti-vibration performance;
     • No need to compensate the wire, saving cost;
     •High temperature measurement accuracy;
     • High mechanical strength, good pressure resistance;
     •Imported thin-film resistor elements with stable performance.

3. The working principle of industrial platinum thermal resistance

     Thermal resistance uses the characteristics of a substance that changes in temperature and its resistance changes with it to measure temperature. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value.

4. The main technical parameters of industrial platinum thermal resistance

     Product performance standards
     IEC751
     JB/T18622-1997
     JB/T8623-1997

 5. Insulation  resistance at room temper ature

The temperature of the platinum thermal resistance is 15-35°C, the relative humidity is not more than 80%, and the test voltage is 10-100V (DC). The insulation resistance between the electrode and the outer tube>100MΩ.
