Technical work of integrated explosion-proof thermistor

The change in thermoelectric potential (resistance) measured by the integrated explosion-proof thermistor during operation generates an unbalanced signal through the bridge of the temperature transmitter, which is amplified and converted into a 4-20mA electrical signal for the working instrument to display the corresponding temperature value Explosion proof thermocouple (resistor) utilizes the principle of gap explosion-proof. When an explosion occurs inside the chamber, it can extinguish and cool through the gap between the joint surfaces, preventing the flame and temperature after the explosion from being transmitted outside the chamber, thus enabling temperature measurement. The thermoelectric potential (resistance value) generated by the thermocouple (resistor) passes through the bridge of the temperature transmitter to generate an unbalanced signal, which is amplified and converted into a 4-20mA DC electrical signal to the working instrument. The working instrument displays the corresponding temperature value.

The output of the integrated explosion-proof thermistor is a consistent 4-20mA signal; Can be used in conjunction with microcomputer systems or other conventional appearances. Users can also request to make it an explosion-proof or fire-resistant measuring device with a temperature transmitter on the outer surface. A thermal resistor, also known as an integrated explosion-proof thermal resistor, refers to an amplification and transmission module (i.e. temperature transmitter) installed in the waterproof or explosion-proof junction box of a thermal resistor, which is integrated with the sensor and outputs a standard 4-20mA current signal or can also output 0-5V or 1-5V voltage signals. Generally used in conjunction with displaying appearance, recording appearance, electronic computers, etc., to directly measure the temperature of liquid, vapor, gas media and solid surfaces within the range of 0-500 degrees during various production processes
