Working principle of explosion-proof thermistor

It is based on the principle of gap explosion prevention to design junction boxes and other components with sufficient strength. All components that can generate sparks, arcs, and dangerous temperatures are sealed inside the junction box cavity. When an explosion occurs inside the cavity, it can be extinguished and cooled through the gap between the joint surfaces, so that the flame and temperature after the explosion cannot be transmitted outside the cavity, thus achieving explosion prevention.

The basic principle of thermocouple temperature measurement is that two conductors with different compositions form a closed circuit. When there is a temperature gradient at both ends, current will flow through the circuit, and there will be an electromotive force - thermoelectric force - between the two ends, which is called the Seebeck effect. Create a thermocouple calibration table based on the functional relationship between thermoelectric potential and temperature; The calibration table is obtained under the condition of a free end temperature of 0 ℃, and different thermocouples have different calibration tables.

When a third metal material is connected to a thermocouple circuit, as long as the temperature of the two contacts of the material is the same, the thermoelectric potential generated by the thermocouple will remain unchanged and will not be affected by the connection of the third metal to the circuit. Therefore, when using thermocouples for temperature measurement, a measuring instrument can be connected to measure the thermoelectric potential, and the temperature of the measured medium can be determined. When measuring temperature with a thermocouple, it is required that the temperature of its cold end (the measuring end is the hot end, and the end connected to the measuring circuit through a lead is called the cold end) remains constant, so that the magnitude of its thermoelectric potential is proportional to the measured temperature. If the temperature changes at the cold end during measurement, it will seriously affect the accuracy of the measurement. Taking certain measures to compensate for the impact caused by temperature changes at the cold end is called normal cold end compensation for thermocouples. Use dedicated compensating wires to connect with measuring instruments.
