Multi point explosion-proof thermistor

Characteristics of multi-point explosion-proof thermistor

Pressure spring type temperature sensing element with good anti vibration performance; High measurement accuracy; No need to compensate for wires, saving costs; Imported thin film resistor components with reliable and stable performance.

Working principle

Explosion proof thermistor is a multi-point explosion-proof thermistor selected based on the principle of gap explosion-proof. It is designed with a junction box and other components with sufficient strength to seal all parts that can generate sparks, arcs, and dangerous temperatures inside the junction box cavity. When an explosion occurs inside the cavity, the multi-point explosion-proof thermistor can extinguish and cool through the gap between the joint surfaces, preventing the flame and temperature after the explosion from transferring to the multi-point explosion-proof thermistor model outside the cavity, thus achieving explosion-proof.
