Multi-point explosion-proof thermal resistance features

Spring type temperature sensing element, good vibration resistance; High measurement accuracy; No need to compensate wire, save costs; Imported thin film resistance components, reliable and stable performance.

Working principle

Explosion-proof thermal resistance is to use the gap flameproof principle of multi-point explosion-proof thermal resistance selection, design with sufficient strength of junction box and other components, all will produce sparks, arc and dangerous temperature parts are sealed in the junction box cavity, when the cavity explosion, multi-point explosion-proof thermal resistance, through the joint surface clearance flameout and cooling. The flame and temperature after explosion can not be transmitted outside the cavity of the multi-point explosion-proof thermal resistance model, so as to carry out flameproof.
