1, the pressure spring type temperature sensing element, anti vibration performance is good;

2, the measurement accuracy is high;

3, without the need to compensate the lead, save costs;

4, import film resistance element, the performance is reliable and stable;

The working principle of explosion proof thermal resistance is the use of the material gap explosion principle, design of a sufficient strength of the box and other components, all will produce sparks, electric arc and dangerous temperature components are sealed in the junction box cavity, when the cavity occurs when the explosion and cooling, so that after the explosion of flame and temperature can not be separated, so as to carry out.
