Senex explosion-proof thermal resistor temperature meter

Explosion-proof thermal resistance uses the gap explosion-proof principle to design junction boxes and other components with sufficient strength. All parts that can produce sparks,arcs and dangerous temperatures are sealed in the junction box. When an explosion occurs in the box,it can be The surface gap is extinguished and cooled so that the flame and temperature after the explosion cannot be transmitted outside the cavity box,thereby preventing explosion.

The compression spring type temperature sensing element has good vibration resistance; no compensation wires are needed,saving costs; the measurement accuracy is high; the imported thin film resistor element has reliable and stable performance.

Usually used in conjunction with display instruments,recording instruments,electronic computers,etc. Directly measure the temperature of liquid,steam and gas as well as solid surface in the range of -200°C to 500°C where hydrocarbons and other explosives exist at various production sites.

?Normal temperature insulation resistance
When the ambient temperature of explosion-proof thermal resistance is 15~35℃,the relative humidity is not more than 80%,and the test voltage is 10~100V (DC),the insulation resistance between the electrode and the outer sleeve is ≥100MΩ.m
