The integration of explosion-proof working principle of thermal resistance is? Flame-proof thermal resistance in the task form (measured by the thermoelectric potential Resistance) Change of temperature transmitter of bridge, the unbalanced signal after shrink into 4 - 20 ma electrical signal transmission instrument to a task, the task instrument and display the corresponding temperature value.
the flame-proof heat resistance the clearance flame-proof principles, when there is explosion cavity, can after stall joint clearance and cooling, the explosion flame temperature and not reach outside the cavity, and a temperature measurement. Thermocouple ( Resistance) The thermoelectric potential ( Resistance) Temperature transmitter of bridge, the unbalanced signal is converted into 4 - after shrinking 20 ma dc signal to workers instrument, the task instrument shows the corresponding temperature value.
