Mixer features
4-20 ma two wire output, strong anti-interference ability;
Save the compensation conductor and temperature transmitter installation cost;
Safe and reliable, long life;
The cold end temperature automatic compensation, nonlinear correction circuit;
Working principle of the pieces
Thermocouple (resistance) in the working status of the change of the thermoelectric potential (resistance), after the temperature transducer of bridge produce unbalance signal, after amplification into 4-20 ma electrical signal to the instrument, the instrument will display the corresponding temperature value.
Flame-proof thermocouple (resistance) using the clearance flame-proof principle, when an explosion cavity, can remove from heat and cooling by joint clearance, the explosion flame temperature and not reach outside the cavity, thereby for temperature measurement.Thermocouple (resistance) produce thermoelectric potential (resistance) after temperature transmitter of bridge produce unbalance signal, after amplification into 4-20 ma dc signal to workers instrument, the instrument shows the corresponding temperature value.
