BT-1/2 is a 2wire,smart temperature transmitter which can be programmed by dial switch.
It has measurement input for various RTD signal and converts this signal into 4-20 ma standard current signal after linear processing; a special signal can be set in advance
while the sensor is burnout or short. It is often installed into the junction box of temperature sensor’s head,
or matchedwith mounting bracket on standard DIN guide rail,Round and striped design for the mounting
hole can meet different requirements for the junction box.
