The PTX-100 is excellent and cost-effective 2-Wire
Temperature TRANSMITTER. The design is available in
HEAD mounting and DINRAIL housing. The device
g`enerates 4-20mA current signal proportional to
temperature. The TRANSMITTER operates on loop power
supply. The current signal reduces wiring cost
drastically. The effect of electrical noise is
minimized & long runs of thermocouple wires is
eliminated. The housing is shockproof & hermetically
sealed.
