PTX 100
The PTX-100 is excellent and cost-effective 2-Wire Temperature TRANSMITTER. The design is available in HEAD mounting and DINRAIL housing. The device generates 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.
