Piezoresistive Level Transmitter- Series PLT
2-wire, Loop-Powered, ±0.25% Accuracy
Series PLT Piezoresistive Level Transmitters provide reliable measurement and control of process levels by sensing the hydrostatic pressure in a tank. The loop-powered level transmitter delivers a 4-20 mA output signal proportional to hydrostatic pressure and specific gravity of the fluid for indicating, recording or control purposes. Easily accessible zero and span potentiometers make calibration in the field quick and simple. Units are equipped with EMI and reverse polarity protections.
