The Model 177 Low Range transmitter measures pressure ranges from 0-3" W.C. to 0-8" W.C. and provides a 3.0 mV/Vdc signal. All wetted surfaces, including flanges and diaphragms, are constructed of 316 stainless steel with a sealing Viton® O-Ring for excellent corrosion resistance. A standard 500 PSI static line pressure and single side overpressure rating are featured with these transmitters. .
