Wet Media Differential Pressure Transducer
Product Overview
The PW2 Series sensor is designed to accept high differential pressure. Install the sensor on a duct or pipe across a
PW2xxxS
pump, filter, heat exchanger, compressor, or other non-corrosive wet media. The dual sensor design eliminates the
need for a bypass valve, and the bi-directional capability reduces installation errors. A pushbutton allows easy zero
adjustment.
