Product Overview
The PW2 Series sensor is designed to accept high dierential pressure. Install the sensor on a duct or pipe across a
pump, lter, 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.

Operation
Jumper Notes
Port Swap/Norm Reverses polarity of the pressure ports (i.e. makes the LO port operate as the HI port and vice versa); used when the
sensor is incorrectly plumbed.
Bi-Dr/Normal Normal: 0 to F.S. pressure
Bidirectional: -F.S. pressure to +F.S. pressure; output reads 1/2 when pressure is zero.
Slow Avg/Fast Norm Slow mode provides 5-second averaging for surge damping.
Analog Rev/Norm Normal: Output increases as pressure increases;
Reverse: Output is maximum when pressure dierential is zero and decreases as pressure increases.
Bar/PSI Select output units.
Auto-Zero: Press and hold the Zero button for two seconds or provide contact closure on the auxiliary ‘Remote Zero’ terminal to
reset the output to zero pressure. To protect the device from accidental zeroing, this feature is only enabled when the detected
pressure is within 5% of factory calibration.
