The PW2 Series sensor is designed to accept high differential pressure. Install the
sensor on a duct or pipe across a 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.

Port Swap/Norm Reverses polarity of the pressure ports (i.e. makes the LO port
Bi-Dr/Normal Normal: 0 to F.S. pressure
Slow Avg/Fast Norm Slow mode provides 5 second averaging for surge damping.
Analog Rev/Norm Normal: output increases as pressure increases;

oPeration
Auto-Zero: Press and hold the Zero button for 2 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 fac tory calibration.

incorrectly plumbed.
Bidirectional: -F.S. pressure to +F.S. pressure; output reads ½ when
pressure is zero.
Reverse: output is maximum when pressure differential is zero and
decreases as pressure increases.
Range: Use the Range switch to select
F.S. differential pressure.
