ProDuct iDentification
quick install
The PW 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.
Mount sensor on a duct or pipe, across a pump, filter, or other pressure differential.1.
Wire as shown (see page 2).2.
Configure the jumpers (see page 2).3.

Blink Codes:
LED Color Status
Solid Green Normal operation.
Flashing Green Low > High; use port swap jumper or bidirectional mode.
Solid Red Differential pressure is too high; select a higher pressure range.
Flashing Red Gauge pressure over sensor range; reduce line pressure or replace with a
higher range device.
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 factory calibration.

Jumper Options Notes
JP1 Voltage (V) or Current (mA)
JP2 0-10V or 0-5V output span Use only if JP1 is set toV mode.
JP3 Slow or Fast Slow mode provides 5 second averaging for
surge damping.
JP6 Normal or Bidirectional Normal: 0 to F.S. pressure
Bidirectional: -F.S. pressure to +F.S. pressure;
output reads ½ when pressure is zero.
JP7 Normal or Port Swap 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.
JP8 Normal or Analog Reverse Normal: output increases as pressure increases;
Reverse: output is maximum when pressure
differential is zero and decreases as pressure
increases.
Caution: This product uses a half-wave rectifier power supply. If the installer is using
a transformer to power the device, do not use the same transformer to power other
devices utilizing non-isolated full-wave power supplies.
Optional: Connect Zero terminals to digital output (contact closure) of control
system.
Caution: Zero input is for dry-contact only. Do not apply voltage to the Zero
terminals.
