WPR2 SERIES
Installation & Operation Instructions
GENERAL INFORMATION
The ACI WPR2 Series Remote Wet to Wet
Differential Pressure Transmitter is designed to
reduce installation time and provide mounting
flexibility, often eliminating the need for
additional plumbing and manifolds. The WPR2
can be ordered with standard CMP rated PVC
cable or with a metal clad cable. The metal clad
cable provides end to end protection of the
cables with flexible metal conduit, durable and
resistant 304 stainless steel construction. The
WPR2 accurately measure wet media pressures
in a variety of applications. Commonly used
for monitoring pumps, these devices are also
ideal for measuring pressure across filters, heat
exchangers and compressors. The dual remote
sensors are based on a ceramic capacitive
sensing element with ¼"-18 NPT male (304
stainless steel) fittings. The WPR2's enclosure
opens conveniently to allow it to be reconfigured
between three additional ranges and outputs of
4 to 20 mA , 0 to 5 VDC, or 0 to 10 VDC (default).
The different configurations in this series can
measure both uni or bi-directional pressure
ranges as low as 3 psi and as high as 300 psi,
depending on the unit.
Precautions:
•
Do not switch pressure range and output
mode when power is on. Make sure
to power off the unit first, then move
jumpers to the correct positions and
then power on the transmitter.
•
Do not apply any external voltage to
zero terminals.
•
Do not replace pressure sensors with any
other sensors. Do not interchange the
high and low sensors. The high and low
sensors are specifically calibrated to the
WPR2 unit.
Any changes to the sensors will void the
product warranty
MOUNTING INSTRUCTIONS
The WPR2 is supplied with 4 mounting flanges.
The mounting flanges must be installed onto
the bottom of the enclosure. Align the mounting
flanges with the threaded insert on the bottom
of the enclosure. Insert and tighten down the
screws.
