WPR2 SERIES
Installation & Operation Instructions
GENRAL INFORMATION
The ACI WPR2 Series Remote Wet to Wet
Di erential Pressure Transmitter is designed to
reduce installation time and provide mounting
exibility, often eliminating the need for additional
plumbing. They accurately measure wet media
pressures in a variety of applications. Commonly
used for monitoring pumps, these devices are also
ideal for measuring pressure across lters, heat
exchangers and compressors. The dual remote
sensors are based on a ceramic capacitive sensing
element with ¼"-18 NPT male (304 stainless steel)
ttings. The WPR2's enclosure opens conveniently
to allow it to be recon gured between three
additional ranges and outputs of 4 to 20 mA , 0 to 5
VDC, or 0 to 10 VDC (default). The di erent
con gurations 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
o the unit rst, 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
speci cally calibrated to the WPR2 unit.
Any changes to the sensors will void the
product warranty
MOUNTING INSTRUCTIONS
The WPR2 is supplied with 4 mounting anges.
The mounting anges must be installed onto the
bottom of the enclosure. Align the mounting
anges with the threaded insert on the bottom of
the enclosure. Insert and tighten down the screws.
Find a suitable location for the enclosure. Drill
