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.
