APPLICATIONS
● Monitoring and controlling pump differential pressure
● Chiller/boiler differential pressure drop
● CW/HW system differential pressure
FEATURES
● The jumper-selectable output switch for normal (4-20mA) or reverse
(20-4mA) operation provides application flexibility
● Rugged, die-cast enclosure provides NEMA 4 sealing
● Jumper-selectable port swap feature eliminates costly replumbing when the
high and low ports are improperly plumbed...change the jumper position from
normal to swap – problem solved!
● Switch-selectable pressure ranges...fewer models to order and stock
●
Pushbutton and remote zero adjustment...maintain accuracy and prevent
callbacks with automatic zero calibration
● Jumper-controlled electronic surge dampening for high stability
●
Pushbutton zero calibration – no trim pots to adjust

DESCRIPTION
The PW Series wet/wet pressure transducers incorporate microprocessor profiled
sensors for exceptional accuracy and reliability. Easy to use and designed to provide
exceptional installation savings, the PW Series is ideal for measuring pressure across
pumps, filters, heat exchangers, compressors, and other non-corrosive wet media
applications.
Microprocessor provides digital signal conditioning
● Noise rejection reduces fluctuating readings due to noise or turbulence
●
Surge damping prevents false alarms by averaging fast peaks
