APPLICATIONS
• Monitoring and controlling
pump differential pressure
• Chiller/boiler differential
pressure drop
• CW/HW system differential
pressure
The PW2 Series 2-wire, 4 to 20 mA wet pressure transducers incorporate
microprocessor profiled sensors for exceptional accuracy and reliability.
Easy to use and designed to provide exceptional installation savings,
the PW2 Series is ideal for measuring pressure across pumps, filters,
heat exchangers, compressors, and other non-corrosive wet media
applications.
The optional pre-assembled bypass valve is designed for easy
maintenance and a one-step installation.
Jumper selectable
The jumper-selectable output
switch for normal (4 to 20 mA) or
reverse (20 to 4 mA) operation
provides application flexibility
Dual sensor
Dual sensor design for improved
overpressure tolerance
…
eliminates the requirement for
a bypass valve assembly in most
applications
Rugged
Rugged, die-cast enclosure
provides NEMA 4 sealing
High stability
Jumper-controlled electronic
surge dampening for high
stability
Selectable
Selectable differential units: psid
or bard
Zero calibration
Pushbutton zero calibration – no
trim pots to adjust
…maintain
accuracy and reduce callbacks
with automatic zero calibration
