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 SPECIFICATIONS Product Operating Environment -10 to 55 °C (14 to 130 °F); 0 to 90% RH non-condensing WARRANTY Limited Warranty5 years AGENCY APPROVALS MICROPROCESSOR PROVIDES DIGITAL SIGNAL CONDITIONING • Noise rejection reduces fluctuating readings due to noise or turbulence • Surge damping prevents false alarms by averaging fast peaks 0 Actual PressureDigitally Conditioned Output TIME F.S.
