Veris Industries PWXX04S Transducer

For high-performance hydronic monitoring, the Veris Industries PWXX04S is a vet-preferred wet differential pressure transducer designed to eliminate commissioning headaches. This 0-100 PSID capable unit utilizes a microprocessor-profiled sensor to maintain ±1% full-scale accuracy across multiple switch-selectable ranges. Whether you are balancing pump differential pressure or monitoring chiller/boiler pressure drops, the NEMA 4 rated die-cast aluminum enclosure ensures the electronics remain protected from moisture and industrial debris. The field-selectable 4-20mA out, 0-5V, or 0-10V signal provides universal compatibility with high-end BAS and PLC controllers. A standout feature for the field tech is the jumper-selectable port swap, allowing you to fix "backwards" plumbing errors via software logic rather than costly pipe refitting. With electronic surge dampening (5-second averaging) and a 17-4 PH stainless steel wetted parts construction, the PWXX04S is built to handle the transients of high-pressure water systems without signal noise or mechanical fatigue.

• Field-Selectable Flexibility: Includes four switchable ranges (10/20/50/100 PSI) and three output signals to reduce truck stock.
• Labor-Saving Port Swap: Jumper-selectable logic corrects high/low port plumbing errors instantly without re-piping.
• Automatic Zero Calibration: Pushbutton and remote zero-adjust terminals prevent sensor drift and minimize maintenance callbacks.
• Industrial Durability: Robust NEMA 4 enclosure and stainless steel media compatibility for non-corrosive liquids.
• Advanced Surge Damping: Jumper-controlled electronic dampening stabilizes readings in turbulent hydronic systems.

Can I use this for gauge pressure?
Yes. To measure gauge pressure, simply leave the low port open to the atmosphere or piped to the reference point. Ensure you select the 100 PSI range to accommodate the maximum system pressure.

How do I fix a "Low > High" error?
If the dual-color LED is flashing green, the high and low ports are reversed. Instead of re-piping, simply move the internal port-swap jumper to the 'Swap' position to normalize the 4-20mA signal.

Does this require a three-valve bypass?
While often recommended for easier maintenance, the PW series' high proof pressure (2x FS) and burst rating (5x FS) provide a significant safety margin that may simplify bypass requirements in many standard hydronic applications.
