Veris Industries PWLX03S Transducer

The Veris Industries PWLX03S is a professional-grade wet media differential pressure transducer engineered for high-accuracy monitoring in HVAC and process control systems. Built with microprocessor profiled sensors, this unit delivers precise 0 to 50 PSID measurements across chillers, boilers, and heat exchangers. The integrated LCD display provides real-time local indication of differential pressure, while the rugged NEMA 4 enclosure ensures reliable operation in demanding mechanical rooms. For contractors, the standout feature is the jumper-selectable port swap, which corrects improper plumbing electronically—eliminating the need for costly physical re-piping. With switch-selectable pressure ranges and a user-configurable output (4-20 mA, 0-5 V, 0-10 V), the PWLX03S provides maximum versatility for pump differential pressure monitoring and cooling water system balancing. The 17-4 PH stainless steel wetted parts provide excellent media compatibility, ensuring long-term stability and reducing callbacks on the job site.

• Electronic Port Swapping: Correct cross-piped high/low lines via a simple jumper move, saving hours of labor on-site.
• Selectable Output & Range: Field-configurable 0-10V or 4-20mA signals and multiple PSID scales reduce the need to stock multiple SKUs.
• NEMA 4 Rated Protection: Die-cast aluminum housing protects sensitive wet differential pressure sensor electronics from moisture and dust.
• Advanced Surge Damping: Jumper-controlled 5-second averaging prevents "hunting" and stabilizes readings in turbulent hydronic systems.
• Maintenance Free: Push-button and remote zero adjustment allow for simple recalibration without adjusting internal trim pots.

Can I use the PWLX03S for both liquid and gas applications?

Yes, the 17-4 PH stainless steel construction is compatible with a wide variety of non-corrosive liquids and gases common in chiller/boiler differential pressure drop monitoring.

What happens if I over-pressurize the sensor?

The unit features a dual-color status LED. A flashing red light indicates that gauge pressure has exceeded the sensor range, allowing for immediate troubleshooting before hardware failure occurs.

Does this unit require a bypass valve assembly?

The dual-sensor design and high burst pressure rating (up to 5x full scale) mean the PWLX03S can often be installed without a traditional three-valve manifold, though one may be used for easier maintenance access.
