Veris Industries PW2LX03S Transducer

The Veris Industries PW2LX03S is a high-performance wet differential pressure transducer engineered for precision monitoring across pumps, filters, and heat exchangers in commercial HVAC systems. This 2-wire, 4-20 mA transmitter features microprocessor-profiled sensors to ensure ±1% full-scale accuracy across its selectable ranges. Built with 17-4 PH stainless steel wetted parts and a rugged NEMA 4 die-cast aluminum enclosure, this unit is designed to withstand harsh mechanical room environments while providing reliable feedback for hydronic loops and chiller plant optimization.

Installation efficiency is maximized through field-selectable pressure ranges (0-5, 0-10, 0-25, and 0-50 PSID) and a local LCD display for immediate on-site verification. The dual-sensor design provides superior overpressure tolerance, reaching a burst pressure of 250 psi, which often eliminates the need for complex three-valve bypass manifolds. For high-stability readings in turbulent systems, the device includes jumper-controlled electronic surge dampening and a pushbutton auto-zero function to maintain long-term calibration without the use of trim pots.

Key Benefits for the Contractor

• Versatile Range Selection: A single PW2LX03S unit covers four distinct PSID ranges, reducing the inventory needed for various boiler and chiller differential pressure applications.
• Rugged Durability: The IP65 / NEMA 4 rated housing and stainless steel fittings protect internal circuitry from moisture and dust in industrial plant rooms.
• Reduced Callbacks: The automatic zero calibration and reverse polarity protection simplify commissioning and prevent common wiring errors.
• System Compatibility: Operates on standard 12-24 VDC loop power, making it a drop-in replacement for most 4 to 20 mA control loops.

Common Questions

Can the PW2LX03S be used for bidirectional pressure sensing?
Yes, the unit features a jumper-selectable bidirectional mode, allowing for pressure monitoring in both directions, which is particularly useful in systems where flow may reverse or for specific bypass applications.

What happens if I plumb the high and low ports incorrectly?
This model includes a port swap jumper. If the sensor is plumbed backwards, you can simply toggle the jumper to reverse the polarity of the pressure ports electronically, saving the labor of re-piping the 1/8" NPT connections.

Is a bypass valve assembly required for this transducer?
Due to the high overpressure rating (2x full scale) and 5x burst pressure, a bypass valve is typically not required for protection during system startup, though 17-4 stainless manifolds are still recommended for ease of maintenance and isolation.
