Veris PX3ULN05 Dry Differential Pressure / Velocity Transducer
The Veris PX3ULN05 pressure transducer, dry, universal, LCD/Digital. Monitors duct and room pressure in commercial buildings (replaces PXULN05S)
Overview
The Veris PX3ULN05 is a universal enclosure differential pressure and air velocity transducer designed for dry air and inert gas applications. It provides a selectable measurement range up to 10 inches of water column (WC) or up to 7,000 feet per minute in velocity mode. With a built-in LCD display, IP65 protection, and Bluetooth configuration, this sensor is reliable and easy to set up in commercial and industrial HVAC systems.
