Product Description
Onset Differential Air Pressure Transducer Sensor - T-VER-PX3UL
The T-VER-PX3UL transducer can measure either air pressure or velocity with the flip of a switch. The PX3 is available in three installation configurations: duct, panel or universal. Duct and panel models have two pressure and velocity range options: 0-1" WC / 0-3,000 ft/min or 0-10" WC / 0-7,000 ft/min with seven field-selectable sub-ranges for pressure and eight for velocity. All variants are available with and without display. The PX3 has an IP65/NEMA 4 environmental rating.
Requires analog input option during RX3000 or U30 system configuration and use of a S-FS-CVIA when using the H22-001 data logger. When using a U12 data logger, this sensor requires an 0-5 Vdc analog input cable (CABLE-ADAP5) and external power provided by an AC adapter (AC-SENS-1).
Highlighted Features
Switch-selectable ranges and scales reduce setup time High reliability sensor technology for long-term maintenance-free operation Monitors positive and negative pressure for application versatility
This sensor operates in an indoor environment.
