Product Information
- The PX3 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
