   BAPI's High Pressure Zone Pressure Transmitter is an accurate, rugged and economical solution for measuring and reporting duct/building static pressure, room-to-room differential pressure or air velocities/volumes. It is available in two rugged, IP66-rated enclosures or a 2.75” snaptrack mount, and features 5 pressure ranges from 0-5 to 0-30 W.C. (0-1,250 to 0-7,400 Pascals).

   The heart of the unit is a micro-machined silicon piezoresistive pressure sensor specifically developed for low pressure. The sensor receives a five-point error correction over the compensated temperature range for excellent accuracy, repeatability and stability.
  
   The Pressure Ranges and Outputs are all field selectable with DIP switches, and the auto-zeroing process is very simple (flip a switch, wait five seconds, flip it back and walk away). The unit also features short circuit proof outputs and reverse polarity protected inputs to perform under real world conditions.
  
   The optional Static Pressure Probe Assembly connects to the high port of the unit and includes a built in surge damper which smoothes out the signals for a more stable reading.

Pressure Probe Assemblies The Static Pressure Probe and Total Pressure Probe Assemblies connect to the BAPI Zone Pressure Sensor to provide duct static pressure or duct air velocity. The angled total probe faces into the airflow to sense the moving air’s total pressure while the static probe senses static pressure.

Pressure Pickup Ports BAPI makes a full line of Room, Wall and Ceiling Pressure Pickup Ports, including the new Outside Air Pressure Pickup Port, to accompany the Zone Pressure Sensors. The Room and Wall units can be used for pressure alone or as a combination temperature sensor and pickup port.
