Measuring building pressure and air velocities or volumes doesn’t get any easier than with the BAPI EZ Pressure Sensor. The revolutionary mounting system allows for 2.75” snaptrack, DIN rail or surface mounting, and the three Outputs and 10 Pressure Ranges are field selectable by simply turning the rotary switch and pressing the “Next” button. The auto-zeroing process is also very easy — simply turn the rotary switch to zero, push the button, wait for five seconds, turn the rotary switch back to your pressure range and walk away.
Besides being easy to set up and install, it is also accurate, rugged and economical. The heart of the unit is a micro-machined silicon pressure sensor. The sensor design inherently provides excellent accuracy, repeatability and stability.
The unit features a rugged NEMA 1 rated enclosure with short circuit proof outputs and reverse polarity protected inputs to perform under real world conditions.
The LCD display helps with troubleshooting because it displays the actual differential pressure over the entire operational range (5 to +5 inches W.C. or -1,250 to 1,250 Pascals) regardless of which individual pressure range is selected for output to the system controller.

Zone Pressure Pickup Ports
Features & Options
- Economical & Easy to Install
- Includes 80 Micron Filter
- Accommodates 1/8” I.D. to 5/32” I.D. Tubing
The Wall Pressure Pickup Port comes standard on a brushed stainless steel plate or in a Delta Style enclosure, both sized to fit a common 2” x 4” electrical box. A foam gasket seals the plate or enclosure to the wall. The Wall Plate and Delta Style Enclosure can be used for pressure alone or as a combination temperature sensor and port.
BAPI also offers a Ceiling Mount Square Cover that fits a standard 3/4” thick suspended ceiling tile and a rectangular version with a 2” x 4” electrical box.
The Low Profile Port is ideal for locations where aesthetics are as important as the pressure measurement. The only visible portion is a flush 7/8” dot on the wall. The built in surge damper smoothes out rapid variations in air pressure for a more stable reading.

Outside Air Pressure Pickup Port
Features & Options
- Economical & Easy to Install
- Accommodates 1/8” I.D. to 5/32” I.D. Tubing
- Rooftop, Wall or Vertical Mount
BAPI’s Outside Air Pressure Pickup Port is an easy, economical and attractive way of measuring outdoor static pressure. The pickup port also helps stabilize readings because it significantly reduces the pressure fluctuations caused by wind gusts.
Differences in building pressure are caused by the operation of supply fans or exhaust fans and usually measure less than .1 inches of water column (W.C.). A gentle breeze of 10 MPH provides a pressure of .048 inches W.C., while a strong wind of 40 MPH provides .772 inches W.C. A gale of 75 MPH can measure over 2.7 inches. BAPI’s pickup port significantly reduces these wind pressures for a stable and accurate reading at the pressure sensor and controller.
The unit is also very rugged with a UV-resistant and flame-retardant housing to perform and last under harsh conditions. It is available in Rooftop or Wall Mount or Vertical Mount for building soffits or ceilings.

The BAPI Differential Pressure Switch is ideal for air filter monitoring, static pressure proving, airflow proving or auxiliary fan actuation. Because of its UL 353 Limit Control Listing, the BAPI Switch can be used in safety circuits to protect heating appliances, heating systems, processing systems and HVAC/R systems.
The setpoint is field adjustable from 0.1” to 35” W.C, and the unit can measure positive pressure, vacuum or true differential pressure. The seven pressure ranges are field selectable by changing a color-coded spring. The spring for the range that you order is preinstalled, and the other six springs are shipped with the unit so that you can change ranges in the field if you choose.
The unit features a rugged plastic enclosure that protects the electrical terminations and pressure adjustment screw which is easily accessed through a port in the front cover using a square screwdriver bit (BA/SQ1BIT). The quick connect wiring terminations are accessed by opening the hinged cover. The unit is very compact and can be mounted directly on a flat surface with the rugged mounting feet, and the pressure barbs accept 3/16” or 1/4” tubing.
The unit also features an extremely high proof pressure of 100” W.C. so that it will continue tofunction properly even if it is accidently connected to an unusually high or low pressure.
