AV Sensors
Wall-Mounted Pressure Transmitters
Pressure Transmitters for Building Automation
AV Sensors wall-mounted differential pressure transmitters provide local pressure indication and conditioned outputs for building automation, HVAC and controlled-room monitoring. Available configurations range from a straightforward two-wire 4–20 mA transmitter to display-equipped products with configurable pressure units, auto-zero calibration, relay contacts and remote communications.
Applications include cleanrooms, pharmaceutical laboratories, surgical rooms, room-pressure monitoring, duct static-pressure measurement, and fan or chiller monitoring. Three product platforms allow system designers to select the display, output, configuration and installation features appropriate for their application.
