The PressureWatchPro wirelessly derives pressure differential between a Receiving unit and up to four separate Transmitting units, eliminating the need to run tubes. The system supports a wide range of differential pressure determination, from -2 inches of water to +2 inches of water, so there is no need to size the sensor to the application
Installer selects the buildings target pressure. The system is designed to maintain the specified pressure within 2 pascals (.008” wc). When using multiple transmitters, each transmitter pressure value is added proportionally to
calculate a resultant differential for the output control. The system periodically runs self-calibration throughout operation
The 0-10V output is derived from the differential pressure value and then processed through a PI function to control external equipment. The PI parameters are set up by the installer with support from the mobile application.
