BACnet PTEC LCM - OAVS with High Speed Damper

The OAM (Figure 2) contains the air velocity sensor (a specialized differential pressure transducer), V/F conversion circuitry and solenoid for auto-zero function. Advanced digital signal processing produces a highly accurate reading of even the noisiest flow signals.
The auto-zero solenoid connects to the air velocity pressure transducer's inlet ports to enable automatic periodic re-calibration. This re-calibration ensures accurate, drift-free airflow measurement. Automatic re-calibration of the differential pressure transducers occurs upon system power-up and when airflows are stable with frequency selectable from 1 to 6 times a day.
