The TV2 differential pressure Sensor (-2″WG to +2″WG ±0.004″WG) uses two clear plastic tubes to sense the pressure of two different areas; one measures positive pressure and the other measures negative pressure. The third connection to the pressure sensor is a 3.5mm jack-type wire which connects the sensor to the TV2 Clean Room Display.
The sensor enclosure can be mounted in the ceiling of the clean room, a wall, or anywhere desired. Distance from termination port plate will determine overall tube length. The positive and negative tubes ID 3mm; which connects via coupler to the wall termination port tube ID 9mm.
