Built on the PS9800 platform, the BV9800 measures barometric and vacuum pressures. This unit can be used for weather application and for compensating for barometric pressure changes during aquifer testing, as well as for vacuum measurements in pipes or wells.
A 4-20 mA output device, the sensor measures up to 1102 mbar (16.0 PSIA).

Weatherproof ABS (IP66/67) enclosure
Quick-connect vacuum port
The BV9800 requires a datalogger or control system and 9 - 24 VDC excitation for operation; it achieves stability after a one-second warm-up time. The sensor comes equipped with an inlet quick-connect fitting that allows it to be easily attached to vacuum chambers, well seals or pipe systems. The internal electronic circuit controls the amount of current flowing through the loop based on the signal from the internal pressure sensor. The current flow increases linearly with pressure. At full-scale pressure (16 PSIA), the transmitter will draw 20 mA. A data acquisition/or control system then measures this current and computes the pressure.
