New Digital Barometer from Vaisala

The Vaisala BAROCAP® Digital Barometer PTB330 is a new generation barometer designed for a wide range of high-end atmospheric pressure measurement.

The PTB330 series features extremely high accuracy. The PTB330 can incorporate one, two or three BAROCAP® sensors. When two or three sensors are used, the barometer continuously compares the readings of the pressure sensors against one another and provides information on whether these are within the set internal difference criteria.

This unique feature provides redundancy in pressure measurement. Thus, users also get a stable and reliable pressure reading at all times as well as a pre-indication of when to service or recalibrate the barometer.

In addition to instant pressure, it also provides the WMO pressure trend and tendency code.

The PTB330 can calculate and output the QNH and QFE pressures used especially in aviation. The QNH represents the pressure reduced to sea level, based on the altitude and temperature of the observation site. The QFE represents air pressure at the airfield elevation.

All data from the PTB330 can be transferred to a PC for examination by using MI70 Link Interface Software.

The Vaisala BAROCAP® Digital Barometer PTB330 features a multi-lingual, numerical, and graphical display allowing users to monitor measurement trends. The graph is updated automatically while measuring. It also provides a one-year measurement history.

The PTB330 can be used in aviation, professional meteorology, and in demanding industrial pressure measurement applications such as accurate laser interferometric measurement and exhaust gas analysis in engine test benches.
