092 Rev. 12/2010

The 092 Barometric Pressure Sensor measures absolute atmospheric pressure and converts

it into a linear, proportional voltage, using digital computer technology.

The 092 features robust, low maintenance construction that will withstand a wide-range of

adverse weather conditions, and consistently collects reliable barometric pressure data.

Operation

The enclosure of the 092 sensor houses a solid-state

pressure transducer, with linearization and amplifica-

tion instruments, and a low power embedded CPU.

The standard range of the 092 is 600 to 1100 hPa,

which makes it suitable for elevations sea level to

10,000 ft. Other ranges can be configured with DIP

switches on the board of the barometer. The digital

range is always 600 to 1100 hPa.

Construction

enclosure with metal weather shield. It may be

mounted outside or inside a building

access to the sensing element
