Barometric Pressure Sensors
Model 092

with Weather Shield Attached
 
Barometric Pressure Sensors convert absolute atmospheric pressure into a linear, proportional voltage, which may be used in any meteorological program. The Model 092 brings in modern digital computer technology. An on board CPU scales pressure measurments, provides temperature compensation and controls communications outp ut.

Features
• Compact size
• Weatherproof enclosure
• Digital and Analog outputs
• Permanent calibration
• Robust construction
• Customer configured output.
These sensors are inherently stable devices that do not require periodic service or routine recalibration.

Operation
The enclosure houses a solidstate pressure transducer, with linearization and amplification electronics along with a low power imbedded CPU.
The Model 092 is contained within a small polycarbonate enclosure, and may be mounted outside or inside a building or other enclosure.
Small inlet holes allow the atmospheric pressure access to the sensing element.
The standard range of the 092 is 600 to 1100 hPa suitable for elevations sea level to 10,000 ft.
Other ranges can be configured with DIP switches on the board of the barometer. Digital range is always 600 to 1100 hPa.
