| Modèle 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. |
