Barometric pressure sensors convert absolute atmospheric pressure into a linear, proportional voltage, which may be used in any meteorological program. The Met One 092 barometric pressure sensor brings in modern digital computer technology. An on-board CPU scales pressure measurements, provides temperature compensation and controls communications output.
This sensor is inherently stable and does not require periodic service or routine recalibration.
The enclosure houses a solid state pressure transducer, with linearization and amplification electronics along with a low power embedded CPU. The sensor 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.
