Barometric Pressure Sensors

barometric_pressure_sensors.jpg (6921 octets)Barometric Pressure Sensors convert absolute atmospheric pressure into a linear, proportional voltage, which may be used in any meteorological program.

Features

  • Compact size
  • Weatherproof enclosure
  • Remote output
  • Permanent calibration

These sensors are inherently stable devices that do not require periodic service or routine recalibration.

Operation

The enclosure houses a solid-state pressure transducer, with linearization and amplification electronics.

The Model 090D is housed in a heavy duty fiberglass enclosure, suitable for harsh and severe environments. A hose barb is provided to enable the connection of a 1/4" sampling tube to the outside environment.

The Model 091 is contained within a small polycarbonate enclosure, and may be mounted outside or inside a built-in or other enclosure. Small inlet holes allow the atmospheric pressure access to the sensing element.

The standard range of the 090/091 is 26-32 in. Hg, suitable for elevations sealevel to 1500 feet. Other ranges are available.
