Met One 092

Barometric pressure sensor

Part # 51123

092 barometric pressure sensor

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.

  • Compact size

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
