Barometric Pressure

Affordable and accurate barometric pressure sensor

Beeservices barometric pressure sensors are accurate, stable, and durable, at an affordable cost.

High Accuracy and Stability

Accurate within 1.5 % across a pressure range of 15 to 115 kPa (4.43 to 34.96 in Hg). Long-term non-stability has been measured continuously indoors and in natural conditions (with sensors mounted inside a datalogger enclosure) for multiple sensors and is less than 0.5 % per year. Temperature effects on signal are less than 1 % across a wide temperature range (-20 to 50 C).

Typical Applications

Barometric pressure sensor applications include pressure measurement in weather networks, often for weather forecasting. They can also be used to correct the output of sensors that are sensitive to pressure changes (for example, Apogee oxygen sensors).

Low Power, Large Signal

Pressure sensor power requirement is approximately 35 mW (7 mA current draw at 5 V DC). Voltage output ranges from 0 to 5 V DC for a pressure range of 15 to 115 kPa

Wide Operating Range

Operating environment for sensors is -40 to 80 C and 0 to 100 % RH (non-condensing).

Small Size

Sensor is small and lightweight (16 mm diameter, 5 gram mass), facilitating easy deployment within a datalogger enclosure that keeps the sensor shields from solar radiation and precipitation.

Warranty and Support

All Beeservices products are backed by an industry-leading four year warranty and outstanding customer support
