Affordable and accurate barometric pressure sensor

Apogee Instruments' 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)
  Low Power , Large Signal
Pressure sensor power requirement is approximately 35 mW (7 mA current drain at 5 V DC). Voltage output ranges from 0 to 5 V DC for a pressure range of 15 to 115 kPa.
Barometric Pressure Sensor from Apogee Instruments
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.
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).
  Warranty and Support
All Apogee products are backed by an industry-leading four year warranty and outstanding customer support.
