Barometric Pressure Sensor

Barometric Pressure Weather Sensor

Environdata’s Barometric Pressure sensor is designed to measure atmospheric pressure in the range 800 to 1050 hecto-Pascals (hPa).

The sensor uses a MEMS (Micro Electro Machined System) element that has been laser trimmed for accuracy. This provides a highly accurate and stable sensor at a reasonable cost.

Features In Detail

Details & Advantages

The sensor housing is fully sealed to protect the electronics from the weather and includes a Gortex vent that allows the pressure changes to be detected without allowing moisture into the sensor electronics.

A two point factory calibration ensures high accuracy over the operating range.

The sensor is normally housed in the LH35 weather station cabinet. Housing must be vented to atmosphere but provide a ‘static pressure’ environment to remove pressure effects of wind over the sensor aperture.

The sensor cable is 3 core custom wound, which is shielded and UV stabilised with a weatherproof connector.
