- Model WE100 - Barometric Pressure Sensor



This highly accurate Barometric Pressure Sensor covers a pressure range from 800 to 1100 mb. The barometric pressure transmitter is fully temperature compensated within an operating range of -40° to 65° C. The barometric pressure sensors are attached to 25’ of marine grade cable, with lengths up to 500’ available upon request. The barometric pressure transmitter's output is 4-20 mA with a two wire configuration.

One important parameter in monitoring weather systems is barometric pressure. Changes read by a barometric pressure meter or transmitter indicates weather front movement. Most weather stations include a barometric pressure sensor as one parameter they monitor. Barometric pressure transmitters are also used for many other applications including ocean buoys, ships, checking engine performance, airports, and many more. A major use for barometric pressure sensors is related to determining surface and ground water level readings.
