Barometric pressure meters and sensors for barometric pressure measurement



  • 4-20 mA output
  • Marine grade cable with strain relief

Barometric Pressure Sensors Product Description

Global Water’s 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 ft of marine grade cable, with lengths up to 500 ft available upon request. The barometric pressure transmitter’s output is 4-20 mA with a two wire configuration.

Global Water’s PC320 Barometric Pressure Meter and Controller uses the barometric pressure transmitter’s output to trigger alarms.  In addition, Global Water offers the GL500 Barometric Pressure Recorder, which adds recording capabilities to the barometric pressure transmitter.  The GL500 Barometric Pressure Recorder connects to the barometric pressure sensor’s 4-20mA output to record data.

Why Measure Barometric Pressure?
One important parameter in monitoring weather systems is barometric pressure.  Changes read by a barometric pressure meter or transmitter indicate 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.
