BAROMETRIC PRESSURE TRANSMITTER
pressure meters and sensors for barometric pressure measurement
- 4-20 mA output
- Marine grade cable with strain relief
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’ 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.
Global Water's PC300 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
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. For more information on this please go to
