The Barometer is intended for measuring atmospheric pressure within the range from 300 to 1100 hPa or mbar (225 to 825 mmHg), it provides chart plotters and instrumental displays with barometric pressure data.
This product is designed for weather monitoring. The sensor is located inside the device case. Many chartplotters and digital navigation instruments are able to display data on pressure in the form of graphs (modern Vulcan7, old ST70) or show a trend indicator; this allows tracking of trends in the weather change.
Pressure data output resolution to a NMEA 2000 Version 3 network is 0.01 hPa (mbar), absolute measurement accuracy is ±1 hPa, relative measurement accuracy is ±0.12 hPa. We also recommend our Humidity Sensor YDHS-01, it will provide your instruments with relative humidity, air temperature and calculated dew point temperature.
Device is plug and play, works right our of the box and does not require any settings. Calibration of the Barometer has been performed by the manufacturer. Therefore, you can set an offset from -10.0 to +10.0 hPa for the sensor readings to align with readings from other ship equipment. Programming of the NMEA 2000 device instance, system instance, data instance, description strings is also supported.
The Barometer can be configured by user to turn on or off specified channels of digital switching equipment. The conditions can be either the actual atmospheric pressure or the difference between actual pressure and the pressure 30 minutes or 1 hour ago.
