P03/3 Modbus
Weather Stations
Modbus weather station for temperature, 3x brightness, wind speed, precipitation. Optional GPS receiver
Highlights
-
-
Weather sensor/combined sensor: sun sensor, electronic wind sensor, rain sensor, thermometer
- - Modbus RTU
The P03/3-Modbus and P03/3-Modbus-GPS Weather Stations measure temperature, wind speed and brightness (eastern, southern and western sun) and recognize precipitation.
The P03/3-Modbus-GPS additionally receives the UTC signals (Universal Time Coordinated) as well as the site coordinates via an integrated GPS receiver. The direction of the sun (azimuth) as well as its height (elevation) are calculated and indicated, too.
The devices are Modbus slaves with a RS485 interface and a RTU protocol. The Modbus master, such as PC, SPS or MC can read the P03/3-Modbus(-GPS) Weather Stations measurement values with "Function 04h (Read Input Register)".
Models:
N° 30146 P03/3-Modbus
N° 30147 P03/3-Modbus-GPS with GPS receiver
- Brightness measurement with three separate sensors for east, south and west. Recognition of twilight/dawn
- Wind measurement: The wind strength measurement takes place electronically and thus noiselessly and reliably, even during hail, snow and sub-zero temperatures. Even turbulent air and anabatic winds in the vicinity of the weather station are recorded
- Temperature measurement
- Heated precipitation sensor (1.2 watts): No false reports as a result of fog or dew. Dries quickly after precipitation has stopped
- P03/3-Modbus-GPS only: Integrated GPS receiver. Output of UTC (Universal Time Coordinated), position (degree of longitude and latitude) and position of the sun (azimuth, elevation)
