WS500
Compact all-in-one weather sensor for measurement of temperature, relative humidity, air pressure, wind direction and wind speed.
From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications. Integrated design with ventilated radiation protection for measuring: Air temperature, relative humidity, air pressure, wind direction and wind speed. One external temperature or rain sensor is connectable.
- Temperature, relative humidity, air pressure, wind direction and wind speed
- Ultrasonic/Wind, NTC/T, Capacitive/RH, MEMS capacitive/Pressure
- Compact all-in-one weather sensor, low power, heater, aspirated radiation shield, maintenance-free operation, open communication protocol
- RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, XDR and optional SDI-12
