WS401
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, precipitation and air pressure. One external temperature sensor is connectable.
- Temperature, relative humidity, precipitation and air pressure
- NTC/T, Capacitive/RH, Tipping bucket/Precipitation, 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
- FEATURES
-
- All-in-one housing concept of a compact weather sensor combining 4 measurement parameters in one housing with only one cable connection
- Built-in data pre-processing, universal interfaces and selectable output protocols
- Compatible with many commercially available Met/HydroMet dataloggers and PLS systems thanks to an open communication protocol
- Maintenance-free operation – no moving parts that can wear out
- Suitable for all climate zones; also for solar-powered automatic meteorological stations
- Ventilated temperature and humidity measurement according to WMO guidelines
