WS601

Compact all-in-one weather sensor with measurement of temperature, relative humidity, precipitation, 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, precipitation, air pressure, wind direction and wind speed. One external temperature sensor is connectable.

  • Temperature, relative humidity, precipitation, air pressure, wind direction, wind speed
  • Ultrasonic/Wind, NTC/T, Capacitive/RH, MEMS capacitive/Pressure, Tipping spoon and bucket/Precipitation
  • 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 7 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 detection
