Key features

 

  • All-in-one housing concept of a compact weather sensor combining several measurement parameters in one housing with only one cable connection
  • First and only compact weather sensor with integrated Kipp & Zonen CMP10 Pyranometer with secondary standard quality
  • Built-in data pre-processing, universal interfaces and selectable output protocols
  • Maintenance-free operation – no moving parts that can wear out
  • Compatible with many commercially available Met/HydroMet data loggers and PLS systems thanks to an open communication protocol
  • Suitable for all climate zones; also for solar-powered automatic meteorological stations
  • Ventilated temperature and humidity measurement according to WMO guidelines
  • Integrated heater that can be switched on if there is danger of frost

 

The WS310-UMB Smart Weather Sensor for measuring of air temperature, relative humidity, solar radiation and air pressure. Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. The world renowned technology of Kipp & Zonen CMP10 is integrated. Measurement output can be accessed by the following protocols: UMB-Binary, UMB-ASCII, SDI-12, MODBUS. One external temperature or rain sensor is connectable.
