WS3100-UMB Reference Weather Sensor

New class of Smart Weather Sensors with high-quality aluminum housing: WS3100 Climate Reference Sensor for Calibration / Verification of Air Temperature, Relative Humidity, Air Pressure and Solar Radiation

Relative humidity is measured by means of a heated capacitive sensor element; a precision PT100 measuring element is used to measure air temperature. A resonant pressure transducer is employed for precise pressure measurement. Due to the integrated Kipp & Zonen CMP10 pyranometer, global radiation values are in a secondary standard quality. 

Accuracy in detail:

  • Temperature better than +/- 0.1°C
  • Relative Humidity better than +/- 2%
  • Air Pressure better than +/- 0.1 hPa
  • Solar Radiation better than 5% W/m2 (secondary standard)

Measurement output can be accessed by the following protocolls: UMB-Binary, UMB-ASCII, UMB-ASCII 2.0, SDI-12 and NMEA.

  • Temperature, relative humidity, air pressure (redundant pressure as option), global radiation
  • PT100/Temp, Capacitive/RH, MEMS Resonant Pressure transducer, Kipp&Zonen CMP10 / radiation
  • Metal housing with ventilated radiation shield temperature/humidity measurements, Traceable accuracy, Modular architecture, Drift-free sensing technologies, Easy maintenance & calibration possibilities, CMP10 Secondary Standard Kipp & Zonen Pyranometer, WiFi module
  • RS485, 2-wire, half-duplex/WiFi
  • 8391.U01
