WS3000 Reference Weather Sensor


New class of Smart Weather Sensors with high-quality aluminum housing: WS3000 Climate Reference Sensor for Calibration / Verification of Air Temperature, Relative Humidity, Air Pressure

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.

Accuracy in Detail:

  • Temperature better than
  • ±0.1 °C
  • Relative Humidity better than ±2 %
  • Air Pressure better than ±0.1 hPa

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

  • Parameters measured: Temperature, relative humidity, air pressure (redundant pressure as option)
  • high-quality full-metal construction with ventilated radiation shield for air temperature / humidity measurements
  • Traceable accuracy
  • Modular architecture
  • Drift-free sensing technologies
  • Easy maintenance and calibration possibilities
  • Interfaces: RS485, 2-wire, half-duplex/WiFi
