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 protocolls: UMB-Binary, UMB-ASCII, SDI-12, MODBUS, NMEA.

  • Parameters measured: Temperature, relative humidity, air pressure (redundant pressure as option)
  • Measurement technology: PT100/Temp, Capacitive/RH, MEMS Resonant Pressure transducer
  • Product highlights: Compact all-in-one weather sensor, heater, aspirated radiation shield, maintenance-free operation, open communication protocol
  • Interfaces: RS485, 2-wire, half-duplex/WiFi

Advantages of the WS3000 Climate Reference Sensor
  • New class of Weather Sensor with high-quality aluminum housing
  • Traceable accuracy, due to detailed calibration certificates, performed by an accredited laboratory for every sensor
  • Modular architecture, which allows easy maintenance and calibration possibilities for every single sensor
  • Drift-free sensing technologies
  • Excellent survivability under extreme conditions
  • Full-metal construction with ventilated air temperature / humidity measurements

Accuracy in Detail:

  • Temperature better than +/- 0.1°C
  • Relative Humidity better than +/- 2%
  • Air Pressure better than +/- 0.1 hPa
