WS600-UMB

• All in One
• Aspirated temperature/humidity measurement
• Maintenance-free operation
• Open communication protocol
From the WS product family of professional intelligent measurment transducers with digital interface for environmental applications.
Intergrated design with ventilated radiation protection for measuring:
- Air Temperature
- Relative humidity
- Precipitation intensity
- Precipitation type
- Precipitation quantity
- Air pressure
- Wind direction
- Wind speed
Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature.
Precipitation is measured by way of a 24 GHz Doppler radar, which measures the drop speed of an individual drop of rain/snow.
Percipitation quantity and intensity are calculated from the correlation between drop size and speed.
The difference in drop speed determines the type of percipitation (rain/snow).
Maintenance-free measurement offers a major advantage over the common tipping spoon and tipping bucket processes.
Ultrasonic sensor technology is used to take wind measurements (WS600 only).
Measurement data are available for further processing in the form of a standard protocol (Lufft-UMB protocol).
