WS400-UMB Smart Weather Sensor:
From the WS product family of professional intelligent measurement transducers with digital interfaces for environmental applications. integrated design with ventilated radiation protection for measuring: air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, and air pressure. One external temperature sensor is connectable.
Air Temperature and Humidity:Â Temperature is measured by way of a highly accurate NTC resistor, while humidity is measured using a capacitive humidity sensor. In order to keep the effects of external influences (e.g., solar radiation) as low as possible, these sensors are located in a ventilated housing with radiation protection. In contrast to conventional, non-ventilated sensors, this allows significantly more accurate measurement during high radiation conditions. Air temperature values with reduced accuracy are available as service channels for additional information. Additional variables such as dewpoint, absolute humidity, and mixing ratio are calculated from air temperature and relative humidity, taking account of air pressure.
Air Pressure:Â Absolute air pressure is measured by way of a built-in sensor (MEMS). The relative air pressure referenced to sea level is calculated using the barometric formula with the aid of the local altitude, which is user-configurable on the equipment.
Precipitation: Tried and tested radar technology from the R2S-UMB sensor is used to measure precipitation. The precipitation sensor works with a 24 GHz Doppler radar, which measures the drop speed and calculates precipitation quantity and type by correlating drop size and speed.
Note: Devices with precipitation radar are subject to approval regulations that differ between countries.
