The three transducers arranged at equal intervals on the horizontal plane are designed exclusively by Vaisala. The measurements of atmospheric pressure, temperature, and humidity are integrated into a PTU module that performs capacitive measurements for each parameter. The PTU module can be easily replaced. The WXT520 eliminates concerns about overflow, clogging, wetness, and losses due to evaporation during rainfall measurements. The precipitation measurement of the WXT520 is based on the unique Vaisala RAINCAP sensor, which detects the impact of individual raindrops. The signals generated from the impacts are proportional to the volume of the raindrops. Therefore, it is possible to directly convert the signals from each raindrop into rainfall amounts. The WXT520 measures rainfall, rainfall intensity, and rainfall duration in real-time. For more details, please contact us.
