RK900-10 Ultrasonic Automatic Weather Sensor

RK900-10 Ultrasonic Automatic Weather Sensor

RK900-10 automatic weather instrument secara bersamaan mengukur atmospheric temperature, atmospheric humidity, air pressure, wind speed, wind direction, solar radiation, illuminance, dust concentration, dan precipitation.

Sensor temperature, humidity, dan air pressure ditempatkan di dalam radiation shield, sedangkan wind speed dan direction menggunakan prinsip ultrasonic. Rainfall terdeteksi dengan 24G radar detection, yang dapat dengan cepat mengukur rainfall dan intensitasnya.

Internal GPS global positioning module dan electronic compass memberikan indikasi latitude dan longitude serta relative speed, yang dapat menghitung real dan virtual wind speed serta direction, sehingga sangat cocok untuk dipasang pada motion vector seperti special vehicles atau vessels. Berbagai functional modules dan measurement parameters dapat dikombinasikan sesuai kebutuhan pengguna.
