USH-9 Precise Snow Depth measurement Ultrasonic Sensor

Features and advantages

  -  Continuous and non-contact measurement
  -  Reliable sensor for extreme environmental conditions and high alpine employment
  -  Robust, sealed and therefore maintenance free ceramic membrane with protective shield against ice and snow
  -  High level of accuracy thanks to the integrated temperature compensation and filtering of snow and rainfall using intelligent spectrum analysis
  -  Energy-saving operation through sleep modus, ideal for solar-powered measuring stations

 
Fields of application

The USH-9 is especially suitable for extreme weather conditions and so for alpine and high alpine terrain. Its high operational safety enables a permanent and reliable recording of measurement values, for which reason it is commonly used by meteorologists, avalanche warning services, ski regions, research stations and the energy sector.

 
Implementation

The snow depth is an important parameter for evaluating the snow pack. It must be regularly measured as the development of the snow pack is subject to strong regional and temporal fluctuations and significantly influenced by the current weather Ultrasonic Measurement of Snow Depth conditions (snow or rainfall, air temperature, wind etc.). The USH-9 is a non-contact device and therefore does not compromise the snow pack. It can measure depths of up to ten meters continuously and with convenient remote data transmission if needed.
