Introducing the USH-9 – The Precise Snow Depth Sensor

Precision is key when it comes to measuring snow depth, and that’s where the USH-9 comes in. This ultrasonic sensor is designed for precise, continuous and non-contact recording of snow depths, making it an ideal choice for extreme weather conditions and high alpine terrain.

Features and Benefits:

  • Continuous and Non-Contact Measurement: The USH-9 measures snow depth without coming into contact with the snow pack, providing accurate results.
  • Robust Design: The sealed ceramic membrane and protective shield against ice and snow make the USH-9 a reliable choice for extreme environmental conditions.
  • High Accuracy: The USH-9 features integrated temperature compensation and filtering of snow and rainfall using intelligent spectrum analysis, ensuring a high level of accuracy.
  • Energy-Efficient Operation: The USH-9 has a sleep mode, making it ideal for solar-powered measuring stations.

Fields of Application

The USH-9 is widely used by meteorologists, avalanche warning services, ski regions, research stations, and the energy sector due to its high operational safety and reliable measurement values.

Implementation

Measuring snow depth is important for evaluating the snow pack, as its development is subject to strong regional and temporal fluctuations influenced by weather conditions such as snow or rainfall, air temperature, and wind. The USH-9 measures depths of up to ten meters continuously and can transmit data remotely if needed, making it a convenient choice for remote locations.

In conclusion, the USH-9 is the solution for precise and non-invasive snow depth measurement. With its robust design, energy-efficient operation, and high accuracy, it is the ideal choice for extreme weather conditions and high alpine terrain.
