Snow Pack Analyser SPA-2:
Automatic and continuous measurement
To measure certain snow parameters can be a challenging task. Therefore, several different variables have to be measured to be able to provide reliable information about the whole snow pack. In addition, snow has a considerable variability in space and time. Until now, only punctual measurements for certain values were possible. With its strap sensors and different system assembly versions the Snow-PackAnalyser System (SPA) now constitutes a revolutionary innovation for an automatic, continuous, and most importantly areal measurement of the parameters snow depth, snow water equivalent (SWE), snow density, and the contents of liquid water and ice. For this reason the significance and reliability of the data about the snow pack‘s state can be increased substantially.
The SPA enables a modern, up-to-date data recording with a high resolution over time. Moreover, the system helps to reduce the often dangerous and expensive employment of staff in wintry terrain.
Recording all important parameters of the snowpack
The SPA-2 system records automatically and continuously all important parameters of the snowpack and allows, for example, predictions about the snow melting progress. The latest product generation, the SPA-2, now offers a completely new and much more user-friendly control interface. Connecting analog sensors has become a lot easier, and the new standard for data outputs is realized via an RS-485 or SDI-12 interface.
Installation and measuring principle
The SPA-2 station can be operated autonomously (using solar power), and the mast and frame are set up in a suitable position on level ground. The weather- and UV-resistant sensor band penetrates the snow and measures the volumetric content of ice, water, and air in the snowpack using impedance analysis. The snow depth measurements are taken by our reliable ultrasonic snow depth sensor, the USH-8. Data storage and remote transmission equipment mounted in a weatherproof control cabinet can be provided additionally upon the customer’s request.
