Remote Measuring-, Warning and Alarming Systems


AlpuG designs, builds and services together with its partners Waljag, Sensalpin and IAV remote instrumentation for data acquisition, data logging, data transmission and control applications to assess alpine natural dangers. The systems are designed to measure and investigate processes related to possible natural dangers do to avalanching, rockfall, mudflow, flooding, melting permafrost and to alert and alarm automatically in case of increased danger.

A physically correct and dependable measurement of meteorological and nivological parameters builds the basis for critical decisions and new knowledge. Our measuring and control systems that are specially optimized for remote locations and harsh environmental conditions are a proven starting point for successful solutions. The wide range of sensors and interfaces that can be connected and controlled by our systems, the well developed and standardized mechanical platforms, proven concepts for energy supply, overvoltage protection, communication and data acquisition allow for designs that are perfectly adapted to the problem.

Measurements and concepts

For successful measurements it is important to understand the physical principles of sensing as well as the processes to be characterized or investigated by the measurements. Our experience in the field of alpine natural danger allows us to find best suited solutions for your measuring problem. Our systems are based on Campbell Scientific data loggers and a large variety of specially adapted sensors and interfaces.







Mechanical supporting systems, towers.

We offer different supporting platforms depending on size and requirements of the measuring system to be mounted. The larger system based on a 6.5m long 219mm diameter pylon is anchored on 3 micropiles or rock anchors or may be directly mounted to vertical rock walls (pdf22). It includes a very compact and flexible platform for sensors, electronics, transmission antennas and the solar system that can be fitted to the tower completely assembled and in operation by helicopter within minutes but can also be lowered to ground level for local servicing. For smaller measuring systems with pylons up to 5m ( diameter 80mm) an universal anchor system is available (pdf13, pdf18). This portable anchor system is very flexible and can be mounted on rock or buried in softer or loose ground. No guying cables are needed for this system.
For both systems many standard clamps for sensors, panels, antenna, mounting arms exist. Special systems have also be designed for measurements on glaciers.
