The present invention describes an electronic device (2) and corresponding method for monitoring hydrogeological phenomena, in particular the integrity of a rockfall protection barrier by detecting mechanical load exceeding a threshold, such as due to impact or debris flow. The device is provided with elongated flexible “legs” protruding from the housing in a radial manner and connected to a surface to be monitored (i.e. rockfall net) for detecting mechanical stress.

An object press performance measuring system for measuring a pressure value of an object to be measure includes a measuring unit and an elastic assembly. The elastic assembly is disposed between the object to be measured and the measuring unit. The elastic assembly has a first assembly and a second assembly, wherein the second assembly is disposed between the first assembly and the measuring unit and the first assembly performs a first measuring travel of the object to be measured and the second assembly performs a second measuring travel of the object to be measured, wherein the second measuring travel refers to measure the pressure value greater than the pressure measured in the first measuring travel.

A force sensing element is used in a pressure transducer. The force sensing element includes a flat, disc-type spring having a unitary body that circumscribes a central axis, and a plurality of spirals that are continuous with each other and extend radially outwardly from the central axis. The plurality of spirals includes nested symmetrical flights having walls with a non-uniform thickness, and the disc spring is uniformly deflectable along the central axis in response to force acting on the disc-type spring. The spring is configured to have a high accuracy and a high fatigue life such that the spring is suitable for use in high-pressure applications that may require repeatability while operating with over 10 million cycles of unidirectional or bi-directional axial loading.
