Sensors measuring separation distance

In the early 1980s, Josef Frauscher developed the "analogue sensor". This is an inductive sensor system that measures the separation distance of a metal part and provides the information in the form of an injected analogue current.

Initial applications were realised in retaining walls for power stations, where these sensors detect the structure's deviation from the vertical. Frauscher analogue sensors are manufactured for a range of applications, such as to determine the location of switch blades, to monitor retaining walls, to display levels, etc.
