Abstract: Inclination sensors with magnetic XMR- or Hall-sensor-principles were implemented in the past by the pivotably supported indicator magnet being supported on the front face of the axle of a pendulum, with the consequence that the static friction of the support had to be overcome first, before the inclination sensor would react. Thereby very small and very slow inclinations often could not be detected. These designs always have a large amount of hysteresis. According to the invention this problem is being solved by the indicator magnet being mounted either on a float, or on a pendulum that is being supported ferrofluidic, whereby the static friction is much smaller or eliminated entirely.

Abstract: The invention concerns position sensors, in particular their detector unit. The role of the existing invention is to simplify a position sensor of this construction principal so that function is guaranteed with sufficient accuracy, despite clearly lower production costs. It was determined that when using an electrically conductive waveguide, which simultaneously serves as an electrical conductor, with coaxial configuration of the detector coil directly on the electrical conductor and configuration of a corresponding shielding around the detector coil, in particular in the form of a flux-guide component, the information signal sufficiently differentiates itself from the existing interfering signal, in particular if the shielding surrounds the detector coil as tightly as possible.

Abstract: A rotation angle sensor is provided for determining mechanical angular positions and transposing them into signals transferable through electricity. The sensor includes a housing (2), a rotation indicator (4) located outside of the sensor housing (2a) so that it can rotate and coupled with the sensor element (3) so it operates in a non-contracting manner through the wall of the housing (2). A sensor element (3) is located in the interior of the housing (2). An intermediary element (5) is rotationally supported in the interior of the housing (2) between the sensor element (3) and the rotation indicator (4) and coupled to the rotation indicator (4) in a rotationally fixed, but non-contacting manner.

By locating the flat spiral spring within the interior of the cable drum, the construction length is reduced on one hand, and it becomes possible on the other hand to locate the cable outlet in one of the outer corners of the housing, which improves the application capabilities of the sensor.
