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.

An inclination sensor, said sensor comprising:
- a housing (2) with a float chamber (4) with a divider wall (6) made from non-magnetic material;
- an indicator magnet (8) located in the float chamber (4) moveable directly or indirectly according to gravity;
- a magnetosenstitive sensor (9) outside of the float chamber (4);
- and
- wherein the indicator magnet (8) is disposed on a float (5, 5′) that floats on a fluid (7) located in the float chamber 4.
An inclination sensor, said sensor comprising:
- a housing (2) with a chamber (4) having one wall (6) made from a material that cannot be magnetized;
- an indicator magnet (8) movable directly or indirectly according to gravity in the chamber (4);
- a magnetosensitive sensor (9) outside of the chamber (4);
- and
- wherein the indicator magnet (8) is disposed torque proof on a pivot axis (10) of a pendulum (25), which is supported ferrofluidic, with its pole axis (15) disposed transversal to the pivot axis (10).
