Abstract
Abstract The present invention provides an inclinometer comprising a supporting housing and a plumb member suspended within that supporting housing. The plumb member is provided on its exterior surface with a sensor, while the supporting housing is provided on its interior surface with a sensor co-operative with the sensor on the plumb member for determining exact upright positioning of the supporting housing. The inclinometer, as arranged above, is useable in many different apparatus, including an apparatus for maintaining a scientific and measuring instrument on a level plane.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
125 words
An inclinometer comprising a support housing and a plumb member freely suspended within said support housing, said support housing comprising an elongated hollow tube, said plumb member comprising an elongated body suspended within said elongated hollow tube, said elongated body being supported in a manner to prevent rotation thereof, said plumb member having an exterior surface provided with first sensing means and said support housing having an interior surface provided with second sensing means, said first and second sensing means comprising individual sensors opposing one another on said exterior surface of said plumb member and said interior surface of said supporting housing, said first and second sensing means cooperating to determine all different degrees of variation of said support housing from an exact upright position.
Claim 2
Dependent Claim
125 words
