ABSTRACT:
An inclinometer 20 has a sensing unit 40 for providing a varying capacitance signal depending on the orientation of the inclinometer 20. An oscillator circuit unit 82 includes the sensor unit 40 as a capacitive element for providing a signal having a period and a frequency depending on the capacitance of the sensor unit 40. A unit 92 is provided for determining the period of the signal. A look-up table unit 96 stores a predetermined relationship between the period of the signal and the angle of orientation of the inclinometer 20. A comparison unit 94 then compares the period of the signal to the period stored in the look-up table unit 96 and selects the corresponding angle which is the angle of orientation of the inclinometer 20. The angle is then displayed on the inclinometer display 25.
