Abstract
Disclosed is an improved inclination sensor and an improved inclinometer. A pair of plates in combination with a metallic housing provides accurate inclination information over ranges of 0.degree..+-.60.degree. and 180.degree..+-.60.degree.. A second pair of plates rotated 90.degree. in the plane of the first pair of plates, provides accurate inclination information over ranges of 90.degree..+-.60.degree. to 270.degree..+-.60.degree.. Coverage is thereby provided over 360.degree.. The inclination sensor is combined with a microprocessor which is programmed to weight the contribution of the plates so as to provide a smooth transition for angles in the region of coverage overlap. A EEPROM memory stores and provides calibration input information to correct the inclination sensor output to accurate output angles.
