ABSTRACT:
A digital inclinometer for detecting the angular orientation of a structure includes a rotatable encoding disk on which is mounted a horizontal tilt sensor. The inclinometer electronically measures, by angular indices on the encoding disk, the difference between the angular orientation of the device and a horizontal orientation. In another embodiment, the encoding disk is rotated by a stepper motor and the number of steps are electronically counted to determine the angular orientation. The inclinometer has a digital display.
