Abstract: An inclination gauge that includes a bar placeable against a surface to be gauged to determine the degree to which the surface is inclined with respect to the horizontal or vertical. Mounted on the bar is a gravity-sensing potentiometer coupled to a balancing circuit to produce an analog output voltage which has a null value when the bar is placed against a perfectly horizontal or vertical surface and which has a magnitude and polarity or phase that depends on the extent and direction of the deviation from the norm when the surface being gauged is inclined. The analog voltage is converted into a corresponding digital value that is applied to a digital display.

Abstract: An inclination gauge that includes a bar placeable against a surface to be gauged to determine the degree to which the surface is inclined with respect to the horizontal or vertical axis and to provide a readout in digital as well as in analog terms. Mounted on the bar is a gravity-sensing potentiometer coupled to a balancing circuit to produce an analog output voltage which has a null value when the bar is placed against a horizontal or vertical surface and which has a magnitude and polarity or phase that depends on the extent and direction of the deviation from the norm when the surface being gauged is inclined. The analog voltage is converted into a corresponding digital value that is applied to a digital display. Also mounted on the bar are conventional spirit level tubes, one being arranged for horizontal and the other for vertical gauging.
