A capacitor that consists of four suitably spaced rings is considered for use as a reference standard and as the main element of a device for precise measurement of angle. In this capacitor, the mean of the two values of capacitance between the diagonally opposite rings is a second‐order function of random variations of ring spacing and shape. This property promises good stability and leads to simplified construction. When used for angle measurement, a ratio of two capacitances defines the angle. This makes variations of supply voltages, temperature, humidity, and pressure of lesser concern. Possible applications are in the fields of astronomy, geodesy, space technology, and precision mechanics.
