Title: INTEGRAL POSITIONING AND INDICATING DEVICE

Abstract

A variable capacitor which may be used as an integral positioning and indicating device is descried. The apparatus comprises a hollow metal cylinder with a metal rod mounted fixedly along the axis thereof and insulated therefrom. A hollow shaft is slidably mounted between the cylinder and the rod in electrical connection with the cylinder and insulated from the rod. One end of the shaft is disposed between the cylinder and the rod and the other end extends therefrom and may be connected to an object whose position is to be monitored. Means are provided to move the hollow shaft by pressure fluid in the cylinder whereby the capacitance between the rod and the cylinder is varied and measurement of which is a function of the position of the hollow shaft.
