摘要:
A flat scale indicating device for use with servo units having feedback loops, having an indicator arm pivotally mounted to a sector gear, the latter being in meshing engagement with a rotary pinion for transmitting rotary motion of the pinion to a straight line translatory motion at the pointer end of the indicating arm. The indicator arm further functions as a potentiometer wiper and an electrical connection is provided between the arm and a suitable amplifier bridge circuit.
摘要:
A linear variable capacitance transducer to monitor the axial position of an object by varying the capacitance of the transducer corresponding to the position of the object. When fed an AC signal, the position of the object being monitored corresponds to the proportional AC signal emitted therefrom.

A LINEAR VARIABLE CAPACITANCE TRANSDUCER HAVING AN AC CAPACITANCE SIGNAL PROPORTIONAL TO THE LINEAR DISPLACEMENT OF A THIN-WALLED METAL TUBE WHICH SLIDES WITHIN ANOTHER METAL TUBE TO PROVIDE A VARIABLE CAPACITANCE WITH THE AIR THEREBETWEEN AS THE DIELECTRIC.
摘要:
A variable capacitance transducer has a cable loop interlinked with a metallic tube. The cable loop comprises a metallic cablehalf joined to an insulative cable-half. The portion of the cable loop passing through the metallic tube is axially positioned in the tube and a capacitive element is formed by the metallic tube and the metallic cable-half. Displacement of the cable loop to vary the amount of the metallic cable-half inside the metallic tube varies the capacitance of the capacitive element in a linear manner.
