Abstract

The invention refers to a variable area capacitance digital parallel output-type angle displacement sensor, including; a capacitance measuring circuit of angle transformation capacitor, composed of variable frequency pulse generator, reverse-phaser, control and door circuit and 8-bit counter, and an angle displacement mechanical structure; the input and ground ends of the generator connect with capacity's stationary and active pieces, respectively; the sensor uses the angle displacement variable transmitted by the gear to make the relationship of variation of the capacitor piece's area and input angle displacement linear, and then uses the variation of the capacitance to find that of the angle displacement; the control and door circuit and 8-bit counter complete the conversion and transfer of different physical information.

Description

technical field [0001] The invention relates to a sensor, in particular to a variable-area capacitive digital parallel output angular displacement sensor used for indicating signal detection. Background technique [0002] The old type rudder position indicator of the aircraft can also be called "contact potentiometer type analog output type rudder angle displacement sensor", commonly known as "rotary potentiometer". The principle of the rotary potentiometer: When the cross-sectional area and resistivity of the ring resistance conductor are constant, its resistance value is proportional to the length of the resistance conductor. A movable mechanical compression spring brush is added to the circular resistance track, and the position of the brush on the circular resistance track is adjusted through the driving of the central axis, and the resistance value of the output terminal also changes with the angular displacement of the compression spring brush. Variety. [0003] The ...
