NON-CONTACT TYPE TWO CHANNEL ROTATION DISPLACEMENT SENSOR WITH LOW CURRENT CONSUMPTION FOR PRECISELY MEASURING MAGNETIC FORCE IN TWO POSITIONS BY ELIMINATING UNBALANCE OF MAGNETIC FORCE

摘要

PURPOSE: A non-contact type two channel rotation displacement sensor with low current consumption is provided to precisely measure a magnetic force in two positions according to a rotation of a rotation body by removing unbalance of a magnetic force caused by eccentricity of the rotation body. CONSTITUTION: A non-contact type two channel rotation displacement sensor includes a housing(30) forming a placing seat(32) at a bottom surface thereof. A cover(20) is provided to cover the housing(30). The cover(20) includes a sensor mounting hole(22) and a penetrating hole(24). One end of a rotation body(40) is placed at the placing seat(32) of the housing(30). A coupling flange(44) formed at a middle portion of the rotation body(40) is coupled to a peripheral portion of the penetrating hole(24) of the cover(20) in order to rotatively support the rotation body(40) in the housing(30). A coupling hole(42a) is formed at an upper end of the rotation body(40).
