Abstract
The utility model relates to a straight line/angle displacement sensor, which comprises a casing, a moving axis inputting straight line/angle displacement with mechanical quantity. The utility model is characterized in that the moving axis of the sensor is an axis inlaid with magnetic steel; a stator is a chip positioned at the outer edge of the same plane with magnetic steel moving axis; the chip is arranged on the cylinder wall of the column-shaped cylinder casing; the magnetic steel and the chip are not contacted and have a gap; the chip is connected with an electric quantity output line. The main working components in the sensor achieves real non-contact; the utility model realizes no abrasion in the process of working, does not influence on working precision for a long time, and extends the service life of elements.
Description
One, technical field:
The utility model relates to a kind of sensor, particularly discloses a kind of straight line/angular displacement sensor, is applied in the automatic control system.
Two, background technology:
As everyone knows, in automatic control system, the automatic component kind of reflection straight line/angular displacement is a lot, for example linear potentiometers, selsyn, rotary transformer or the like, some automatic elements, become by displacement signal that there is the contact device in majority in the electric signal process, make these automatic elements have product wearing and tearing in the use, influence precision and life-span.
Three, summary of the invention:
Technical problem to be solved in the utility model is to disclose a kind of straight line/angular displacement sensor, make the main working parts of sensor internal reach truly noncontact, can realize that the course of work do not have wearing and tearing, not influence operating accuracy for a long time, improve the serviceable life of element.
The utility model is to realize like this, straight line/angular displacement sensor, comprise the moving axis of sensor housing and mechanical quantity input straight line/angular displacement and the stator of electric weight output displacement, it is characterized in that: rotor sensor is the rotating shaft that is inlaid with magnet steel, stator is to be positioned at the same plane of magnet steel moving axis outer rim, and be installed in chip on the pillar buoy housing barrel, magnet steel and chip noncontact have the gap, chip is associated with the electric weight outlet line, the angular displacement sensor of said structure, inner main service part has reached noncontact truly, serviceable life and operating accuracy have effectively been improved, sensor changes into the variation of the DC voltage on the chip with the variation of displacement signal through magnetic field, the DC voltage of the chip V ∞ ksin α that is directly proportional with magnet steel magnetic direction angle.
Four, description of drawings:
Accompanying drawing 1 is the utility model angular displacement sensor structure figure
Accompanying drawing 3 is the utility model linear displacement transducer structural drawing
Five, embodiment:
With reference to the accompanying drawings 1, angular displacement sensor comprises sensor housing 1, the moving axis 2 in pillar buoy housing axle center is thick in the middle of cylinder shell, the housing at two cooperates section thin, bearing 6 is equipped with in the cooperation place, inlays magnet steel 3 in the rotating shaft in the housing, and the size of magnet steel is decided according to job requirement, stator is the chip 4 that is positioned at the same plane of magnet steel moving axis outer rim, chip is installed on the pillar buoy housing barrel, and there are the gap in magnet steel and chip noncontact, and chip is connected with electric weight outlet line 5.
Linear displacement transducer structure and principle are similar in appearance to angular displacement sensor, only moving axis becomes linear reciprocation by rotation and moves, the same angular displacement sensor of part sequence number title, but be provided with back-moving spring 7 under the moving axis 2, do not fuse so that have relative motion floating ground and measured piece, and do not have rigid connector, centering is installed conveniently, also moving axis and measured piece rigidity can be fused, but require to install strictness of centering.
Claims (4)
1, a kind of straight line/angular displacement sensor, comprise the moving axis of housing and mechanical quantity input angular displacement and the stator of electric weight angle displacement, it is characterized in that: rotor sensor is the rotating shaft that is inlaid with magnet steel, stator is the chip that is positioned at the same plane of magnet steel moving axis outer rim, chip is installed on the pillar buoy housing barrel, magnet steel and chip noncontact have the gap, and chip is associated with the electric weight outlet line.
