Description
Technical field
The utility model relates to a kind of signal feedback device, especially relates to a kind of position feedback device for atmospheric control.
Background technology
At present, feedback control system is the key link that equipment is realized robotization control, has very important status in modern control technology.Feedback control system is the automatic control system of setting up based on feedback principle, so-called feedback principle is exactly to control according to the information of system exporting change, by the deviation between the actual output of comparison system and expectation value, control accordingly, and eliminate deviation, reach the result of expecting in advance.Do not have the equipment of feedback control system usually can not be according to predefined rule work, the reliability and stability of its work be not fully up to expectations.
Summary of the invention
The purpose of this utility model is to overcome the weak point existing in above-mentioned technology, provide a kind of simple in structure, reasonable in design, easy for installation, can realize switching value indication and analog signal output that full switch puts in place, and for the position feedback device of atmospheric control.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise lid, box body, lid outside has long cable section of ingoing line hole and shaft, lid inside left is equipped with connection terminal, and there is sensory package at lid central interior position, and lid inner right side is equipped with to become send output board, described lid and box body are fixed by lid gib screw, described shaft is connected with sensory package, and described sensory package send output board to be connected with change, and described change send output board to be connected with connection terminal.
The utility model has the advantages that:
Simple in structure, reasonable in design, easy to install and use, can meet the requirement of various atmospheric control signal feedback, highly versatile, can be in operational process feedback device running status, improve equipment reliability of operation and stability.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is sensory package and becomes the connection diagram of sending output board.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
From Fig. 1-Fig. 2, the utility model comprises lid 2, box body 4, lid 2 outsides have long cable section of ingoing line hole 1 and shaft 5, lid 2 inside left are equipped with connection terminal 6, and there is sensory package 7 at lid 2 central interior positions, and lid 2 inner right side are equipped with to become send output board 8, described lid 2 is fixing by lid gib screw 3 with box body 4, described shaft 5 is connected with sensory package 7, and described sensory package 7 send output board 8 to be connected with change, and described change send output board 8 to be connected with connection terminal 6.
It puts angular displacement feedback dress of the present utility model, comprise lid 2, box body 4, box body 2 outsides are equipped with long cable section of ingoing line hole 1 and shaft 5, box body 2 inside left are equipped with connection terminal 6, and box body 2 central interior are equipped with sensory package 7, and box body 2 inner right side are equipped with to become send output board 8, lid 2 is fixing by lid gib screw 3 with box body 4, shaft 5 is connected with sensory package 7, and sensory package 7 send output board 8 to be connected with change, becomes and send output board 8 to be connected with connection terminal 6.Angular displacement feedback assembly of the present utility model, by shaft 5 and equipment connection, the angular displacement signal of equipment is through shaft 5 entering angle Displacement Feedback devices, after the angular displacement signal processing of equipment being processed by sensory package 7, send to become and send output board 8, signal send output board 8 to pass to connection point terminal 6 by wire by change, signal is passed in the cable that extracts signal through long cable section of ingoing line hole 1 by connection terminal 6, so angular displacement signal can be fed back, can reach by the object of feedback signal checkout equipment running status.
