Abstract
The utility model discloses a magnetic-sensing synchronous digital displacement sensor, the main structure of which comprises a stainless steel tube, a slipping bush arranged on the stainless steel tube, a printed circuit board arranged inside the stainless steel tube, magnetic-sensing switching elements are uniformly allocated on the printed circuit board, an I/O port element is also arranged on the printed circuit board. The I/O port element is connected with a microprocessor. As a detecting circuit of the microprocessor being matched with the I/O port element and magnetic-sensing switching elements is adopted, the sensor has correct position without drift, good mechanism performance, and is capable of outputting digital signals, with strong anti-interference ability, high measuring precision and accuracy and long service life.
Description
Technical field
The utility model relates to a kind of sensor, particularly a kind of magnetosensitive synchronous digital displacement transducer that can be used in particular surroundings.
Background technology
Common displacement transducer has reed switch relay, inductive displacement transducer, potentiometric displacement transducer etc., and reed switch relay generally is to adopt contact switch, and it is a kind of detection that puts in place, and the accuracy of detection position is lower, and serviceable life is short; Inductive displacement transducer, its output signal be simulating signal and signal a little less than, antijamming capability is not strong, and is higher to power requirement, interchangeability is bad, the processing of output signal is more complicated also; Potentiometric displacement transducer is had relatively high expectations to water-proofing treatment, and drive disk assembly often needs lubricated maintenance, its output be simulating signal, do interference performance a little less than, the numerical value instability.
Summary of the invention
It is simple in structure that the purpose of this utility model will provide exactly, and long service life can provide digital signal, and the precision height can be applicable to all-environment magnetosensitive synchronous digital displacement transducer.
The purpose of this utility model is achieved in that a kind of magnetosensitive synchronous digital displacement transducer, comprise stainless-steel tube 2, slip ring 1 is enclosed within on the stainless-steel tube 2, be provided with printed circuit board (PCB) 3 in the stainless-steel tube 2, magnetosensitive on-off element 4 is divided equally on printed circuit board (PCB) 3, also is provided with I/O mouth element 6 on the printed circuit board (PCB) 3.I/O mouth element 6 is connected with microprocessor 7.
Magnetosensitive synchronous digital displacement transducer provided by the utility model, because the testing circuit that has adopted microprocessor to match with I/O mouth element and magnetosensitive on-off element, its position is accurate, there is not drift, good mechanical property can be exported digital signal, and antijamming capability is strong, measuring accuracy and accuracy height, long service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
Structure of the present utility model as shown in Figure 1, a kind of magnetosensitive synchronous digital displacement transducer comprises stainless-steel tube 2, slip ring 1 is enclosed within on the stainless-steel tube 2, be provided with printed circuit board (PCB) 3 in the stainless-steel tube 2, magnetosensitive on-off element 4 is divided equally on printed circuit board (PCB) 3, also is provided with I/O mouth element 6 on the printed circuit board (PCB) 3.I/O mouth element 6 is connected with microprocessor 7.
Principle of work of the present utility model is: magnetosensitive on-off element 4 is evenly distributed on the printed circuit board (PCB) 3 of corresponding shift length, forms a position probing display, with the several I/O mouths of parallel input string line output I/O mouth element 6 expansions.The corresponding magnetosensitive on-off element 4 of each I/O mouth, promptly each I/O mouth is represented definite, a unique position.The I/O mouth has two states, i.e. high level and low level, and the switch of the every element 4 of magnetic causes the state of I/O mouth to change.When every survey thing drove slip ring 1 motion of sensor, slip ring 1 moved on the stainless-steel tube 2 of sensor, triggers the every element 4 of corresponding magnetic, reads the state of I/O mouth by microprocessor, thereby determines its position.Sensor can adopt epoxy casting, is particularly suitable for the application circumstances of hydroelectric power plant.
Magneto sensor 4 in this device can be Hall element, magnetic switch etc.
