The utility model discloses a linear displacement sensor. The linear displacement sensor comprises a housing, a connecting rod, a signal line, a spring and a precision sliding resistor. The connecting rod goes through the housing, one end of the connecting rod is connected with a sliding tap of the precision resistor, the spring is sleeved on the connecting rod, a circuit board is disposed in the housing, the precision sliding resistor is arranged on the circuit board, and the signal line is arranged at a rear part of the housing. Through the manner, the linear displacement sensor has the advantages of high reliability, accurate positioning, compact structure, long service life, low price and the like.
Description
Technical field
The utility model relates to sensor field, particularly relates to a kind of linear displacement transducer.
Background technology
The action need mechanical trip feedback that has a large amount of forging and stamping isoline motions in commercial production, common servo unit cannot be applicable to these projects, therefore straight-line displacement sensing is often installed on hydraulically operated equipment (HOE) monitors producing, general linear displacement transducer structure is comparatively complicated, cost is higher, and the life-span is shorter.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of linear displacement transducer, by resistance variations, realize the measurement of displacement, by the variation of voltage signal, realize the output of sensor, have that reliability is high, a registration, compact conformation, long service life, the advantage such as cheap.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of linear displacement transducer is provided, comprise: shell, connecting rod, signal wire, spring and accurate swept resistance, connecting rod passes through shell, connecting rod one end is connected with precision resistance sliding tap, and spring housing, on connecting rod, is provided with wiring board in shell, in the circuit board, signal wire is arranged on shell rear portion in accurate swept resistance setting.
In preferred embodiment of the utility model, in described shell, be provided with wiring board installation position and spring position block.
In preferred embodiment of the utility model, described connecting rod is provided with spring set collar.
In preferred embodiment of the utility model, connecting rod front end is provided with screw thread, and rear end has connecting hole.
The beneficial effects of the utility model are: the utility model linear displacement transducer is realized the measurement of displacement by resistance variations, by the variation of voltage signal, realize the output of sensor, have that reliability is high, registration, compact conformation, long service life, the advantage such as cheap.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of the utility model linear displacement transducer one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, shell, 2, spring, 3, connecting rod, 4, accurate swept resistance, 5, screw thread, 6, wiring board, 7, signal wire, 8, spring position block, 9, mounting hole.
Embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of linear displacement transducer, comprise: shell 1, connecting rod 3, signal wire 7, spring 2 and accurate swept resistance 4, connecting rod 3 is by shell 1, connecting rod 3 one end are connected with precision resistance sliding tap, spring 2 is enclosed within on connecting rod, in shell 1, be provided with wiring board 6, accurate swept resistance 4 arranges in the circuit board, and signal wire 7 is arranged on shell 1 rear portion.
In described shell 1, be provided with wiring board installation position and spring position block 8, facilitate core component to fix and install back-moving spring.
Described connecting rod 3 is provided with spring set collar, and fixing spring is eliminated return difference.
Described connecting rod 3 front ends are provided with screw thread, and rear end has connecting hole, for the reliable connection of external agency and resistance.
The course of work of sensor is:
After the connecting rod of linear displacement transducer is pushed, make it promote the tap of swept resistance, resistance is changed, the voltage recording at connecting line also changes, easily the displacement of calculating sensor.
The beneficial effect of the utility model linear displacement transducer is:
One, by spring is set, eliminate the motion return difference of sensor, reduce sensor error;
Two,, by using long-life accurate swept resistance, have that reliability is high, a good linearity, feature that measuring accuracy is high;
Three, this utility model sensor construction is compact, and reliability is high, with low cost, and measuring accuracy is higher, long service life.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
