Abstract
The utility model discloses a Hall direction sensor, comprising a magnetic steel, wherein the magnetic steel is arranged in a probe shell, an iron plate is arranged in front of the magnetic steel, and two Hall sensors are arranged at the front end of the iron plate; an alternating magnetic field signal is generated around the magnetic steel when a to-be-detected gear is rotated, and then conveyed to the iron plate, and the Hall sensors generate an alternating voltage under the action of the magnetic field change of the iron sheet; the alternating voltage is connected with the Hall sensors to output a forward-rotating phase signal when equipment is rotated forwards; and the alternating voltage is connected with the Hall sensors to output a reverse-rotating phase signal when the equipment is rotated reversely. Both speed and forward and reverse directions can be detected by using the Hall direction sensor provided by the utility model.
Description
Technical field
The utility model belongs to the technology of instrument and meter field, relates to a kind of sensor, particularly relates to a kind of Hall direction sensor.
Background technology
Test the speed and in control system, occupy critical role, can grasp the running speed of motor accurately, could better and safer carry out VSC; When speed fling lifting, take urgent measure immediately, prevent the generation of major accident, now market sensor commonly used can only detection speed, and both forward and reverse directions is also failed to detect.
The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art, and a kind of Hall direction sensor that can detection speed can detect both forward and reverse directions again is provided.
For achieving the above object, the technical scheme of the utility model provides a kind of Hall direction sensor, comprises magnet steel, and magnet steel is located at probing shell inside, is provided with iron plate in the front of magnet steel, and the front end of iron plate is provided with two hall sensors.
The course of work is: produce the alternating magnetic field signal when tested gear rotates around the magnet steel; And the alternating magnetic field signal is sent to iron plate; Hall sensor produces alternating voltage under the effect of iron plate changes of magnetic field; When equipment just changes, alternating voltage with just change hall sensor and connect output positive phase inversion position signal; When equipment reversed, alternating voltage connected output inverted phase signal with the counter-rotating hall sensor.
In order to guarantee the output of the utility model square-wave signal, further optimized technical scheme is that described iron plate and magnet steel are at least one.
Be destroyed for fear of interference or the utility model, further optimized technical scheme is, also comprises housing, and said magnet steel, iron plate, hall sensor all are arranged in the housing.
The advantage and the beneficial effect of the utility model are: the utility model provides a kind of sensor that can detection speed can detect both forward and reverse directions again; Since hall sensor be two each and every one, iron plate and magnet steel are at least one, can guarantee the output of the utility model reverse directions signal; Owing to also comprise that housing, said magnet steel, iron plate, hall sensor all are arranged in the housing, can avoid interference or the utility model is destroyed.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Like Fig. 1, shown in Figure 2, a kind of Hall direction sensor that the utility model provides comprises magnet steel 1, and magnet steel 1 is located at probing shell inside, is provided with iron plate 2 in the front of magnet steel, and the front end of iron plate 2 is provided with hall sensor a3 and hall sensor b4.
On the basis of embodiment 1, in order to guarantee the output of the utility model square-wave signal, further optimized technical scheme is, described iron plate 2 is at least one with magnet steel 1.
On the basis of embodiment 1, for fear of disturbing or the utility model is destroyed, further optimized technical scheme is, also comprises housing, and said magnet steel 1, iron plate 2, hall sensor a3 and hall sensor b4 all are arranged in the housing.
The utility model is installed simple, WV: DC12V, frequency: 0-20000Hz, measuring accuracy: 1 pulse, assemblage gap: 3.5mm-5.5mm
Be illustrated in figure 1 as the block diagram of the Hall direction sensor among the utility model embodiment.Adopt the power supply of DC12V power supply.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
