The part of welding, possesses moistureproof, mould proof, Defend salt fog, dust-proof, antistatic, the performance of insulation.
By the setting to Hall sensor 41, make the output signal of Hall sensor 41, both can be analog signalses,
Such as current signal, voltage signal etc., or digital quantity signal, such as SER signal, SSI signals etc., and hall sensing
The output signal of device 41 is revisable.
A kind of straight-line displacement potentiometer of the invention, according to the position of main shaft 2, exports corresponding by Hall sensor 41
Output signal, the function is mainly realized by Hall sensor 41 and magnet steel 32.
Hall sensor 41 can by non-contacting form detect magnet steel 32 produced by magnetic field on three-dimensional magnetic strength
The change of intensity is answered, magnet steel 32 is gone out by the change calculations of the angle theta between the quadrature component and Hall sensor 41 in the magnetic field
Current angle position or linear position.
In implementation process, two main difficult points are：First, magnet steel 32 enters water-filling along the axial direction of magnetic screen shell 1
During straight displacement of the lines, its produce magnetic field quadrature component and Hall sensor 41 between angle theta, Hall sensor 41 it is defeated
Go out the amplitude of signal, between the two in non-linear relation；Second, the straight-line displacement amount L of magnet steel 32, the magnetic field that magnet steel 32 is produced
Angle theta between quadrature component and Hall sensor 41, between the two in non-linear relation.
To solve above-mentioned difficult point, debugging is programmed by Hall sensor 41, believes the output of Hall sensor 41
Number meet specific characteristic curve, its general principle is shown in Fig. 7.
In implementation process, need to confirm the straight-line displacement scope of magnet steel 32, orthogonal point of the magnetic field that magnet steel 32 is produced first
The span of the angle theta between amount and Hall sensor 41.Secondly, the quadrature component and suddenly in the magnetic field for being produced according to magnet steel 32
The span of the angle theta between your sensor 41, choosing magnet steel 32 carries out the working range of horizontal linear displacement, and sets institute
State in working range, the upper and lower bound of the amplitude of the output signal of Hall sensor 41.The magnetic field that now magnet steel 32 is produced is just
Hand over the angle theta between component and Hall sensor 41, the amplitude of the output signal of Hall sensor 41, between the two in non-linear
Relation.
The working range that magnet steel 32 carries out horizontal linear displacement is split, each cut-point in the working range
And two end points of the working range, the output signal of Hall sensor 41 has corresponding feature amplitude, by setting
The feature amplitude of the output signal of Hall sensor 41, any two adjacent segmentation point at interior each cut-point of the working range
Between, the equal approximately linear of amplitude of the output signal of Hall sensor 41 is distributed, therefore the output signal of Hall sensor 41 has
The characteristics of thering is multistage linear to be distributed.By above-mentioned means, Hall sensor 41 can be made according to output signal in the working range
Amplitude upper and lower bound, and the output signal in the working range at each cut-point feature amplitude, Yi Jisuo

Each Along ent at, the output signal of Hall sensor 41 has corresponding feature amplitude, adjusts in the working range
The feature amplitude of the output signal of Hall sensor 41 at each Along ent so that the output signal of Hall sensor 41 it is continuous and
With multistage linear, be finally distributed the amplitude approximately linear of the output signal of Hall sensor 41, Hall sensor 41 it is defeated
Go out signal for linear signal, the feature amplitude at two end points of the working range corresponds to the output letter of Hall sensor 41
Number amplitude upper and lower bound, as shown in Figure 9.Therefore, the output signal of Hall sensor 41 is linear signal, the linear letter
Number amplitude can be with monotonic increase, it is also possible to monotone decreasing, and reach expected linear precision.
When a kind of straight-line displacement potentiometer of the invention works, the magnetic field that Hall sensor 41 is placed in the generation of magnet steel 32 is empty
Interior, as main shaft 2 carries out horizontal linear displacement with movable slider 31 and magnet steel 32, Hall sensor 41 detects X-axis, i.e., with master
The axially in parallel direction of axle 2, and Z axis, i.e. vertical direction, the change of magnetic field intensity in both direction, this change pass through Hall
The setting of sensor 41 is converted into the analog signalses for needing or digital quantity signal is exported, and obtains output signal.Output letter
Number can be for pwm signal, SPI signal or SSI signals etc., external equipment reaches straight line position by gathering above-mentioned output signal
Move the purpose of detection.
A kind of beneficial effect of straight-line displacement potentiometer of the invention is, by the contact of traditional line floatingpotential device
Working method is changed to using the non-contact operation mode of Hall effect, it is to avoid the essence caused by abrasion between brush and resistive element
Degree change, extends the working life of straight-line displacement potentiometer.Simultaneously when the output signal of Hall sensor 41 is linear signal
When, a kind of straight-line displacement potentiometer of the invention has more preferable linear precision.Simultaneously can also be by Hall sensor 41
Pre-programmed, increase the species of the output signal that a kind of straight-line displacement potentiometer of the invention can be output, in same length magnetic
In shielding shell 1, the measurement of various impulse strokes is realized, reduce the cost of product.
Meanwhile, a kind of straight-line displacement potentiometer of the invention is also equipped with the support 16 for fixing magnetic screen shell 1.
