Abstract
The utility model relates to a kind of Hall-type obliquity measurement sensor, comprises support (1), suspension rod (2), Hall element group (3), instrument amplifier (4); Suspension rod (2) upper end is suspended in support (1) top by hinge, can freely swing; Hall element group (3) comprises linear hall element I(3-1), linear hall element II(3-2) and permanent magnet (3-3); Permanent magnet (3-3) is fixed on the lower end of suspension rod (2), as pendulum; When the base level of support (1), linear hall element I(3-1), linear hall element II(3-2) export equal voltage, after instrument amplifier (4) amplifies, output voltage is zero; When support (1) base tilt time, linear hall element I(3-1), linear hall element II(3-2) output voltage unequal, through instrument amplifier (4) amplify after, output voltage is non-vanishing, by the value of output voltage can determine tilt angle.
Description
Technical field
The utility model relates to machinery, instrument and experimental study etc., particularly a kind of Hall-type obliquity measurement sensor.
Background technology
In construction work, mechanical engineering and laboratory, conventional level meter detects the horizontality of room thing, mechanized equipment or experimental apparatus, and conventional level meter is bubble type.Level is a kind of glass tube of sealing, and pipe built with the less liquid of the coefficient of viscosity, and leaves minute bubbles, carrys out determined level instrument whether level according to the position of bubble.Advantage is that structure is simple, and shortcoming is, temperature influence, read untrue, and can not determine the concrete angle of inclination.
Summary of the invention
For solving the deficiency of conventional level detection device, design a kind of Hall-type obliquity measurement sensor.This utility model comprises support (1), suspension rod (2), Hall element group (3), instrument amplifier (4); Suspension rod (2) upper end is suspended in support (1) top by hinge, can freely swing; Hall element group (3) comprises linear hall element I(3-1), linear hall element II(3-2) and permanent magnet (3-3); Permanent magnet (3-3) is fixed on the lower end of suspension rod (2), as pendulum; Linear hall element I(3-1), linear hall element II(3-2) output terminal be connected respectively to the positive and negative input end of instrument amplifier (4).Support (1) orthogonal frame, following base is rectangular surfaces, can put in the horizontal plane reposefully; The hard straight-bar that suspension rod (2) is made for nonmetallic materials, diameter is about 3mm.Linear hall element I(3-1), linear hall element II(3-2) be placed on the both sides of permanent magnet (3-3), when support (1) base level, linear hall element I(3-1), linear hall element II(3-2) equal to the distance of permanent magnet (3-3), and in the same horizontal line.Linear hall element I(3-1), linear hall element II(3-2) adopt model to be SL3503, instrument amplifier (4) adopt model be INA128.
The beneficial effect of this utility model is that structure is simple, and making aspect cost is low, is easy to digitizing.
Accompanying drawing explanation
Fig. 1 is utility model physical construction schematic diagram, and Fig. 2 is circuit theory diagrams;
In Fig. 1 and Fig. 2,1 be support, 2 be suspension rod, 3 be Hall element group, 4 for instrument amplifier; 3-1 is linear hall element I, 3-2 be linear hall element II, 3-3 is permanent magnet.
Embodiment
This utility model comprises support (1), suspension rod (2), Hall element group (3), instrument amplifier (4); Suspension rod (2) upper end is suspended in support (1) top by hinge, can freely swing; Hall element group (3) comprises linear hall element I(3-1), linear hall element II(3-2) and permanent magnet (3-3); Permanent magnet (3-3) is fixed on the lower end of suspension rod (2), as pendulum; Linear hall element I(3-1), linear hall element II(3-2) output terminal be connected respectively to the positive and negative input end of instrument amplifier (4).Support (1) orthogonal frame, following base is rectangular surfaces, can put in the horizontal plane reposefully; The hard straight-bar that suspension rod (2) is made for nonmetallic materials, diameter is about 3mm.Linear hall element I(3-1), linear hall element II(3-2) be placed on the both sides of permanent magnet (3-3), when support (1) base level, linear hall element I(3-1), linear hall element II(3-2) equal to the distance of permanent magnet (3-3), and in the same horizontal line.Linear hall element I(3-1), linear hall element II(3-2) adopt model to be SL3503, instrument amplifier (4) adopt model be INA128.
When the base level of support (1), linear hall element I(3-1), linear hall element II(3-2) export equal voltage, after instrument amplifier (4) amplifies, output voltage Vo is zero; When the base of support (1) is tilted to the left, linear hall element I(3-1) output voltage be greater than linear hall element II(3-2) output voltage, through instrument put device (4) amplify after output voltage be just; When the base of support (1) is tilted to the right, linear hall element I(3-1) output voltage be less than linear hall element II(3-2) output voltage, after instrument amplifier (4) amplifies, output voltage is negative; According to the output voltage size of instrument amplifier (4) and positive and negatively determine the angle whether base of support (1) tilts and tilt.
