Description
Technical field
The utility model belongs to electronic component field of measuring technique, and in particular to a kind of Hall element sensitivity measure dress
Put.
Background technology
Hall element is a kind of Magnetic Sensor based on Hall effect, easy to use because of its small volume, accuracy of measurement
Height, the advantages that measurable AC and DC magnetic field, be widely used in the measurement in magnetic field, and be equipped with other devices be used for position, displacement,
The measurement of the physics such as rotating speed, angle and automatically control.The sensitivity of Hall element is directly connected to the occasion and mode of its application,
It is a critical component parameter.Typically under some operating voltage or electric current, the voltage or electric current of Hall element output
It can change with the change of induction level, the output voltage or electric current changed with the change of unit magnetic induction intensity is i.e.
The referred to as sensitivity of the Hall element.
The content of the invention
The purpose of this utility model is to provide a kind of measurement apparatus for determining Hall element sensitivity with electromagnet.The dress
Putting can be placed in Hall element to be measured in variable magnetic field, and its output electricity is measured while providing power supply for Hall element to be measured
Pressure or electric current, so as to obtain its sensitivity.
Hall element sensitivity measuring apparatus provided by the utility model, including：Electromagnet 1, gaussmeter 2, adjustable electric
Source 3 and voltage/current table 4；Wherein：
The electromagnet 1 is c-type, and two magnetic poles is relative planes and are parallel to each other, magnetic pole Jian You field homogeneities area, electromagnetism
Induction is adjustable；
The inductive head of the gaussmeter 2 is arranged at field homogeneity area, for indicating the magnetic strength between magnetic pole in field homogeneity area
Answer intensity；
The regulated power supply 3 connects with Hall element voltage to be measured or current input terminal, provides and is less than for Hall element
Equal to its specified operating voltage or electric current；
The voltage/current table 4 connects with Hall element voltage to be measured or current output terminal, for measuring Hall element
Output voltage or electric current.
When the utility model measures, Hall element to be measured is placed in the field homogeneity area between electromagnet pole, it is opposite
The detecting head of gaussmeter；Regulated power supply is connected by wire and is connected with Hall element voltage or current input terminal, to provide work
Power supply；Voltage/current table is connected by wire with Hall element output end, to measure output voltage or electric current.By changing electricity
The size of current of magnet coil changes the magnetic induction intensity between magnetic pole, and the knots modification of magnetic induction intensity is measured with gaussmeter, with
Voltage/current table measures the output voltage or electric current of Hall element, so as to obtain Hall element to be measured with unit magnetic induction intensity
The change output voltage or electric current that are changed, i.e. its sensitivity.
The utility model is simple in construction, and testing efficiency is high, and test result is accurate.
Brief description of the drawings
Fig. 1 is exterior structure figure of the present utility model.
Label in figure：1 is electromagnet, and 2 be gaussmeter, and 3 be regulated power supply, and 4 be voltage/current table.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
In Fig. 1, the magnetic field that the detecting head of Hall element to be measured and gaussmeter 2 is collectively disposed between the magnetic pole of electromagnet 1 is equal
In even area, the magnetic induction intensity magnetic pole can be adjusted by the power supply of regulating magnet 1, in field homogeneity area, magnetic
Induction may be considered identical everywhere, and the size of the magnetic induction intensity is measured and shown by gaussmeter 2.Regulated power supply
3 provide operating voltage or electric current by wire for Hall element to be measured, and the voltage of Hall element to be measured or electric current export
End is then connected to voltage/current table 4 by wire, so as to be able to record the measured value of its output voltage or electric current.
