Abstract
The invention discloses a spring magnetometer which is composed of magnetic probes (1), springs (2) and indicators (3). The magnetic probes (1), the springs (2) and the indicators (3) are sequentially connected. One set of magnetic probes (1), the springs (2) and one indicator (3) can form a one-way spring magnetometer, or one or more magnetic probes (1), multiple springs (2) and multiple indicators (3) can form a two-way spring magnetometer and a three-way spring magnetometer. The two-way spring magnetometer and the three-way spring magnetometer are each provided with sensors (5) which are connected between the springs (2) and the digital indicators (3). When the magnetic probes are located in a magnetic environment, the springs are compressed or stretched and dragged under the acting force of a magnetic field, deformation generated by the springs are directly transmitted to the indicators, and the indicators display the magnitude of the deformation, namely the magnitude of magnetic force.
Description
Technical field
The present invention relates to a kind of measurement indicating device of magnetic force, belong to measurement instrument field.
Background technology
Around heavy DC electricity, stronger magnetic induction density can be produced.As around aluminium cell because magnetic induction density is comparatively large, the exception of relevant device, operation can be caused; When carrying out welding operation to electrolytic tank steel construction and aluminium busbar etc., due to affected by magnetic fields, cannot welding in series energising situation, must series have a power failure after just can carry out welding operation.
Therefore, the magnetic induction density of measuring target point and the size of magnetic field force, have important directive significance to practical operation exactly.
Measurement now to magnetic field, mostly adopt gaussmeter or teslameter, the instrument of its measurement magnetic induction density made according to Hall effect principle, it is made up of hall probe and measurement instrument.Hall probe produces Hall voltage because of Hall effect in magnetic field, can determine the size of magnetic induction density after measuring Hall voltage according to Hall voltage formula and known Hall coefficient.
But the working site had, it is understood that the electromagnetic force size produced the ferromagnetic material that is in wherein produced due to magnetic induction density, needs the calculating of specialty according to gaussmeter then can not obtain the value of electromagnetic force.
The present invention produces the principle of acting force to the magnet put into wherein according to magnetic field, provide a kind of easy mgnetic observations device.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of structure simple spring magnetometer, to overcome the complex structure that prior art exists or the deficiency being difficult to obtain electromagnetism force value.
Technical scheme of the present invention is: spring magnetometer is made up of magnetic force probe, spring and indicator; Magnetic force probe, spring are connected successively with indicator; Unidirectional spring magnetometer can be formed by one group of magnetic force probe, spring and indicator, also can form double-acting spring magnetic force by one or more magnetic force probe, multiple spring and multiple indicator and take into account three-dimensional spring magnetometer.
Indicator is pointer-type indicator, or is digital indicator.
Indicator is pointer-type indicator, and this pointer-type indicator covers on outside spring, and is provided with pointer.
Double-acting spring magnetometer and three-dimensional spring magnetometer are provided with sensor, and sensor is connected between spring and digital indicator.
When the present invention works, magnetic force probe be connected with spring, when magnetic force probe is in magnetic environment, is subject to the acting force in magnetic field and produces compression or stretching and drawing to spring; The deformation that spring produces is directly delivered on indicator, and by the size of indicator for displaying deformation, namely shows the size of magnetic force.Compared with the measurement mechanisms such as the gaussmeter of prior art, according to measured spring deformation, can directly judge the size of electromagnetic force, the power in magnetic field.
