Abstract
The utility model discloses a magnetometer composed of magnetic force probes (1), springs (2) and an indicator (3). The magnetic force probes (1), the springs (2) and the indicator (3) are sequentially connected. One magnetic force probe (2), one spring (2) and one indicator (3) together form a unidirectional spring magnetometer; otherwise, one or more magnetic force probes (1), more than one springs (2) and more than one indicator (3) can form a bidirectional spring magnetometer and a three-way spring magnetometer. Sensors are arranged on the bidirectional spring magnetometer and the three-way spring magnetometer. The sensors (5) are connected between the springs (2) and the digital indicator (3). When the magnetic force probe is in a magnetic environment, the magnetic force probe is under an active force of a magnetic field so as to exert compression or stretching traction effects on the springs. Deformation occurring to the springs can be directly transmitted to the indicator, and the indicator displays the magnitude of the deformation. The displayed magnitude of the deformation is the magnitude of the magnetic force.
Description
Technical field
The utility model relates to a kind of magnetic force measurement indicating device, belongs to measurement instrument field.
Background technology
Around heavy DC electricity, can produce stronger magnetic induction density.If aluminium cell is around because magnetic induction density is larger, can cause the abnormal of relevant device, operation; In the time that electrolytic tank steel construction and aluminium busbar etc. are carried out to welding operation, due to affected by magnetic fields, cannot welding in series energising situation, after must series having a power failure, 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 to magnetic field, adopts gaussmeter or teslameter mostly now, the instrument of its measurement magnetic induction density of making according to Hall effect principle, and it is made up of hall probe and measurement instrument.Hall probe because Hall effect produces Hall voltage, is measured after Hall voltage the size that can determine magnetic induction density according to Hall voltage formula and known Hall coefficient in magnetic field.
But in the working site having, what need to know is the electromagnetic force size that the ferromagnetic material in is wherein produced producing due to magnetic induction density, needs professional calculating if adopt gaussmeter can not obtain the value of electromagnetic force.
The utility model to putting into the principle of magnet generation acting force wherein, provides a kind of easy mgnetic observations device according to magnetic field.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of magnetometer simple in structure, to overcome the complex structure that prior art exists or the deficiency that is difficult to obtain electromagnetic force value.
The technical solution of the utility model is: magnetometer is made up of magnetic force probe, spring and indicator; Magnetic force probe, spring are connected successively with indicator; Can form unidirectional spring magnetometer by one group of magnetic force probe, spring and indicator, also can form double-acting spring magnetic force by one or more magnetic force probes, 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.
In the utility model when work,, magnetic force probe is connected with spring, when magnetic force probe is in magnetic environment, is subject to the acting force in magnetic field and spring is produced compresses or stretching and drawing; The deformation that spring produces is directly delivered on indicator, and by the size of indicator for displaying deformation, shows the size of magnetic force.Compared with the measurement mechanisms such as the gaussmeter of prior art, can be according to measured spring deformation, directly judge the size of electromagnetic force, the power in magnetic field.
