Description

Quantifiable magnetic detection device

Technical Field

The utility model relates to a detection device specifically is a quantifiable magnetism detection device.

Background

The common magnetic detection device in the market at present generally comprises a magnetism measuring instrument and a permanent magnet. When the permanent magnet is used for detecting magnetism, the permanent magnet is adsorbed on a detected material, the magnitude of the adsorption force reflects the magnitude of the magnetism of the detected material, but the adsorption force is generally judged by human feeling. The magnetic measuring instrument is expensive, the use cost is high, the measuring operation is relatively complex, and a certain professional knowledge is required for a detector.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an easy and simple to handle, with low costs quantifiable magnetism detection device to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a quantifiable magnetic sensing device includes a target and a permanent magnet suspended directly above the target.

Further, the target is placed on a platform.

Furthermore, a stand column is further fixed on the platform, a cross rod is connected to the upper end of the stand column, and a connecting wire is connected to the other end of the cross rod.

Further, the permanent magnet is connected to the bottom end of the connecting wire.

Further, the permanent magnet is placed right above the circle center of the target through a connecting line.

Further, the target is concentric equidistant circle target.

Further, scales indicating the magnitude of magnetic strength are engraved on each concentric equidistant circle of the target.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses hoist the connecting wire for the permanent magnet, let its nature sag, place the mark target of a concentric equidistance circle under the end, directly over the permanent magnet is in the centre of a circle, can quantify the magnetic strength of being surveyed the material through the scale of above-mentioned concentric equidistance circle to there can be clear and definite judgement to being surveyed the size of material magnetism. In addition, the utility model has the advantages of simple structure, easy operation and low cost.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1, a quantifiable magnetic sensing apparatus includes a target 1 and a permanent magnet 2 suspended directly above the target 1, the target 1 being placed on a platform 3. Still be fixed with stand 6 on the platform 3, the upper end of stand 6 is connected with horizontal pole 4, the other end of horizontal pole 4 is connected with connecting wire 5, permanent magnet 2 is connected in the bottom of connecting wire 5.

The permanent magnet 2 is placed right above the circle center of the target 1 through a connecting wire 5. The target 1 is a target of concentric equidistant circles. Each concentric equidistant circle of the target 1 is marked with a scale indicating the magnitude of magnetic strength.

When the quantifiable magnetic detection device is used for measuring, the material to be measured slowly approaches the center of the circle of the target 1 from the outermost side of the target, whether the permanent magnet 2 deviates or not is observed, and when the deviation occurs, the scale of the target 2 where the material to be measured is located is regarded as the magnetic strength of the material to be measured.
