Introduction of the Differences, Advantages and Disadvantages of Fluxmeter and Gauss Meter
As for fluxmeter and Gaussian meter, many people don't quite distinguish between these two kinds of magnetic measuring instruments. They are commonly used measuring instruments by magnet manufacturers. What's the difference between them? What are their advantages and disadvantages? Today Xiaobian will come to share with you all.
First of all, the Gaussian meter, also known as Tesla meter, uses Hall element to detect the magnetic induction intensity of a point and a surface on a magnetic material or object. The Gaussian meter reads in Gaussian or millimeter units.
Fluxmeter is a unit of overall performance of magnetic material or object detected by coil using the principle of electronic integration. It is commonly used in magnetoelectric, electronic and digital integrated fluxmeter. General units: mWb, Wb and other units to express.
Advantages and disadvantages of fluxmeter and Gaussian meter
The advantages of Gauss meter are convenient, fast, intuitive and easy to carry.
The disadvantage of Gaussian meter: point test, inaccurate measurement, different person measurement, different manufacturer Gaussian meter measurement value is different, the same Gaussian meter probe different measurement value is different, test data has great divergence, the reason is that the Gaussian meter probe chip, probe packaging thickness, chip location, test Gaussian value is difficult to test at the same point, chip size is not the same. Similarly, there are magnetic inhomogeneity on the surface of the magnet. The Gaussian gauge is calibrated in the uniform magnetic field, so it is difficult to unify and compare the measured values of the Gaussian gauge.
Fluxmeter has the advantages of convenient operation and is an ideal instrument for measuring magnetic field and flux. The measurement is the overall average value of the magnet, which can reflect the overall performance of the magnet. The value of the magnetic flux can be completely compared and transmitted. The magnetic flux can reflect the overall performance of the magnet. For example, the surface magnetic height (a point high, can not represent all), the magnetic flux is not necessarily large; conversely, the high magnetic flux performance must be good (the synthesis of all magnetic lines in the magnet).
Disadvantage of fluxmeter: For each magnet sample with different specifications, it is necessary to make different size coils. Strictly speaking, for very thin samples, the preparation of detection coils is difficult and inefficient.
Magnetometer flux = field strength x area (under the condition of uniform magnetic field)
The magnetic field strength of Gauss gauge is the field strength of "a certain point"
