List-Magnetik Magnetic field meters / Gaussmeters
Measure the maximum strength of a magnetic field
Low Magnetism - Magnetic Field Meters for Permeability and Remanence
Unit of magnetic field strength (H)
The unit of measurement for the strength of the magnetic field is “Ampere per meter” (A/m). Because of the low values, A/cm are used more, or kA/m, older also Oersted (Oe). Because the magnetic flux density B, measured in Gauss (Gs) or Tesla (T), can be converted using a constant factor, the magnetic field strength and flux density (and thus the units A/cm, kA/m, Oe, Gs, T) can be used alternately. |
Axial and tangential probes for measuring magnetic fields
Axial probes measure in the direction of the probe. Tangential probes measure at an angle of 90° to the probe. The difference lies in the assembly of the Hall sensor. Tangential probes are more suitable for measurements in cavities or narrow pipes. An advantage of the axial probe on measuring devices from List-Magnetik is the distance of 2mm between the Hall sensor and the probe cap. In ball bearing production, this distance has become the de facto standard for the probe. Ultimately, you can say that the tangential probe is the more universal tool. Because practically all measurements of the axial probe can also be carried out tangentially. |
Calibration standard / reference magnet - an important accessory for the magnetic field measuring device or gaussmeter
A calibration standard is a reference magnet, a permanent magnet that always shows the same value when the same probe is in the same position. This allows you to safely check that the probe is still working correctly. In the case of precision calibration standards, the axial or tangential probe is held in the opening in such a way that it cannot shake. The combination of device, probe and standard forms a unit that is calibrated and certified together. The use of a probe on a calibration standard that has been coordinated with another probe can result in the reference value deviating minimally. This is because probes cannot always be built exactly the same. However, this deviation is always constant. |
Measure the magnetic flux with a fluxmeter
The question here is: how strong is a magnet overall? Not only the field strength at the pole, but the entire magnet is measured with a flux meter. In combination with a Helmholtz coil, the magnetic flux of permanent magnets can be determined very precisely, since the entire volume of the magnet is viewed independently of the position. In the coil, the effect of the magnet on the coil winding is determined in the form of an electrical voltage and converted into flux. |
Transfer data from the magnetic field meter / gaussmeter to the PC or app
Do you need to document or archive your series of measurements? Would you like to recognize extreme values and carry out statistical evaluations? Then our MP-800 app for Android and PC applications are the right tool. The applications enable measurement series to be further processed or integrated in Office applications. Integration into CAQ systems is also possible. |
