LINKJOIN T3-0303H ultra-thin hall sensor for magentic measuring trade assurance supplier
1. Probe Size:
2. The Selection of Hall Probe
Normally, in order to meet the different test requires, manufacturer supplies probes with different specifications. When purchasing Gauss meter, please take the following items into consideration.
1) Measuring ranges and resolution. It depends on the probe and instrument.
2) In Air-gap magnetic field measurement, dimension of probe is very important. The hall probe size should be smaller than the gap.
3) The direction of probe. It includes transverse and axial probe.
Transverse probe is suitable for measuring the Electro-magnet magnetic field, magnet's surface magnetic field. Axial probe is used for measuring the magnetic field of solenoid.
4) Line length of probe. Normally it is fixed. But it can also be changed according to the customer's requires.
5) Auxiliary tools. In some particular test environments, to ensure accuracy of test and repeatability comparability, tester should equip the special auxiliary tools.
3. Measuring Methods and Notes
The magnetic field direction should perpendicularly pass through the probe.
Measure the space and gap's magnetic field.
To measure the surface flux density of magnet, put the probe's concave side on the surface of the measured magnet or magnetic field measured points.
Following are the operate methods in detail:
CAUTION: The incorrect operation as follow.
