Description

Technical Field

[0001] The utility model relates to the technical field of Gaussmeter probes, in particular to a portable Gaussmeter probe. Background Art

[0002] Millitesla meter (also called Gauss meter) is composed of Hall probe and measuring instrument. Hall probe generates Hall voltage due to Hall effect in magnetic field. Hall sensor is used as magnetic induction element. After measuring Hall voltage, the magnitude of magnetic induction intensity can be determined according to Hall voltage formula and known Hall coefficient. Gauss meter reading is in Gauss or kilogauss.

[0003] Patent (CN215678723U) discloses a probe for a gaussmeter, including a mainframe, a joint is movably connected to the top of the mainframe, a conversion block is fixedly installed on one side of the joint, a wire is fixedly installed on the side of the conversion block away from the joint, a first conductive sheet is arranged at one end of the wire away from the conversion block, one side of the first conductive sheet is fixedly connected to the connection block, and a limiting groove is provided inside the connection block. The utility model overcomes the shortcomings of the prior art. When the gaussmeter probe needs to be replaced, it is only necessary to press the moving block, and the moving block squeezes the limiting block to separate it from the limiting groove. After that, the new gaussmeter probe can be plugged into the connection block. At this time, the limiting block is squeezed by the connection block and thus squeezes the second spring inward. When it moves to the limiting groove, under the action of the second spring, the limiting block and the limiting groove are fixed to each other, thereby solving the problem that some existing instruments are time-consuming, labor-intensive and inconvenient to replace the gaussmeter probe.

[0004] The Gaussmeter probe in the above patent document is a soft thin strip probe. According to the working principle of the Hall sensor, the probe needs to be in parallel contact with the material to measure the magnetic field strength. The operation process needs to be cautious and meticulous and takes a long time. Once a large force is applied during the use of the probe, the probe will bend and crack, and then break. Moreover, the contact end of the probe is only 3-4mm wide, which is not easy to be in parallel contact with the material. The above problems result in the operator needing a long training time to master the operating skills, the measurement cycle is long, which is not conducive to rapid inspection, the probe is easily damaged, and the economic efficiency is very poor.
