DX-220A Digital Flux Meter

Built-in 24bit AD high-precision data acquisition system independently developed by Dexinmag, the acquisition resolution reaches one millionth, and the display resolution reaches one millionth. During the measurement process, the data will not be lost, and various magnetic fields or permanent magnets can be measured. Magnetic flux Ф and other data, and has functions such as automatic sorting of upper and lower limits. The instrument is equipped with an automatic control interface, which can realize automatic quality screening and control of the measurement parts.
The DX-220A digital fluxmeter adopts the "record zero first and then test method" to eliminate the zero point of the magnetic flux, reducing the cumbersome operation of repeated zero reset by the user. It can be widely used in the research and analysis of permanent magnets, soft magnetic materials, etc. In fact, it is necessary to configure windows host computer software to realize massive data storage.

Introduction to Testing Methods

 

Testing the magnetic flux of a cylinder: Place the sample in the sample stage to ensure that the magnetic field line passes vertically through the coil.

 

 

Test the magnetic flux of the magnetic tile: Place the sample in the sample stage to ensure that the magnetic field line passes vertically through the coil.

 

 

Schematic diagram of coil measurement sample magnetic flux: Place the longitudinal probe in the central area of the solenoid and perpendicular to the magnetic field line.
