DX-2012MQ Magnetic Moment Testing Equipment: Installation and Testing
Introduction
The connection between magnetometers and Helmholtz coils to test the quality of rare earth materials has become the most popular mutual inspection method among enterprises. Using one-dimensional coils to test axially magnetized cylindrical, circular, and square rare earth permanent magnet samples, and configuring software DX-2012MQ can not only accurately test the total magnetic moment M (more accurately, Mz) of the material, but also for standard shaped NdFeB rare earth permanent magnets, such as square, cylindrical, and circular rings, the BH demagnetization curve under room temperature conditions is close to a straight line, which can accurately calculate the three important parameters representing magnetic performance Br, Hcb, and BHmax, meeting the rapid judgment of material magnetic energy quality.
Features
Designed with a medical-grade 3.5-inch TFT full-color display for more precise 6-digit numerical readouts.
Utilizes an intelligent drift adjustment dynamic algorithm, with the entire drift adjustment process requiring no manual intervention.
One-button measurement of magnetic moment (M), with automatic calculation of values such as Br, Hcb, and BHmax.
Features upper and lower limit sorting functions, displaying OK/NG sorting results.
Equipped with an automated communication interface for fast, automated magnetic flux testing and sorting.
Includes a standard USB interface, with accompanying measuring software for forming an automated measurement system to enable large-scale data storage.
