Electromagnetic field fluxmeter DX-330A

digital

Overview

The DX-330A is a precision three-dimensional digital flux meter designed to measure magnetic flux and magnetic fields. It is intended for research and analysis of permanent magnets and soft magnetic materials, and for mass measurement workflows when paired with PC software.

Key features

• High acquisition and display resolution: six-digit display on a 3.5-inch true-color TFT for accurate readings.
• Intelligent automatic drift adjustment with no manual intervention required.
• "Zero first then test" method to eliminate the magnetic flux zero point; direct display of magnetic flux values for simplified operation.
• Built-in upper and lower limit sorting with OK/NG results for quality screening.
• Automated communication interfaces to support rapid automated magnetic flux testing and sorting.
• Automatic compatibility with multiple measuring coils and fixtures without parameter reconfiguration.
• Standard USB Type-B interface and optional measurement software for automated systems and mass data storage.
• Three simultaneous measurement channels.

Testing methods

• Cylinder magnetic flux test: place the sample in the sample stage so that the magnetic field lines pass vertically through the coil.
• Magnetic tile test: place the sample in the sample stage so that the magnetic field lines pass vertically through the coil.
• Coil (longitudinal probe) measurement: place the longitudinal probe in the central area of the solenoid for measurement.
