MA-1040 Magnetic Analyzer

Detect and Measures Low Levels of Metallic Iron Compounds

MA-series Magnetic Analyzers feature sensitivity (down to ~0.00001% magnetic content), The MA-1040 is used to detect very low levels of magnetic iron in food, precious gems, pharmaceuticals, and many other materials. As evidence of its acceptance in industry, the MA-1040 has been referenced in American National Standards Institute (ANSI) and Abrasive Grain Association bulletins.

Particulate Systems’ MA-1040 Magnetic Analyzer incorporates modern electronics and features 0.1 parts-per-million (ppm) resolution, a wide dynamic range, and low power consumption.

Technique Overview:

The MA-1040 Magnetic Analyzer utilizes two matched air core coils, one as a reference, and the other receives the sample material to be analyzed. The coils are energized with an AC source of 683 Hz to reject stray 50 or 60 Hz line frequencies, a potential interference source always present in an industrial environment.

Any imbalance in resonance between the two coils resulting from the presence of magnetic material in the sample will produce a signal of strength proportional to the amount of such material. After synchronous detection, the signal is displayed digitally as percent magnetic content.

Operation is simple and straight-forward. A sample, the weight of which has been entered, is lowered into the center of the sample coil. A digital readout immediately displays the results.
