High-temperature digital 3-axis fluxgate magnetometer MELDOR-MAG26
Introduction
Modern demands on measuring instruments across various fields of science and technology are continuously increasing, with growing expectations for accuracy, reliability, and versatility. As tasks become more complex and application areas expand, there is heightened interest in next-generation magnetometric devices. One such solution is the MELDOR-mag26 fluxgate magnetometer, which combines compact dimensions, resistance to external influences, and high sensitivity.
Next-Level Engineering Solutions
A miniature form factor, thoughtful design, and stable performance at high temperatures — the new fluxgate magnetometer was developed with real-world engineering challenges in mind. Its compact size allows for easy integration into complex measurement systems, while its measurement precision remains at the level of professional equipment. It is a tool you can rely on for critically important data.
Design and Functional Components
Structurally, the MELDOR-mag26 magnetometer is implemented as a standalone measurement module with a mechanically rigid housing that contains three mutually orthogonal fluxgate sensors for recording all three components of the magnetic induction vector. The electronic section includes power supply circuits, control units, analog and digital signal processing components, and a data transmission interface. This design provides compactness, ease of installation, and stable operation over an extended temperature range.
Unique Features
One of the key advantages of this magnetometer is its compact size while maintaining high measurement accuracy. The device has a diameter of only 26 mm and a length of 67 mm, making it one of the smallest magnetometers in its class. Thanks to its small dimensions, the device is ideal for placement in confined spaces, ensuring accurate measurements in challenging operating conditions. This design opens up wide possibilities for applications in systems where the size of measuring equipment is a critical factor.
Operating Principle
The fluxgate magnetometer operates on the principle of detecting periodic changes in magnetic flux through ferromagnetic cores made of soft magnetic material. When an alternating current is applied to the excitation coil, it generates an alternating magnetic field that induces cyclical changes in the magnetic permeability of the ferromagnetic cores. These changes result in modulation of the magnetic flux passing through the cores.
A sensing coil, positioned to efficiently detect magnetic field variations, captures the changes in magnetic flux and generates an electromotive force (EMF). The magnitude of this EMF is proportional to the intensity and direction of the external magnetic field being measured. The resulting electrical signal forms the basis for determining the components of the magnetic induction vector.
