MELDOR-MAG-26 Digital 3-Axis Fluxgate Magnetometer
Precision Without Compromise
The MELDOR-MAG-26 is a high-performance digital 3-axis fluxgate magnetometer developed for applications where measurement accuracy, thermal stability, and long-term reliability are critical.
Unlike conventional fluxgate magnetometers, the MELDOR-MAG-26 combines fully digital signal processing, ultra-precise orthogonality calibration, high-temperature operation up to +145°C, and a compact mechanical design in a single instrument.
The sensor is intended for demanding applications including directional drilling (MWD/LWD), scientific research, industrial automation, and navigation systems where vector magnetic field accuracy is essential.
Engineered Around Four Core Principles
Fully Digital Architecture
The MELDOR-MA-G26 was designed as a fully digital instrument rather than a traditional analog fluxgate magnetometer with a digital interface.
All signal processing, compensation algorithms, filtering, and calibration are performed digitally. This architecture minimizes analog errors, improves repeatability, enhances long-term stability, and provides consistent performance throughout the sensor’s lifetime.
The result is a magnetometer whose characteristics remain stable under changing environmental conditions without the limitations associated with complex analog circuitry.
Orthogonality Better Than 0.05°
Vector magnetic field measurements depend not only on sensor sensitivity but also on the precise geometric relationship between the three sensing axes.
Every MELDOR-MAG-26 undergoes individual factory calibration to achieve sensor orthogonality better than 0.05°.
This exceptional alignment minimizes vector calculation errors and allows highly accurate determination of magnetic field direction, making the sensor particularly suitable for precision navigation, scientific instruments, and directional drilling systems.
Designed for High-Temperature Operation
Many precision magnetometers experience significant performance degradation at elevated temperatures.
The MELDOR-MAG-26 has been specifically developed for reliable continuous operation at temperatures up to +145°C while maintaining stable measurement characteristics.
This makes the sensor ideally suited for harsh environments such as oil & gas exploration, geothermal applications, and industrial monitoring systems.
Compact Size, Professional Performance
Achieving high accuracy typically requires large sensor assemblies. The MELDOR-MAG-26 demonstrates that precision and compact dimensions can coexist.
Its compact cylindrical design enables easy integration into space-limited systems while delivering measurement performance expected from significantly larger instruments.
Why Accuracy Starts With Geometry
In many applications, improving sensitivity alone does not improve measurement accuracy.
For vector magnetometers, precise orthogonality of the three sensing axes is equally important. Even extremely sensitive sensors cannot achieve accurate vector measurements if the geometry between the axes is not precisely calibrated.
For this reason, orthogonality calibration is one of the key technologies incorporated into every MELDOR-MAG-26.
