MDT Releases High-Resolution Three-Axis Digital Magnetometers
New Magnetometers with Open USB Communication Protocol Facilitate Rapid Prototyping and Customization for Magnetic Sensor Research and Development
MultiDimension Technology (MDT) will release the two new models of Three-Axis digital magnetometers for high-resolution 3D magnetic field measurement. They include USB27053 for 5 milliTesla low-field measurement and USB25103 for 2 Tesla high-field measurement, with a USB interface connecting PCs or Android devices. They are ideally suited for scientific research, industrial instrumentation or educational programs in a variety of applications, including 2D/3D magnetic field mapping, material property research, non-destructive testing, object detection and tracking, algorithms for magnetic sensing and sensor fusion.

"MDT's new USB magnetometers are designed with high-performance three-axis magnetic sensors, low-noise signal conditioning circuitry, high-resolution digitization with calibration by a microcontroller, and a USB interface communicating with PCs or Android devices. A user-friendly graphical user interface provides visualization of the 3D magnetic field in real-time, and configuration options for calibration, filtering, sampling rate, etc. MDT can customize the magnetometer to interface with any TMR sensors, Hall Effect or AMR/GMR sensors, allowing users to evaluate sensor performance and choose the best-suitable product for their applications. MDT also provides an open communication protocol that can be interfaced with any development platforms or programming languages such as LabView, Arduino, Matlab, C# or Python, facilitating rapid prototyping for new applications with ease. MDT's magnetometers are accessible to a wide-ranging user base from sensor technology researchers, application developers, test engineers, lab technicians, hobbyists to educators and students as a general-purpose magnetic sensing instrument and also a customizable sensor research platform." said Dr. James G. Deak, co-founder and CTO of MultiDimension Technology.
