MTx

The MTx is a small and accurate 3DOF Orientation Tracker. It provides drift-free 3D orientation as well as kinematic data: 3D acceleration, 3D rate of turn and 3D earth-magnetic field.

The MTx is an excellent measurement unit for orientation measurement of human body segments. The standard version MTx has a full scale acceleration of 5g, full scales of 18g are available as well.

The MTx uses 3 rate gyroscopes to track rapidly changing orientations in 3D and it measures the directions of gravity and magnetic north to provide a stable reference. The systems real-time algorithm fuses all sensor information to calculate accurate 3D orientation, with a highly dynamic response, which remains stable over time.

MT Development Kit

First-time users should acquire the MTx Development Kit. This kit includes an MTx measurement unit, a calibration certificate, a user manual, a RS232 (USB Cable) and our user friendly MT Software Development Kit (SDK).  The Development Kit allows users to fully explore the possibilities of the MTx, and the integration possibilities of the MT with your own system. With the Development Kit you have will have your measurement unit up and running in just a few minutes to start your first R&D.

Pre-set user scenarios are available optimizing the Extended Kalman Filter routine for different applications. Based on the chosen scenario the XKF will apply appropriate filter settings recommended for the application.

With the MTx Development Kit, the MTx can be easily integrated in any system or (OEM) application.

The MTx is available as a stand-alone unit or as an Xbus version. On the Xbus, Xsens’ digital data bus, multiple MTx’s can easily be used simultaneously, enabling ambulatory and cost-effective measurement of human motion.
