3DM Orientierungsaufnehmer
MicroStrain's Prokuktpalette mit Inertial-, Orientierungs- und Neigungs-Sensoren umfasst einfache Neigungssensoren (Tiltmeter oder Inclinometer), Inertial Messsysteme (IMU) und Kurs- / Lage-Referenzsystem (Attitude/Heading Referenz Systeme (AHRS)).
Diese Sensoren liefern Neigungswinkel (1 oder 2 Achsen), lineare Beschleunigungen und Drehraten aber auch die Orientierung in Form von Pitch, Roll und Richtung (Yaw or Azimuth) sowie die Quaternionen- oder Orientierungs-Matrix.
Achtung: In den Datenblättern der 3DM-GX-Serie hat sich ein Druckfehler eingeschlichen.
Die Angabe der "Gyro Bias stability" soll lauten: Gyro Bias Instability: +/-0.01°/sec
3DM is a 3-axis orientation sensor capable of measuring: ± 180 degrees of yaw heading, ± 180 degrees of pitch, and ± 70 degrees of roll. Orthogonal arrays of magnetometers and accelerometers are used to compute the pitch, roll and yaw angles over a wide angular range.
The 3DM is sold as a starter kit for the first unit purchased, afterwhich, just the board can be purchased. The starter kit includes the standard board, enclosure (shown), software, requisite serial communications and power cable, and a manual.
The Windows® software provided communicates with 3DM over a serial port. The software gives the user complete control over how data is processed, presented, and logged. The output may be programmed to provide raw magnetic field and accelerometer outputs, or processed pitch, roll, and yaw outputs. User programmed digital filters are used to process sensor data either statically or dynamically, depending on the change in 3DM movement over time.
3DM runs off of a single supply positive voltage ranging from 5.3 to 12 volts DC. 3DM's can be used alone or combined in networked arrays.
