LORD Microstrain® 3DM®: 3-axis orientation sensor; capable of measuring: +/-180˚ of yaw heading, +/-180˚ of pitch, and +/-70˚ of roll
3DM® -- Discontinued -- Limited Availability
The 3DM® Orientation Sensor is designed to provide 3-axis static and quasi-dynamic orientation measurements. It incorporates 3 accelerometers and 3 magnetometers together with an on-board microprocessor, embedded software algorithm, non-volatile memory for configuration, and serial communication interface. Its form-factor, rated temperature range and power supply requirements are optimized for a broad array of applications. The 3DM® outputs acceleration vectors, magnetic field vectors, Euler angles (pitch, roll, yaw) and orientation matrix.
The 3DM® Orientation Sensor is initially sold as a starter kit with orientation module, RS-232 communication and power cable, universal wall transformer power supply, software CD, user manual and quick start guide.
The 3DM® Orientation Sensor is factory calibrated and ready for use with power-up. The 3DM® ships with easy-to-use Microsoft Windows software which allows the user to initialize, configure and operate the instrument, view real-time measurements graphically, and write data to file for post-processing. For those users, integrators or OEMs who develop their own applications, the 3DM® is shipped with a complete Data Communications Protocol guide that provides the developer with a complete instrument command set. Applications of your own design can readily be developed in any coding language and on any computing platform including microprocessors.
When outputting the orientation matrix, the 3DM® provides measurement of 360° about all 3 axes. When outputting Euler angles, 3DM® provides measurement of +/-180° yaw (heading), +/-180° roll, and +/-70° pitch. The 3DM® can operate in either polled mode (it outputs an orientation data packet on each host request) or continuous mode (it outputs orientation data packet after data packet to the host without request).
The 3DM® requires +5.2 to +12.0 volts DC to operate and can be powered by wall transformer, batteries, or any other capable power source. The enclosure provides a 2 hole mounting boss. Custom communication and power cables can be user fabricated or purchased from the factory.
