Microminiature Solid State 3-axis Pitch, Roll, and Yaw Sensor
The 3DM-DH® OEM 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 and is specifically targeted at OEM and downhole users. The 3DM-DH® outputs acceleration vectors, magnetic field vectors, Euler angles (pitch, roll, yaw) and orientation matrix and has optional analog output.
Easiest to Use
- out-of-the-box pitch, roll, and yaw
Best in Class
- high-speed sample rate & flexible data outputs
- extended use, low-power data logging
- reduced cost and rapid time to market for customer’s applications
- aggressive volume discount schedule

The term ‘static’ accuracy refers to measurements made when the inertial unit is not moving and the on-board orientation algorithm has recovered from any sensor over-ranging.
The term ‘dynamic’ accuracy refers to measurements made while the inertial unit is moving and not exceeding the measurement range of the individual on-board sensors (accelerometers, gyroscopes, magnetometers).
The 3DM, 3DM-DH and FAS-A are designed to measure static rotations.
The 3DM-GX3 family is designed to measure both static and dynamic rotations.Direct link: view
From time to time the inertial sensor may need recalibration.
Example: If the inertial sensor contains magnetometers, coming in contact with magnetic influences (magnets, motors, etc.) may cause residual magnetism to be picked up by the on-board components which alter the calibration. In these cases, the inertial sensor should be returned to the factory for recalibration.
Example: The inertial sensor receives a severe shock, slightly altering the position of the circuit boards in relation to the enclosure, again altering the calibration. In these cases, the unit should be returned to the factory for recalibration.Direct link: view
Yes. The unit is factory calibrated and ready for use with power-up.Direct link: view
The sensor can output:
- magnetic fields
- Euler angles (pitch, roll, yaw)
- orientation matrix
Yes. A Windows XP/Vista/7 compatible software is shipped the product. The software allows the user to configure, operate, display and save data from the sensor.

The 3DM-DH can measure static and quasi-dynamic rotations with an accuracy of:
- pitch +/-0.7 degrees (typical)
- roll +/-0.7 degrees (typical)
- yaw +/-1.5 degrees (typical)
Direct link: view
The 3DM-DH is a 3-axis orientation sensor capable of measuring:
- -180˚ to + 180˚ of yaw (heading)
- -180˚ to +180˚ of roll
- -90˚ to +90˚ of pitch (see note following)
Note: The 3DM-DH has a pitch range of +/-90˚. It will measure pitch accurately within this range. However, due to a mathematical singularity in the Euler theorem, as pitch exceeds either -70˚ or +70˚, the yaw and roll measurements of the 3DM-DH will become numerically unstable. So to put it another way, if you are just measuring pitch with the device, all measurement between -90˚ and +90˚ will be accurate. If you are measuring pitch and roll at the same time (for example), pitch measurements beyond -70˚ or + 70˚ will effect the accuracy of the roll.

#664: Is it possible to use the RS-232 interface of LORD MicroStrain® inertial sensors with a serial port emulator (i.e., with a USB to serial adapter)?
Yes. We have had good success with several types of off-the-shelf USB to serial port adaptors, such as those from IOGear and Keyspan, which may be purchased through any of the electronics products distributors.Direct link: view
