The 3DM-CV5 family of industrial-grade, board-level inertial sensors provides a wide range of triaxial inertial measurements, computed attitude, and navigation solutions.
In all models, the Inertial Measurement Unit (IMU) includes direct measurement of acceleration, angular rate, delta theta, and delta velocity. Compensation options include automatic compensation for magnetic anomalies, gyro and accelerometer noise, and noise effects. In models that include computed outputs, sensor measurements are processed through and auto-adaptive estimation filter algorithm to produce high accuracy computed outputs under dynamic conditions. The computed outputs vary between models and can include roll, pitch, and yaw.
All sensors are fully temperature-compensated and calibrated over the operating temperature range. The use of Micro-ElectroMechanical Systems (MEMS) technology allows for highly accurate, small, light-weight devices.
SensorConnect software is a user friendly program for device configuration. MIP Monitor (MicroStrain Inertial Protocol) can also be used. Both packages provide for device configuration, live data monitoring, and recording.
Alternatively, the MIP Data Communications Protocol is available for development of custom interfaces and easy OEM integration.
The sensor operates independent of computer platform, operating system, or coding language.
