max. depth 7,000m
The Mag3 is suitable to determine the orientation in the magnetic field, the position (inclination) as well as the depth. The integrated magnetometer measures three mutually perpendicular components of the magnetic field vector. In combination with integrated tilt sensors, the compass direction is correctly determined even if the probe is tilted.
The module used is a tilt-compensated compass with a 3-axis magnetometer, a 3-axis gyro-meter and a 3-axis accelerometer. A Kalman filter combines the gyro and accelero-meter to remove errors caused by tilt of the probe. The output of the magnetometer and the pitch and roll angles are used to calculate the compass direction.
