IMU-7LN/MF Inertial Sensor 6DOF

IMU Inertial Sensor

  • Rotation +/-75 to 900 Deg/Sec
  • Acceleration +/-2g, 5, 10, 25 or 50g
  • Bandwidth up to 700 Hz
  • Low Noise 0.018 Deg/sec/Hz

Product Description

The ASC IMU 7.X.Y incorporates either the LN-series (Low-Noise) accelerometers or the MF-series (Medium-Frequency) accelerometers, featuring an acceleration range from ±2g to ±50g. The IMU features MEMS vibrating ring gyros with a rate range from ±75°/s to ±900°/s. ASC IMU 7.X.Y can be powered by a DC power supply where the output voltage is independent of the supply. The miniature IMU is made of lightweight anodised aluminium housing and features the industry standard 12-pin comtronic connector and a detachable cable.

Product Features

ASC’s capacitive accelerometers are based on MEMS sensing technology and produce an analog voltage proportional to the input acceleration. The accelerometers can measure both static (gravity) and dynamic accelerations. ASC’s MEMS capacitive accelerometers can be used for very low to medium frequency vibration measurements. The sensors feature a MEMS sensor element where the seismic mass is connected between two conductive capacitor plates. When subjected to an input acceleration, the seismic mass oscillates between the two capacitor plates and there is a change in the capacitance. This change in capacitance is converted via an ASIC (Application Specific Integrated Circuit) into a low impedance analog voltage output signal.

ASC’s precision navigation and pointing gyroscopes are made of robust silicon MEMS vibrating ring elements. The gyro detects the magnitude and direction of angular velocity by using the coriolis force effect. As the gyro is rotated, coriolis forces acting on the silicon ring cause radial movement at the ring perimeter, the magnitude of which is proportional to the angular velocity of rotation. The gyro produces an analog voltage signal, which is linearly proportional to the angular rate. The balanced ring design results in excellent shock and vibration rejection.
