Introduction

AH106B is MEMS inertial measure unit composed of three axis MEMS gyroscope(measure the three directions absolute angular rate of carrier), three axis accelerometer(measure the three directions linear acceleration). It output analog signal, the signal goes through 24digit A/D enhancement, sampling and analog-digital conversion, enters CPU.The aquisition CPU transmits the original code to compensation calculation CUP through serial port. The gyroscope signal is pulse signal, it enter compensation calculation CUP without conversion. The compensation calculation CUP processes calculation first, and temperature compensation, scale factor compensation, gyroscope bias&Incremental calibration bias correction, installation bias compensation, non-linearity compensation, then the angular rate and acceleration data in motion coordinate of carrier are output at last. Digital version AH106B adopts serial port directly, RS232, RS485, RS422 are available. Analog version AH106B output 0-5v or 4-20mA after digit-analog conversion of calibrated data.

Working Principle

Shell Size Chart
Structural rigidity, aperture coupling reduce and electromagnetic shielding are achieved by whole cutting
process. The shell groove design makes it beauty, lighter and better heat dissipation(natural cooling, no
need of additional cooling equipment) without compromise of structural rigidity, outline drawing as below

Installation precautions
Make sure correct installation, wrong installation may cause error, pay attention to one surface, two lines:
1）The Sensor mounting surface and the measured surface must be fixed closely, smoothly, stable, if
mounting surface uneven likely to cause the sensor to measure the angle error.
2) The sensor axis and the measured axis must be parallel ,the two axes do not produce the angle as
much as possible.
