Digital inertial module (INS) for 3D vibrational analysis (3D accelerometer only)

Module specifications:

The digital inertial module is designed for linear acceleration or vibration measurements, which are typically caused by machine misalignment and unbalance. The sensor includes a sensing element and an IC interface able to take the information from the sensing element and to provide the measured acceleration signals to the external world through an I2C/SPI serial interface. The inertial module may be connected to the sensor network due to the implemented RS485 interface, which allows multipoint vibration measurements. The integrated three 12-bit ΣΔ ADC (analog-to-digital converter), one for each axis, and low noise capacitive amplifier conduct to the high sensitivity, low power consumption and high speed output data rate.
