Model 333D01 is a fully integrated and ruggedized packaging of a high-resolution, broad-frequency piezoelectric accelerometer with integrated internal digital data acquisition that uses the USB port to connect to tablets, smartphones and computers. The roto_digiducer.framework is a tool to communicate with the sensor to collect and process data. Test was performed using a variable frequency shaker to generate a constant amplitude and the response was processed using the roto_digiducer.framework.


Plot 1 represents the frequency response plot showing the deviation of the amplitude of the sensor in % at room temperature measured using the roto_digiducer.framework which reads the sensor calibration data directly from the sensor and processes the overall acceleration value then compared to the calibrated shaker amplitude response. Plot 2 represents the manufacturer's typical response curve. Plot 3 represents the response using roto_digiducer.framework freq_resp_correction function
