As the data source of fault information monitoring and diagnosis, sensor's measurement of engineering equipment working parameters determines the accuracy of subsequent fault diagnosis, and is the key device of mechanical fault information monitoring. Due to the cost, volume and other reasons, the current piezoelectric acceleration sensors can not meet the actual needs of the industry. It has become a trend to use low-cost acceleration sensors for vibration analysis to achieve multiple fault detection of motor bearings.

The 52M30 acceleration sensor uses advanced piezoresistive MEMS sensing elements to provide superior dynamic range and stability. This acceleration sensor has a full-bridge output, operating temperature range from -40 to +90 ° C and measuring range from ±50 g to ±6000g. Gaseous micro-damping also provides excellent shock resistance and smooth amplitude response up to 7kHz.
