This minimises industrial noise and allows for easy expansion of the sensor network.


High Precision and Low Noise Both sensors exhibit high sensitivity and low noise levels, enhancing the accuracy of vibration data. The AVS 1001HF’s sensitivity of up to 100mV/g with a noise density of 4µg/√Hz and the AVS 1003LF’s noise density of 80µg/√Hz ensure precise measurements even in challenging industrial environments.


MEMS Technology


The core of these sensors lies in MEMS technology, which combines miniature size with high performance. MEMS sensors offer robustness and durability, crucial for demanding industrial applications.


IMPORTANCE OF HIGH BANDWIDTH AND TRIAXIAL SENSING


High Bandwidth for Capturing Faults The ADXL1002 single-axis accelerometer, with its


11kHz, 3dB bandwidth, is crucial for capturing high frequency bearing and gearing faults that lower bandwidth sensors might miss. This high bandwidth capability enables detailed analysis of critical components, ensuring early detection and prevention of potential failures (see Figure 3).


Triaxial Sensing for Comprehensive Monitoring


Triaxial sensing solutions, such as those provided by the AVS 1003LF, are essential for predicting faults that might be overlooked by single-axis sensors. By capturing data across three axes, these sensors offer a more comprehensive view of the machinery’s condition, leading to better fault prediction and maintenance planning.

The AVS 1001HF and AVS 1003LF accelerometer sensors were integrated with AMC cloud-based condition monitoring systems. The raw signals from the sensors are sent to the edge processing unit. The unit calculates diagnostic features and sends the data to the cloud server. Customers can access information about machinery health quickly and conveniently. The following plots are available: map, custom mimic (with several components like bar graphs), alarms, trend, waveform, spectra, etc. Figure 4 presents a few plots from the system. The configurable bar graph plot is a quick assessment view for operators. If there is a limit
