MEMS Accelerometers and Yearly Calibration
A handheld portable vibration data collector typically uses a piezoelectric sensor. Normally this would require a calibration every year or two, as a piezo crystal output can drift over time. MEMS (Micro-electromechanical systems) accelerometers do not require recalibration every year which make it ideal for use in a wireless vibration sensor. Why is this?

Best Practices and Troubleshooting for Permanently Installing Accelerometers
Today we sit down with Peter Eitnier, the Senior Applications Engineer for Wilcoxon Sensing Technologies. He will be going into detail on best practices and troubleshooting for permanently installing accelerometers. Vibration sensors and acelerometers should be mounted, in general, as close as possible to the bearings. The shaft turning speed is the driving force for both the machine itself, and the vibration signal.

MEMS Accelerometers – Technology Review and Implications for CBM
In this session we will compare and contrast MEMS accelerometer technology with legacy PZT, discussing the implications for IIoT and CBM applications in general. We will demonstrate how MEMS performance improvements made over the last 5 years not only supports overalls trending but also enables bearing fault detection and diagnostics. With a better understanding of the underlying sensor technology strengths and limitations, we will also show how MEMS accelerometer performance positioning data suggests using caution when selecting wireless IIoT solutions for your assets.

Making It In A High Frequency World Striving for High-Frequency Industrial Accelerometers
As predictive maintenance teams in industrial facilities strive for a more complete picture of their equipment’s health, high frequency vibration measurements have become a crucial addition to identify faults such as motor and pump bearing defects and gear tooth inconsistencies in high-speed gearboxes. As a result, there is an upsurge in demand for vibration sensors with a high frequency response.

Sensor Aging and MTBF
Most general-purpose industrial accelerometers tend to come with lifetime warranties so that if anything should happen within the boundaries of normal usage, you can receive a replacement quickly enough and get your vibration monitoring program back on track

Why MEMS Accelerometers Are Becoming the Designer’s Best Choice for CbM Applications
A small number of semiconductor manufacturers have overcome the noise, bandwidth and g-Range shortcomings commonly associated with MEMS sensors used in Condition-based Monitoring (CbM) by producing several medium and high-performance MEMS vibration sensors with the latter being comparable to piezo accelerometers.
