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?

Systems Energy and Emissions Analysis with Electrical Signature Analysis
There are several ways to view the impact of maintenance practices using ESA and electrical measurements, the first is the use of simple overall kilowatt readings from a power analyzer or relay monitoring system; the second is the before and after readings from an ESA device that identifies kilowatt data by defect.

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.

Utilizing Phase to Confirm Machine Faults
It’s on all of the vibration fault charts, it’s taught in vibration classes, and it’s used for balancing – but how often is phase actually used by vibration analysts to confirm faults?
