Triboelectric effect on vibration accelerometers

August 26, 2014

There are two primary types of accelerometers: one is the ICP (integrated circuit piezoelectric) having voltage output, and the other is known as a CLD (current line drive) type, with a current output. The standard ICP accelerometer has a nominal output of 100 mv/g and the output of a standard CLD accelerometer is 9.81µA/g. Cable […]

Determining Proper Equipment Data Collection Intervals

July 31, 2014

Guest post by Brad Loucks, Mechanical Engineer at Pioneer Engineering In a condition monitoring vibration program, determining the appropriate intervals of data collection is just as important as the data that is being analyzed. Properly scheduled data collection intervals of equipment provides data analyst with a better picture of how equipment is performing over a […]

Location! Location! Location! Vibration sensor placement is crucial.

June 24, 2014

For the highest confidence level possible while doing predictive vibration analysis work, location and placement of your sensor are crucially important to you. However, sensor placement is sometimes a trade-off between time, safety, and precision. Most equipment is mounted with the shaft oriented horizontally to the ground and the analyst must decide whether to take […]

Two examples of how vibration monitoring saved time and money in heavy industrial settings

June 10, 2014

New portable and online-monitoring systems help extend the value of vibration monitoring into the heaviest of industrial operations. Here’s a look at how users avoided serious motor failure in mining and detected a critical bearing failure in paper-pulp production by using the right vibration products at the right moment. Case Study #1: A Phosphate mine […]

Finding the running speed of a machine

April 8, 2014

Proper vibration data collection and diagnostics requires knowing the accurate operating (turning speed) of monitored equipment.  The most common tools used for measuring equipment turning speed are a tach (tachometer) and strobe (strobe light). If a means to determine equipment speed is unavailable, then an advanced vibration analyzer like VibXpert may have additional capabilities to […]

Remote Vibration Data Collection in Rotating Equipment

November 26, 2013

Vibration data collection on plant equipment can be very problematic due to safety concerns, time constraints, access difficulties and other reasons. Solution: The use of a termination switchbox and vibration sensors can allow an analyst to safely collect vibration data away from conditions that could complicate or event prevent manual readings from being taken due […]
