Education is too Expensive!

May 20, 2014

It has been said that if you think education is expensive,  try ignorance. The high cost of ignorance can affect all aspects of life. In industry,  this includes maintenance, machine reliability, safety and lost production. Unexploited opportunity is lost opportunity—a costly consequence of ignorance. The financial impact suffered from unplanned/unscheduled maintenance can be huge. You […]

Calibration – Can You Stand by your Measurements?

May 15, 2014

On a recent visit to a plant,  I came across this dial indicator with a calibration sticker. How often are your dial indicators calibrated? You depend on them for precise 1 thousandths accurate measurements, or tighter for high accuracy dial indicators. Routine calibration inspection should be performed on any precision measurement instrument. This includes your laser […]

Data Collection Time Improvement through the use of a Triaxial Sensor

May 13, 2014

As a vibration monitoring program becomes more mature,  the number of monitoring points on a machine and throughout a facility can increase to a very high number. These additional monitoring points are required to identify potential failures and maintain a world class reliability program. Unfortunately,  these additional measurement points usually result in an increase in […]
