Problem: How do I ensure vibration data is collected in the same place every time? Solution: For a successful vibration analysis program, you must collect data consistently. To ensure consistency, always place the transducer in the same position every time you capture data at a particular location. Marking the position with either mounting pads or a permanent marker is recommended. If using a permanent marker, be sure to re-mark the location as needed as the mark likely will fade over time.

Problem: How do I collect a vibration reading on a vertical pump? Solution: Both horizontal and vertical measurements are parallel to the floor on a vertically mounted pump. We suggest that you collect the horizontal reading perpendicular to the piping and the vertical reading parallel to the piping on a vertical pump. In shipboard applications, horizontal will be in the athwartship (port/starboard or across the ship) direction while vertical will be in the fore/aft direction. Mr. O’s thanks for these tips go to the experts at Rockwell Automation.
