Crackdown on Piping Issues: A Geometric Survey of Pump Support Structure
The piping of this very large pump was about 10 feet in diameter, and structural cracks were forming. We measured the flatness of each individual bearing foot, and then measured that flatness against a best-fit plane of all four feet to check for soft foot. We also measured…

Motion Amplification in Action: A Closer Look
Jeff Hay, the CEO of RDI Technologies, discusses Motion Amplification; a camera based technology invented by RDI. Jeff believes that the camera is the sensor of the future because visualization is faster, safer, and makes the complex more simple. Since starting RDI, he has created and patented multiple methods for using camera technology to visualize and measure motion.

Cost Avoidance Within the Infrared World
Who does cost avoidance? What is it? Where would you apply it? Why would you worry about it? These are the questions that one should ask themselves. Most of the time is spent doing the physical work and analyzing that data to determine the condition or health of the equipment rather than thinking what our group did to save the company money. This article explains the methodology we used and why you should care about cost avoidance.
