Knoxville-based company RDI makes waves in motion sensing

The Knoxville-based company sells a package of camera, computer and software to monitor vibration. Thanks to an algorithm developed by CEO Jeff Hay, movement of any pixel is magnified to show just where vibration is occurring. And the information is available immediately, instead of taking days to gather and analyze.
Industrial uses are RDI’s main focus, but the technology has applications in medicine and other fields.
Beginnings and growth
The company started in 2013, went to market in 2015, and sells to companies worldwide, said President Bob Wilson.
“We’re growing at about 300 percent a year, year over year,” he said.
Vibration sensors have been around for a long time, but standard ones are contact-based: they have to actually touch what’s being monitored. That can cause safety problems, and trouble monitoring very small or very large objects, Hay said. With each camera pixel acting as a sensor, though, an object can be studied from a distance.
“If you can see it, we can measure it,” Wilson said.
Contact sensors can take a day or more to collect vibration data from an object, Hay said; even then, the readings have to be pieced together into usable information.
“With us, it’s simultaneous,” he said.
The company’s Iris M system is a kit including a digital camera, four lenses, tablet computer, tripod and USB cable in a case, Johns said. Also included in the $30,000 bundle is the necessary software and certification training to use it, Wilson said. Components are made elsewhere, but everything is assembled in Knoxville, said Chief Operating Officer Jenna Johns.
