TECHNOLOGY

Electronic stud finders work by sending low-energy electronic pulses into the wall. As these pulses pass through the wall, some of the energy is absorbed by the material. Areas with denser material, such as where a stud is located, absorb slightly more energy than areas with less density. This difference in absorption allows the stud finder to detect the presence of studs.

However, a single reading is not sufficient to determine the location of studs. A high reading could mean that the sheetrock is thicker than normal, or it could mean that a stud is present. The stud finder can only figure out if a stud is present after the stud finder has been moved back and forth across the wall. As it scans, the stud finder builds a reference of what “high” and “low” readings look like for that particular section of wall. Then it can display the locations of studs. This is the basic explanation for how other electronic stud finders work. Although other stud finders are functional, they often lack accuracy.

Franklin Sensors takes a more advanced approach to finding studs. Franklin Sensors’ stud finders use multiple sensors to sense the wall in multiple locations simultaneously. Then a microcontroller in the stud finder compares the readings from several sensors, and uses advanced algorithms to determine the location of the stud.* The result is greatly enhanced accuracy, and no need to slide across a wall.

This patented technology is unique to Franklin Sensors, and is the reason that Franklin Sensors’ stud finders have become the preferred choice of professionals and homeowners alike.
