In recent times, a major problem our customers have encountered is the need for a short to medium range position sensor that is rugged and does not wear out, but at the same time, is not unduly expensive. The low cost issue drives these customers to resistance potentiometers, but because they are not very rugged and utilize an internal sliding contact, they wear out pretty quickly. In fact, in motor sports applications, it is fairly common to observe pots being discarded after just one race.
Alliance Sensors Group, a division of H.G. Schaevitz, LLC, has developed a linear position sensing technology called LVIT that offers an excellent price-to-performance ratio compared to other linear position sensing technologies such as LVDTs, linear potentiometers, and magnetostrictive devices. Furthermore, LVITs can offer the best stroke-to-length ratio of any contactless linear position sensor, because their overall length only increases by a relatively small percentage beyond their stroke.

With an aging infrastructure and major bridges that are more than 50 years old, the demand put on civil engineers to inspect our transportation system is ever increasing. Federal law requires every bridge over a 20 ft span to be inspected every other year.
