Using LVDT technology, Trans-Tek manufacturers three different lines of Gaging Transducers capable of measuring up to 20 inches. Gaging transducers are often selected over free-unguided LVDTs when a hard connection cannot be made to the moving object. All units consist of a spring-loaded shaft guided through a phosphorous bronze, leaded bearing. A hardened steel contact tip touches the object to be measured.
