Gaging LVDTs

LVDT stands for Linear Variable Differential Transformer.  An LVDT is also referred to as a linear displacement transducer, or linear position transducer.  This sensor device measures linear displacement (or linear position) very accurately.  LVDTs can come in two physical configurations: free-unguided core or spring-loaded (gaging), as described below.

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.
