A linear variable differential transformer (LVDT) is a type of electrical transformer/transducer used for measuring linear displacement (position). A counterpart to this device used for measuring rotary displacement is called a rotary variable differential transformer (RVDT). The RVDT is like an LVDT in that it measures a positional displacement, however, the displacement, which is still a linear proportional function, is based on rotary instead of linear positional movement.

High Accuracy AC Reference Source
515
-
Clarke-Hess Communications Research
The Model 515 High Accuracy AC Reference Generator fills a need for a relatively low cost and practical solution for supplying a reference excitation to typical LVDT and Synchro/Resolver transducers. The Model 515 has built-in load sensing which, in effect, yields "zero" output impedance and virtually eliminates the effects of fluctuating output loads. With up to 15 VA of output into loads with as much as 80 of phase shift, the Model 515 is ideally suited to driving inductive loads.
