LVDT Schaevitz® Transducers - XS-D Series
The XS-D Series is particularly well suited for measuring relatively large displacements, but where installation space is limited. The XS–D has a substantially greater displacement range than standard LVDTs but without the accompanying increase in body length and weight. Special winding techniques permit linear range measurements up to 80 percent of the XS–D’s housing length. In cramped servo mechanisms, linear potentiometers are traditionally used because of their shorter length. However, the XS–D series LVDT will readily fit in such restricted space applications. In addition, LVDTs are superior to linear potentiometers, particularly in high vibration environments. For example, dither, used to prevent static friction in servo systems, will rapidly consume a linear potentiometer. |

The LVDT, being a contactless device, experiences no wear whatsoever. Since a linear potentiometer’s output impedance varies with wiper position, its linearity is impaired when a significant load is applied.
Unlike the linear potentiometer, the LVDT has a constant low output impedance.
The 400 series stainless steel housing provides magnetic shielding.
