In-depth Tutorial on Linear Position Sensors (LVDTs) Featured
on Macro Sensors Website

Pennsauken, NJ, September 1, 2009…

Macro Sensors offers an in-depth tutorial on Linear Variable Differential Transformers or LVDT linear position sensors on its web site at http://www.macrosensors.com/lvdt_tutorial.html. The tutorial covers everything you want to know about LVDTs including construction, significant features, operation and industrial applications. It even answers questions on where to use an LVDT and what types of electronics work best for specific applications.

A tried and true technology, LVDTs can measure movements as small as a few millionths of an inch up to several inches as well as positions up to ±20 inches (±0.5 m). Commendable features such as friction-free operation, infinite resolution and unlimited mechanical life make LVDTs the preferred technology in a wide variety of applications such as industrial automation manufacturing, power generation, civil engineering as well as industrial and subsea environments.

Macro Sensors offers an extensive line of LVDTs including AC- and DC-operated versions, linear and rotary sensors, free core and spring-loaded technology, hermetically sealed and high temperature resistance units as well as custom products.
