     We are also using LVDT's for a project. I feel I should mention they
are very accurate. We are using them to measure something to within 1/1000
of an inch. Anyway, here's where we got them:

     Schaevitz Engineering
     U.S. Route 130 & Union Avenue
     Pennsauken, NJ  08110

     Tex  (609) 662-8000

     Relevant technical bulletins: #7003B, #7007, #1002E

I don't know how much the LVDT's cost, but the driver circuit, which is
available from the same company, costs about $125. If you know the theory,
you could probably build one yourself. They explain how an LVDT works in
one of those technical manuals.

Hope that helps.
