Hi Carolyn

Upfront let me say I know very little of LVDTs and have never used them, but they are a very elegant way of sensing linear displacement.

When you say they are inherently frictionless....although simple, they have moving parts so there must be some friction?  And in wet/icy conditions they could get frozen?

Were I to encounter the problems of crosstalk I would try something like using different excitation frequencies for each LVDT, and have a narrowband filter in each signal conditioner.   Are solutions like this used?   But Alliance's solution is also clever.  And I suspect thay know more than me about these things :-)

@Carolyn: Thanks for information. However, few grpahical presentation would have made it more facile to comprehend. Can digital signal processing can also be applied to dispense with this problem?
