Click For Summary
To model a Linear Variable Differential Transformer (LVDT) using differential equations and transfer functions, one should begin by establishing the physical principles governing the LVDT's operation. The discussion highlights the challenge of formulating a differential equation for the system, which is crucial for deriving the transfer function via the Laplace transform. A helpful resource is provided, linking to a theory overview on LVDTs that may assist in understanding the underlying mechanics. Engaging with foundational concepts in sensor theory can facilitate the modeling process. Seeking guidance on specific aspects of the differential equation formulation is encouraged for clearer insights.

hello all!

Does anybody have any idea how i get get a transfer function for a Linear Variable Differential Transfromer (LVDT).

I thought about generating a differential equation to model the LVDT and then taking the laplace transform of this. My problem is: I am really stuggling to model the system with a diff eq - does anynody have an idea where i should start.
Please help.

Thank you
John

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
