Hello there, I am currently using LDVT probes to measure linear displacement (goes without saying, but I said it anyway). The problem with this is that the wire for the probe is very cumbersome and requires extra machining to external parts in order to accommodate the wire without disruption. Therein, some of the machining may be causing disruption itself! I typically don't get into the details of the equipment used, though I think it's finally time to start looking at alternatives. Problem is, I don't really know where to begin. Does anyone know of any wireless alternatives to LVDT probes? Essentially anything wireless that can detect linear motion; the smaller and less cumbersome the better, regardless of price. Preferably with high resolution (able to detect movement on the order of microns). Thank you everyone.
