FASTAR is a fast response, shock resistant,non-contact displacement transducer designed to measure linear displacement(position).A precision variable inductor with a stroke to body length ratio of almost 1:1, FASTAR has a body length approximately half as long as typical LVDTs. Used with a Sentech patented signal processor, it allows high speed displacement measuring with less error than other non-contact devices, with excellent immunity to EMI. FASTAR consists of a movable core inside a coil-wound tube. As the core moves in or out, coil inductance changes. The processor generates a DC voltage proportional to the change in inductance.
