Fastar®
Fast Response, Linear Displacement Transducer
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.
Features
- Body length only 1.3” longer than stroke
- Fast 35 µS response
- ±0.15% linearity, (±0.10% optional)
- Non-contact technology
