DC Fastar®

Fast Response, Linear Displacement Transducer

The DC FASTAR® is a fast response, shock resistant, non-contact displacement transducer designed to measure linear displacement (position).

The DC FASTAR® is position transducer consists of a cylindrical body and low mass, aluminum movable core and a compact signal processor connected to the transducer with a 10′ (3m) cable.

A precision variable inductor with a stroke to body length ratio of almost 1:1, DC FASTAR® has a body length approximately half as long as a typical LVDT having a comparable measurement range.

The DC FASTAR® patented signal processor allows high-speed displacement measuring with better precision than other non-contact devices. Developed for use in rugged factory environments, the compact NEMA 4 (IP 65) rated signal processor is placed at or near its transducer, allowing the use of low-cost power and signal lines to run long distances to readout or control devices. It is highly resistant to EMI or RFI interference.

Operating from a single-ended +10 to +36V, units are available with outputs of ±10V DC, 0 to 10V DC or 4-20mA suitable for feeding PLCs, readouts or other control devices.
