Overview
The GRANITE?VWIRE
305 is an eight-channel interface for dynamic measurements of standard
single-coil circuit vibrating-wire sensors. With the VWIRE 305 interface, you
can operate traditional “static” gages at “dynamic” rates to achieve faster and
better measurements without having to purchase or install new sensors.
The interface measures the resonant frequency of the wire
between excitations using the patented vibrating-wire spectral-analysis
technology (VSPECT®).
VSPECT® provides
very fine measurement resolution and limits the influence of external noise by
discriminating between signal and noise based on frequency content. Because of
this technology, the signal can be carried through longer cables in harsher
noise environments, giving you flexibility in your sensor and data-acquisition
system siting.
