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.

Benefits and Features
