Keeping the Noise Down: New Technology is Intended to Make Vibrating Wire Sensors More Reliable

In most types of structural health monitoring, from statues, light towers, slopes, tunnels, dams, buildings, to bridges, vibrating wire sensors have been used. Vibrating wire sensor benefits include the ability to be reused from one project to another, ease of mounting, temperature compensation, and long-term stability. To date, random or intermittent noise source-generated erroneous measurements have been the main downside of vibrating wire sensors. The author discusses Campbell Scientific's new vibrating wire technology using sensor types less susceptible to noise. Improved noise immunity will allows professionals to take advantage of vibrating-wire measurement technology's benefits for structural monitoring and build confidence in the technology.
