In December 2014, Campbell Scientific released the CRVW3 Vibrating Wire Datalogger. The new CRVW3 consists of a datalogger mounted in a 9-inch-by-9.5-inch enclosure, with either a rechargeable or alkaline battery. Designed exclusively for vibrating wire measurements, the CRVW3 has three channels for directly connecting vibrating wire sensors (no interface required). It arrives field ready and is configured to monitor vibrating wire sensors; no coding by users is needed. An optional internal radio supports wireless routing communication.
The CRVW3 uses Campbell Scientific’s patented vibrating wire spectral-analysis technology (VSPECT) to provide better vibrating wire measurements. VSPECT greatly reduces signal noise, delivers the highest resolution measurement (less than 0.001 Hz) for vibrating wire sensors, and provides diagnostic information about the measurements.
Vibrating wire sensors benefit a wide variety of structural, hydrological, and geotechnical applications, and our VSPECT products make better measurements for these applications. The CRVW3 promises to be a valuable new addition to our VSPECT family.
