VW Piezometer VWP-3000 Series
The VWP-3000 Series Vibrating Wire Piezometer is engineered for long-term, high-accuracy measurement of pore water pressure in geotechnical, civil, and mining applications. Built with a robust stainless-steel body and a highly stable vibrating-wire sensing element, the VWP-3000 Series delivers dependable performance in challenging environments where precise groundwater monitoring is critical.
Designed for embankment dams, tunnels, foundations, slopes, tailings facilities, and deep boreholes, the instrument provides reliable data even under high pressure, temperature fluctuations, and long-term loads. Its vibrating-wire technology minimizes signal drift and maintains accuracy over extended monitoring cycles, making it an ideal choice for long-duration projects.
The sensor converts pore pressure changes into frequency shifts, ensuring excellent noise immunity and compatibility with automated data loggers for real-time data acquisition. Optional thermistor integration enables simultaneous temperature measurement, supporting more comprehensive geotechnical analysis.
With its combination of durability, precision, and ease of integration, the VWP-3000 Series is widely used by engineers and asset owners who require consistent and traceable pore pressure data to support design verification, risk mitigation, and early-warning systems in critical infrastructures.
