WebThe Vibrating Wire Piezometer (VWP) is the industry standard in pore pressure monitoring. Constructed from high-quality 316 stainless steel, the VWP is capable of performing with long cable runs with an operation longevity for many years. WebThe vibrating wire transducer inside the piezometer converts water pressure to a frequency signal via a diaphragm, a tensioned steel wire, and an electromagnetic coil. The transducer is constructed so that a change in water pressure on the diaphragm causes a change in the tension of the wire.
WebThe main difference between piezometers is the instrument used to measure the diaphragm’s deformation. Vibrating wire piezometer. In a vibrating wire piezometer, or VWP, a wire is attached to the diaphragm on one end and anchored to the instrument on the other. This wire is electrically “plucked” with a magnet, and the effects of the ... WebJul 23, 2024 · Vibrating wire piezometers are used to monitor pore-water pressure in soils.
