Vibrating wire piezometers are absolute pressure transducers aimed to measure soil pore pressure.

Applications include control of over-pressure in silt and clay soils, measurement of permeability and hydraulic gradients in dams and water pressure evaluation for landslide safe-rates. Output signals, suitable for transmission over long distances, are easily read and automated.

Multipoint Piezometer is a string of Vibrating Wire pressure transducers connected through a single multicore cable that allow to have until No.8 measuring point into one borehole. They are available with several full scale and with both HAE and LAE filters.
