The itmsoil Vibrating Wire Piezometer is designed for accurate and long term measurement of pore water pressures in fully or partially saturated soil and rock.
The Standard Vibrating Wire Piezometer provides accurate measurement of pore water pressures in fully or partially saturated soil.
The transducer is made from high quality 316 grade stainless steel and designed to handle pressure ranges from -50 to 4000 kPa. It incorporates an over voltage surge arrestor that oﬀers protection from a lightning strike
The piezometer may be ﬁtted with either a low air entry sintered steel or high air entry ceramic ﬁlters. A coned nose piece is available for push in installations. An integral thermistor for temperature monitoring is included.
The Standard Vibrating Wire Piezometer is designed for the accurate measurement of pore water pressures in fully or partially saturated soil.
The piezometer tip has an integral porous filter element containing a diaphragm type Vibrating Wire pressure transducer. A cable connects the transducer to a read-out, terminal unit or data logger.
The readout can display either frequency based units, or on inputting the instrument calibration factor, it can also display engineering units.
Piezometers are used in geotechnical, environmental, and hydrological applications. They can be installed in boreholes, placed in ﬁll materials or open wells to measure water levels or pore water pressures to enable engineers to verify design assumptions and control placement of ﬁll. With a nose cone ﬁtted the piezometer can also be pushed into soft ground with a CPT rig.
