Vibrating
wire piezometer is a highly useful device designed to measure soil pore
pressure. The device has a vibrating transducer and signal cable driven by wire
pressure. It is used by either installing it in a borehole or embedding in a
fill or suspending in a standpipe. A portable readout provides the readings
which are very accurate and error-free when done rightly. A data logger can
also be used for the purpose.
The
instrument responds amazingly well to changes in pore pressure and can be used
in all typed of soils. The measurement is...

Applications of Vibrating Wire Piezometer
A VibratingWire Piezometer measures water level for excavation walls, checks slope
stability, measures pore pressure in embankments and soft ground, checks and
monitors flow and leak of underground water in dams and banks.
The instrument comes with a high tensile
steel wire that is attached to a diaphragm in contact with water pressure at
one end and a fixed anchor on the other end. The wire is plucked electrically with
resonant frequency of vibration at a proportion to tension in the wire. This frequency leads to an alternate current
in...

Uses of Vibrating Wire Crackmeter in Concrete Structures
Monitoring and measuring of movements across surface cracks and joints
in concrete structures or rock is done by the Vibrating Wire crackmeter. Monitoring applications include brick and stone buildings, bridges and dams,
construction joints, pipelines and joints in concrete and rocks. Made of high
quality steel, the sensor provides accurate and reliable readings for long term
monitoring.
It is fully waterproof and is ideal for both manual and remote
monitoring. The sensor is fitted across a joint or crack and keeps a track...

Examine Strain Movements with Vibrating Wire Strain Gauge
Instruments used to check the short and long term strains on tunnel linings, arches, piles, struts, dams, rock surfaces and many other such structures are called vibrating wire strain gauge. The device comes with a tensioned steel wire enclosed in a stainless steel tube. The steel wire is supported by two blocks at the two ends. Electromagnetic coils located close to the wire when excited induce the wire to swerve at high speed.
