TC5001

V.W. Total Pressure Cell is installed between retaining wall and soil and then monitor total earth pressure caused by loads of surrounding grounds.

Once the total pressure of the cylinder cell is given or load of the surrounding grounds is added, the fluid which fills the inside of the cylinder cell gets pressure and this pressure is delivered to the sensor.

At this time, once pressure is given to the diaphragm of pressure sensor, tension of vibrating steel wire is changed then plucking coil senses the frequency of the changes. Once the primary coil generates a frequency signal on the vibrating wire, then the secondary coil sends the frequency to a measuring instrument.

The measured frequency is converted into pressure through calibration factors.

Monitoring strain of Slurry Walls, Concrete piles, Caissons, Osterberg pile tests, other concrete structures.

Observe the bend of strut, flexure of bolt, crack to judge the stability comparing with the axial force and stress, temperature of strut, earth anchor, temporary structures and presented allowance axial force and stress of embedded steel.

Installed between retaining wall and soil, then monitor total earth pressure caused by loads of surrounding grounds.

Installed in Core level of stone dam in center core type then measure transition degree of stress and then install at the higher stiffness filter level than core level. Measure the added gravity loads in filter level.

When city excavation, measure the change of the earth pressure under installation at the rear of earth retaining wall or underground structure.
