DESCRIPTION
The vibrating settlement cell measures settlement and thrust in soil and rock fill. The use of measurement data from the cell can help control further displacement.
The cell consists of a vibrating wire pressure transducer connected through a pair of water-filled nylon tubes to a hydraulic potentiometer located on stable ground.
Vertical movement of the cell relative to its reading location results in a change in liquid pressure within the chamber, which is recorded in meters of water and translated into the amount of settlement or load.
The vibratory settlement cell can take measurements beneath concrete and earth structures in locations that are inaccessible to other types of instruments.
FUNCTIONS
- 15m and 30m ranges available.
- Manhole, trench and low profile types available.
- No vertical rods or pipes to interfere with construction.
- Twin liquid lines allow recirculation of water through the system after installation.
- Does not require access above the sensor to acquire data.
BENEFITS
- Accurate and repeatable readings over long cable lengths.
- Long life, long-term stability and reliability.
- Surge protector prevents electrical damage.
- Connecting cable is firm, shielded and flexible.
- Measurements are not affected by lateral movements.
