Vibrating wire piezometer for pore pressure and geotechnical instrumentation
He EPP-30V Heavy Duty Vibrating Wire Piezometer Encardio Rite is a pore pressure sensor designed for measuring the interstitial water pressure and the control of water table in applications of geotechnical instrumentation, Civil works, mining and hydraulic infrastructure.
This piezometer for geotechnical monitoring It uses vibrating wire technology to convert applied pressure into a frequency signal, enabling stable and reliable measurements in installations with long cable runs and demanding environments. It is a suitable solution for projects requiring continuous monitoring of water behavior in the ground.
EPP-30V Vibrating Wire Piezometer for Geotechnical Monitoring
The model EPP-30V It is designed to offer long-term durability and stability under real-world field conditions. Its robust construction, vacuum-sealed design, thermal compensation, and integrated thermistor make it a suitable choice for buried applications and automated data acquisition systems.
What is a pore pressure sensor used for?
A pore pressure sensor It is used to monitor pore water pressure in soils, fills, retaining structures, and underground works. This information is key to evaluating the hydraulic behavior of the ground, soil consolidation, and the stability of geotechnical infrastructure.
- Dams and hydraulic structures: control of the groundwater line, subpressures and water behavior in the ground.
- Slopes and hillsides: monitoring of interstitial pressure conditions that may affect stability.
- Tunnels and excavations: control of the groundwater level and the hydraulic behavior of the terrain.
- Foundations and consolidation: monitoring pore pressure dissipation processes in soft soils.
- Wells and boreholes: monitoring of groundwater levels.
Advantages of the vibrating wire piezometer
- Stable long-term measurement in geotechnical monitoring applications.
- Good signal integrity in installations with long cable distances.
- Compatibility with dataloggers and data acquisition systems.
- Robust construction for harsh civil engineering and mining environments.
Keys to a correct installation
The reliability of a vibrating wire piezometer It does not depend solely on the sensor, but also on proper installation based on the terrain, depth, and construction conditions.
- Filter saturation: necessary to avoid delays in response.
- Correct range selection: depending on depth and expected pressure.
- Cable protection: against humidity, mechanical damage and interference.
- Integration with datalogger: for manual campaigns or continuous monitoring.
