Vibrating Wire Earth/Soil Pressure Cells
The model VWE series vibrating wire soil/earth pressure cells is an embedded soil pressure sensor, which is mainly used to measure the stress of soil inside structures such as earth-rock dams, soil lifts, slopes, roadbeds, retaining walls and tunnels. The main parts of the sensor are made of special steel, which can be used in harsh environments. It has excellent performance, good precision and sensitivity, excellent waterproof performance, corrosion resistance and long-term stability, etc. After the cable protection measures are perfected, it can be directly buried in the compacted soil which has higher requirements on the instrument.
