The earth pressure gauge is suitable for long-term measurement of the compressive stress of the soil in the earth-rock dam, earth embankment, slope, roadbed and other structures.
The earth pressure gauge is suitable for long-term measurement of the compressive stress of the soil inside the structure such as earth-rock dam, earth embankment, slope and roadbed.
When the soil stress in the measured structure changes, the earth pressure gauge induction plate synchronously feels the change of stress, and the induction plate will produce deformation, and the deformation will be transferred to the vibration string into the change of the stress of the vibration string, thus changing the vibration frequency of the vibration string. The electromagnetic coil excites the vibration string and measures its vibration frequency. The frequency signal is transmitted to the reading device through the cable to measure the compressive stress value of the measured structure. At the same time, the temperature of the buried point can be measured synchronously.
