This tester is used to determine the subsidence value of the roadbed under the static load, so as to evaluate the bearing capacity and deformation of the roadbed.
It is suitable for monitoring the quality of foundation construction of railways, highways, airports, urban transportation, ports, terminals and industrial and civil buildings subject to static loads.
After the ground is loaded and unloaded for the first time through the circular load bearing plate and the loading device, the second load is performed, and the measured stress σ of the load bearing plate and the corresponding center settlement value S of the load bearing plate are used to calculate The values of the deformation modulus Ev2 and Ev2 / Ev1.
Sensors and some components are imported, with high test accuracy and more reliable test data;
Oil cylinder and manual pump imported from abroad, achieve outstanding pressure control and voltage stabilization performance;
The displacement acquisition device adopts heavy-duty materials and a three-point support design, which has strong anti-seismic and wind-proof capabilities to ensure accurate data;
LCD display in English interface, with backlight, it has better visibility in various environments.
Ev1, Ev2 and Ev2 / Ev1 are automatically calculated and display curve.
The hand-held main unit is equipped with a Bluetooth mini printer and directly printed on site to ensure the test results are accurate and objective.
USB transmission interface is convenient for connection with computer.
Voice prompt function makes operation more convenient.

Plate bearing test is used in earthworks and soil foundations to evaluate the composition and consequent deformability of the soil. This gives an indication of the total load capacity of the soil under test.
Also used in road construction engineering.
