Digital display and equal strain control type direct shear instrument adopts electronic digital technology to transmit data. The software of soil test data processing and acquisition system automatically collects, records and stores test data in real time. Compared with previous instruments, it saves the trouble of manual data reading and improves the working efficiency.
The digital display constant strain controlled direct shear instrument is used to measure the shear strength of soil. Usually, a specimen is used to apply shear force under different vertical pressures to shear, so as to obtain the shear stress at the time of failure. The coefficient of shear strength, Angle of internal friction and cohesion are determined according to Coulomb's law.
The digital display constant strain control direct shear instrument is suitable for slow shear, fast shear and repeated shear tests.
Instrument characteristics
1. Special earth test data processing and acquisition system test process automatic collection, record and store vertical displacement, force value instrument data.
2. The test process saves labor, time, improve the efficiency of the test.
3. Lever ratio amplification,.. The weight and the labor intensity of the weights.
4. Compact structure, reliable, stable and easy to use.
5. The instrument increased the shearing box back limit function, so that the shearing box back to the designated position after automatic stop, enhanced the protection function.
6. LCD display set shear speed, shear deformation.
7. With the hand shear function, can be in the case of power failure, does not affect the test.
