一、Summary
Automatic cross plate shear tester is a kind of indoor geotechnical test instrument used to measure the shear strength of soft soil or sensitive clay. It can measure the undrained strength of undisturbed soil at different depths, and also measure the sensitivity of soil.
二、Main technical indicators
Sample cylinder specifications: φ 100mm(outer diameter)×H177mm.
Cross plate specifications: φ 12.7mm× H25.4 mm, φ 25.4mm× H50.8 mm, φ 38.1× H76.2 mm.
Strain rate: 0.001 ~ 180°/min, infinitely variable speed.
Torque sensor: 0-30 N·m, accuracy 0.3%F.s, resolution 0.1N ·m, temperature impact: < 0.5%FS/10℃ (0-45 ℃ range), overload protection.
Cross plate area ratio: < 15%.
Equipped with 480*270 HD LCD touch screen, real-time display of torque and other test parameters, supporting touch keys control operation, touch keyboard control can also be controlled by software; High-speed network communication interface and computer communication; Data is stored in the collector in real time and can be run offline.
The collection and processing software supports Win8/10 operating system, automatic collection and control, data can be exported to Excel file, draw shear strength curve of soil sample and calculate strength value.
A set of computer control, acquisition, processing system.
