Introduction

The strain controlled triaxial apparatus is designed and manufactured according to GB/T50123-1999 GB/T50123-2019 "Standard for Soil Test Methods", and all performance parameters fully comply with relevant specifications. This instrument is used to measure the shear strength, deformation, and pore water pressure of soil samples under equal strain loading. This system can perform unconsolidated undrained tests (UU), consolidated undrained tests (CU), consolidated drained tests (CD), etc.

This instrument mainly consists of three parts: measurement and control system, loading system, and accessories (content force ring, pressure chamber, saturator, membrane bucket, split mold, soil cutter, compactor, etc.)

v NOTE

The cutting rate is infinitely adjustable throughout the entire range, and the high-resolution full-color LCD screen displays the speed and motor status in real-time

The measurement accuracy of confining pressure, back pressure, and pore pressure (hereinafter referred to as pore pressure) can reach 0.001Mpa, and it can be displayed in real-time on an ultra large touch screen

The confining pressure and back pressure can be automatically controlled, and the control accuracy can be adjusted, with a maximum of 0.001Mpa

Product Features

v The core control system of the instrument measurement and control system adopts a high-speed 32-bit ARM microcontroller, with high-speed sampling and computing capabilities to ensure accurate acquisition and display of various data during the test process.

v The measurement and control system adopts a large screen color touch LCD screen, a friendly and intuitive human-computer interaction interface, simple and easy to operate touch settings, and Jing Yiqiu Jing's software design, providing users with an unimaginable user experience.

v The loading system is driven by a servo motor with a continuously variable shear rate. The display uses a 3.5-inch color screen with a friendly and intuitive interface. The motor is controlled by all metal mechanical buttons, and commonly used speeds can be quickly selected and set. Users can also customize the speed for quick adjustment.

v The entire system does not require any external pressure source such as an air compressor, and achieves hydraulic control on its own, with stable performance and meeting the needs of various triaxial tests.

v The instrument pipeline is simple and easy to operate, and the on/off status of valve fittings is easy to distinguish. The pressure chamber has high compressive strength, and the friction coefficient of the pressure rod is small, which maximizes the elimination of the influence on the test.
