The soil uniaxial and triaxial (soil infiltration) pressure volume control system is a universal water pressure source and volumetric gauge. Mainly used for teaching soil mechanics laboratory. A stepper motor and screw driver drive the piston to directly compress water. Pressure is regulated through closed-loop control. By calculating the number of steps of the stepper motor and measuring the constant volume change pressure, 1mm3 (0.001cc) can be measured.

The soil triaxial (soil infiltration) pressure volume controller is a device that can replace conventional soil mechanics laboratory pressure sources and volumetric displacement drainage devices. Firstly, the device has its own computer interface that can be directly controlled through a computer.

 

Advantage

It is also an ideal saturation and drainage system that can measure the volume change of water in the sample. In addition, when the pressure and volume exceed the range, the controller has an automatic protection function.
