Soil Pressure/Volume Control

The PCP-200 is a tabletop, manually-operated pneumatic panel that controls confining, pore, and back pressure in soil specimens, compliant with ASTM D3999-91 and D5311-92. It has a 1,000 kPa capacity and can be upgraded to computer control.

The PCP-2000 features a pressure panel, large cabinet, and two or three stainless-steel pressure-volume intensifiers for controlling confining, pore water, or pore air pressure. Intensifiers come in 1, 2, or 3.5 MPa capacities with 300, 800, or 2,000 cc volumes and can be controlled hydraulically or pneumatically. They support dynamic pressure application up to 10 Hz and allow for pre-programmed stress-strain paths.

The ePVC Series Standalone Pressure/Volume Controllers independently manage hydraulic pressure or flow with standard 100‐240 VAC power, requiring no hydraulic power. These controllers offer closed-loop servo-control, large volume capacity, and precise measurements to avoid errors from gear backlash. The ePVC includes PC and mobile interface programs (iOS, Android, Windows) and can link multiple units via CATS software for synchronized control in various tests. Models are upgradable for continuous flow with no pressure spikes.
