FlexPanels - 1-Cell Control Panel

Supports the following standards: ASTM D4767, ASTM D5084, ASTM D6035, ASTM D7181, BS 1377 Part 6 1990

The HM-4150 1-cell, 3-burette control panel provides pressure controls and readouts for permeability and triaxial applications. It can control all the functions of a single cell, however with the addition of Auxillary Panels it can control the operations of up to five (5) cells.

Controls include: a digital, readout pressure meter, a pressure supply gauge, a master pressure regulator, a vacuum supply gauge, a master vacuum regulator, de-aired water tank controls, tap and de-aired water supply outlets and pressure and vacuum outlets.

FlexPanels can manually measure volume change or permeability in a triaxial test sample without the use of a volume change apparatus, a distinct benefit when compared to air/water bladder systems.

  • Bias pressure regulator allows simultaneous control of confining
  • back pressures, while maintaining a constant differential
  • Longer Burette and 0.02ml graduation give more accurate results, better productivity, and faster turnaround
  • Uses no-volume-change Swagelock valves
  • Bridge feature delivers simultaneous control of base and top pressures by adjusting one pressure regulator simplifying testing
  • Quick-connect hookups for fast and reliable set up.
  • Master control panel houses digital pressure readout for the controlling pressure, inlet vacuum regulator & gauge, inlet pressure regulators & gauge, de-aired water tank controls, tap & de-aired water supply outlets, and pressure & vacuum outlets
  • Comply with ASTM D5084; BS 1377 Part 6 1990.
