FlexPanel 2 -Cell Control Panel HM-4160 2-cell, 6-burette control panel provides pressure controls and readouts for permeability and triaxial applications. Controls all the functions of two cells, however with the addition of Auxiliary 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 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.

FlexPanels, 2-Cell Auxiliary Panel The HM-4160A auxiliary panel provides additional sets of burettes for 2 cells, which can be used to expand the capacity of a system. Each set of three (3) burettes provide the controls necessary for another cell to be used. The HM-4160A provides two (2) sets of (3) burettes. Humboldt recommends any combination of up to five (5) burettes sets can be used with each control panel.

FlexPanels, 1-Cell Auxiliary Panel The HM-4150A auxiliary panel provides additional sets of burettes for 1 cell, which can be used to expand the capacity of a system. Each set of three (3) burettes provide the controls necessary for another cell to be used. Humboldt recommends any combination of up to five (5) burettes sets can be used with each control panel.

Permeability Cells w/ Caps and Bases HM-4188B permeability cells are constructed of high-quality materials throughout for long-lasting performance. The cell top and base are precision machined from 6061 T6 aluminum and black anodized for a durable finish. To facilitate sample setup, the chamber and cell top can be quickly and easily removed by loosening the three knobs that hold the upper assembly to the base. The clear acrylic chamber provides a working pressure of 150 psi (1,000 kPa) and is tested to 250 psi (1,700 kPa).

The cell has five, no-volume-change, valves aligned along the front of the cell for maximum convenience.

Two valves handle top drainage, two valves handle bottom drainage, and one valve handles filling/emptying and providing confining pressure to the cell.

De-Aired Water System The HM-4187A.3F produces 8-liter batches of de-aired water without the use of heat. Combined mechanical agitation and vacuum evacuation removes gasses at much higher rate than conventional heat-boiling methods. Will de-air water to less than 0.5 pph dissolved oxygen in 4 minutes. Requires a vacuum pump, 1/55hp motor 110V, 60Hz. 7.5 x 7.5 x 20" (190 x 190 x 508mm).

Minilogger Designed for applications where it is desired to add data acquisition capabilities to older or simpler testing equipment that does not have data acquisition capabilities. These data loggers provide advanced data acquisition and reporting functions effectively updating the equipment they are used with.

The HM-5320-F provides four individual, 24-bit analog to digital converters with an instrumentation excitation supply of 10 VDC. This analog data logger is ideal for use with instruments, such as pressure transducers, load cells, and strain transducers. It provides data storage for 1000 readings per channel.

MISC Parts Miscellaneous parts shall include all required, hoses, piping, tubing, regulators, fittings, valves, membranes, and ‘O’ rings, etc. for new and fully functioning permeability testing area into the Fort Worth Soil Mechanics Laboratory.

Equipment Setup and Training Complete equipment setup, including setting the control panels and auxiliary panels. Connecting the compressed airlines (provided by the laboratory) and de-airing tanks to the distilled water source (provided by the laboratory) and the perm boards. All of the necessary tubing internally within the boards and to the permeability cells. Setup should be complete, so the permeability equipment is functional.

Training will be for how the control board and auxiliary panels function, how the permeability cells function and any common issues to avoid.
