These solutions begin with the choice of a pressure control system. Humboldt provides pri- marily four different pressure controllers. Auto Hydraulic Pressure Control Triaxial System This system features a hydraulic-powered system, which provides the option for high-pressure of up to 500psi (3500kPa), as well as the standard pressure of 150psi (1034kPA). These controllers consist of hydraulic pistons, driven by low-friction stepper motors, managed through a closed-loop feed- back system with built-in data acquisition and a 7" touch-screen color control panel. FlexPanel Pressure Control Triaxial System Humboldt’s FlexPanel pressure control option eliminates the use of the air/water bladder inter- face concept of pressure control in lieu of its high- ly-accurate burette system. Humboldt FlexPanels provide an accurate and easy-to-operate solution for controlling compressed air, water, de-aired water and vacuum. Auto Hydraulic Pressure Control Triaxial System Humboldt’s stand-alone, hydraulic-pressure con- trollers are designed to provide control of the tri- axial testing function from a compact, small-foot- print device. These hydraulic-pressure controllers eliminate the need for pneumatic/water bladder systems, and remove many of the problems inher- ent with these systems. The controllers consist of hydraulic pistons, driven by low-friction step- per motors, managed through a closed-loop feedback system with built-in data acquisition and a 7" touch-screen color control panel. The user-friendly, touch-screen panel provides pres- sure control with real-time pressure and volume change readings. These hydraulic-pressure controllers are avail- able in both high-pressure 500psi (3500kPa) and standard pressure 150psi (1034kpa) models. They provide a volume of 220mL/channel, and can maintain a desired pressure within 0.35 kPa (0.05 psi) while monitoring volume changes within 0.001 cc. The HM-5820 and HM-5810 controllers provide a single, control unit to handle the saturation, consolidation and permeation of triaxial tests. In addition, The HM-5820 also provides an integral triaxial shear function for complete triaxial testing. The HM-5250 provides the saturation and consol- idation functions for triaxial tests, and pairs well with either the HM-5810 or HM-5820 for added cell setups, or it may be augmented with a simple control panel for permeability and an Elite-series load frame for the shear function.

Humboldt FlexPanels provide an accurate and easy-to-operate solution for controlling compressed air, water, de-aired water and vacuum without the need for air/water bladder interfaces to produce the pressures nec- essary for triaxial testing. FlexPanels utilize a set of three burettes to control cell, top cap and base pedestal pressures. This extremely versatile pressure system controls the pressure, water, de-airing tank and vacuum from a single panel. The three burettes allow for the control of the cell pressure and the back pressure for each cell. They can monitor volume change in the sample and can be used to measure the flow of water through the sample for permea- bility testing. This is a benefit to using FlexPanels over the air/water bladder system. Like our other control systems you can run UU, CU and CD triaxial tests with FlexPanels. They are available in one or three-cell configurations and can be used in multiple configurations. All you need to do is add cells and the other appropri- ate equipment to handle your needs. Humboldt’s FlexPanel pressure control system also uses our NEXT software and our enhanced test-specific modules, which monitors, controls and reports test data, and, the highly-regarded HM-5030 load frame with its built-in, 4-channel data acquisition controller for stress, strain, pore water pressure and volume change measurement. The system can also be configured for use with our triaxi- al-specific load frame, the HM-5020 See page 138 for a complete component list for the FlexPanel Pressure Control Triaxial System.

It can also perform the triaxial shear function with the use of its inte- gral HM-5020 load frame eliminating the need for a stand-alone load frame. It is available in two configurations; one for high-pressure applica- tions: 0-500psi (3500kpa), and a standard pres- sure model for 0-150psi(1034kpa) applications. The HM-5820 provides an accurate and compact configuration for performing triaxial and permea- bility tests without the need for separate distribu- tion panels, while simplifying the tubing and con- trol cable setup. And, with its integral load frame, the HM-5820 provides an extremely compact and organized setup. The HM-5820 provides four (4) analog input channels (24-bit) for measuring pressures and load, one (1) analog input channel (12-bit) for measuring displacement and three (3) digital encoder inputs for measuring volumes. The HM-5820 is built around Humboldt’s integral, data logger with its touch-screen control, allowing the HM-5820 to be used as a stand-alone device, capable of full test control and data logging. It can also be controlled by a networked computer at any location with access to the network.

The FlexPanel’s simple, straight-for- ward configuration, with its integral burettes pro- vides a condensed/compact design that takes up less counter space than competing systems with air/water bladders. The long, narrow burette design of Humboldt’s FlexPanels provide faster test processing times when compared to larger, shorter burette sys- tems, while providing the same volume. This is due to the reduced amount of meniscus formation in the narrower burettes, which allows the water level to drop faster, resulting in faster readings. In addition, the use of longer/narrower burettes and a scale graduation of 0.02ml, also provides an easier-to-read and more accurate scale. FlexPanels also feature a bias regulator and bridge. The bias regulator maintains the differen- tial pressure when confining and back pressures are increased. The bridge delivers simultaneous control of base and top pressures through the use of just one regulator. This feature minimizes operator time and reduces the margin of error in opening and adjusting regulators during a test. The Humboldt FlexPanel system is comprised of 5 separate panel configurations, which can be grouped together to accommodate from 1 to 6 cell setups. Fast and Easy Setup and Operation Humboldt FlexPanels make setup fast and easy with clearly labeled ports and quick-connect hookups. Operation is just as easy with clearly labeled controls, large gauges and easy-to-read burette markings. All inlets and outlets utilize quick-connects to ensure fast, accurate setup to permeameter cells, as well as air, water and drain hook ups. Fittings, tubing and connectors are supplied with each unit. All FlexPanels are designed to handle air pressures up to 150 psi. Humboldt FlexPanels Features: Humboldt FlexPanels are constructed of light- weight aluminum for long, rust-free life. Flex- Panels provide an accurate and easy-to-operate solution for controlling compressed air, water, de-aired water and vacuum without the need for air/water bladder interfaces to produce the pres- sures necessary for triaxial testing. FlexPanels utilize a set of three burettes to control cell, top cap and base pedestal pressures. This extremely versatile pressure system controls the pressure, water, de-airing tank and vacuum from a single panel. The three burettes allow for the control of the cell pressure and the back pressure for each cell. They can monitor volume change in the sam- ple and can be used to measure the flow of water through the sample. FlexPanels can manually measure volume change in a triaxial test sample without the use of a vol- ume change apparatus, a distinct benefit when compared to air/water bladder systems. How- ever if you need to do data acquisition a volume change apparatus would then be required. •Bias pressure regulator allows simultaneous control of confining and 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 valves •Bridge feature delivers simultaneous control of base and top pressures by adjusting one pressure regulator simplifying testing.SOIL MECHANICS Cell Components & Accessories www.humboldtmfg.com • 1.800.544.7220 • 708.468.6300 137 HM-2315 Volume Change Apparatus Shown with HM-2310.10 Transducer and HM-2310BR Bracket.
