Hydraulic Pressure Control Systems

Supports the following standards: ASTM D2850, D2166, D4767, D5084, AASHTO T296, T297, T208

Humboldt’s stand-alone, hydraulic-pressure controllers are designed to provide control of the triaxial testing function from a compact, small-footprint device. These hydraulic-pressure controllers eliminate the need for pneumatic/water bladder systems, and remove many of the problems inherent with these systems. The controllers consist of hydraulic pistons, driven by low-friction stepper 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 pressure control with real-time pressure and volume change readings.

These hydraulic-pressure controllers are available in both high-pressure 500psi (3500kPa) and standard pressure 150psi (1034kpa) models. They provide a volume of 250mL/channel, and can maintain a desired pressure within 0.35 kPa (0.05 psi) while monitoring volume changes within 0.001 cc.

Automated, Triax-Control Pressure Controller
The Auto Triax-Control Pressure Controller (HM-5820) is an automated, hydraulic pressure/volume controller designed to handle saturation, consolidation of a triaxial test sample, as well as permeability tests. It can also perform the triaxial shear function with the use of its integral HM-5020 load frame eliminating the need for a stand-alone load frame. It is available in two configurations; one for high-pressure applications: 0-500psi (3500kpa), and a standard pressure model for 0-150psi (1034kpa) applications.

The HM-5820 provides an accurate and compact configuration for performing triaxial and permeability tests without the need for separate distribution panels, while simplifying the tubing and control 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.

Automated, Hydro-Control Pressure Controller
The HM-5810.3F is an automated, hydraulic pressure/volume controller designed to handle saturation, consolidation of a triaxial test sample, as well as permeability tests. The HM-5810 provides an accurate and compact configuration for performing triaxial and permeability tests without the need for separate distribution panels, while simplifying the tubing and control cable setup. It is available in two configurations; one for high-pressure applications: 0-500psi (3500kpa), and a standard pressure model for 0-150psi (1034kpa) applications. By using the integral staging platform for triaxial and permeability cells, the HM-5810 provides an extremely compact and organized setup for testing.

To perform the shear phase of a triaxial test, you will need to add an elite-series load frame. The HM-5810 provides three (3) analog input channels (24-bit) for measuring pressures and three (3) encoder inputs for measuring volumes. The HM-5810 is built around Humboldt’s integral, data logger with its touch-screen control, allowing the HM-5810 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.

Hydraulic Pressure Controller
The HM-5250.3F is a fully-automated hydraulic pressure controller, which is highly accurate up to 500psi (3500kpa) in pressure and 250ml in volume. It is designed specifically for geotechnical laboratory triaxial testing (UU, UC, CU and CD) and provides control and monitoring of cell pressure, back pressure, pore water measurement and volume change when used with our Elite-series load frames. It is available in two configurations; one for high-pressure applications: 0-500psi (3500kpa), and a standard pressure model for 0-150psi (1034kpa) applications.

The HM-5250 provides two (2) analog input channels (24-bit) for measuring pressures and two (2) encoder inputs for measuring volumes. In stand-alone mode, this pressure controller provides a 7" (178mm) touch-screen controller. This waterproof, touch screen provides colorful, at-a-glance monitoring of testing functions without the use of a computer. Operator can see all the data in several formats at the controller while the test is running. The test data can be viewed simultaneously or downloaded later to a computer in the lab, in the next room or at a different location, while also providing report generation capabilities from within Humboldt’s NEXT software or our enhanced test-specific modules.
