Triaxial Control Panels: Auxiliary for Permeability Tests

Introduction and Key Features

The Auxiliary Triaxial Control Panel is a cutting edge system for triaxial and permeability. It’s an essential component in soil testing with many innovative features that make the testing process easier. With its advanced design the control panel gives accurate and reliable results, it’s a must have for both research and commercial labs. The system can control air and fluid pressures with high precision so every test is done under optimal conditions.

Overview of the Auxiliary Triaxial Control Panel

The Auxiliary Triaxial Control Panel works in conjunction with the Master Control Panel to control additional triaxial or permeability test cells. It has a logical layout and quality components for easy operation and measurement. The panel controls air and fluid pressures precisely making it ideal for commercial labs. By integrating with the Master Control Panel it expands the system’s capacity to test multiple samples at the same time. This flexibility allows labs to meet increasing testing demands without compromising on accuracy or efficiency.

Key Features and Innovations

The Auxiliary Triaxial Control Panel has many key features including factory installed digital readout for precise pressure control, master pressure regulators and zero displacement ball valves for positive shutoff. The panel also has burettes for flow measurement and a central point for supply connections for air, water and drain. It’s also easy to fill and measure volume change making it efficient for triaxial testing. It meets and exceeds the rigorous standards for soil testing and gives the user a user friendly interface.

The Triaxial/Permeability Additional Control Panel lets you add additional triaxial or permeability test cells economically for more productivity. The Additional Panel attaches to the Master Control Panel and uses its digital pressure readout to show confining and cell pressures and control air pressures. The Additional Panel has the same precision master pressure regulator, valves, reservoir and burrette assemblies as the Master Control Panel but does not have a Digital Pressure Supply Gauge. The de-airing tank allows for de-aired water preparation for sample saturation and testing.

Triaxial and permeability is in high demand for structural performance verification and environmental regulations compliance. These modular components can be added to new or existing equipment when building a system to meet your needs for measurement of pore pressure and control loading rates. Triaxial tests are vital for the accurate assessment of materials.

Overview and Benefits

The Master Control Panel is the complete solution for triaxial shear and flexible-wall permeability testing. It has a digital readout for setting test cell pressures during various testing phases, emphasis on precision and ease of use. The vacuum in the pressure control systems maintains precise conditions during testing. Precise control, logical layout and quality components for accuracy and ease of use. The panel controls air and fluid pressures in the test cells and is the central point for air, water and drain connections. Powder coated aluminum frame, built to last and logical layout for easy use. So you can do flexible wall permeability testing with confidence knowing you have control of everything.

What is Triaxial Control Panels

Triaxial control panels are essential components in triaxial and flexible wall permeability testing of soils. Effective stress during various testing phases including saturation and consolidation is crucial to get accurate measurements and results. These panels provide precise control over air and fluid pressures in test cells for accurate and reliable test results. The master control panel is the central hub, controls air and fluid pressures and manages supply connections for air, water and drains. By adding optional add-on panels you can control multiple test cells, the system is highly adaptable to various testing needs. This flexibility ensures that whether you are doing triaxial shear tests or flexible wall permeability tests you have the precise control for reliable results.

Key Components and Operating Principles

The key components of a triaxial control are:

• Master Pressure Regulator: The master pressure regulator is used to set and control pressures during saturation, consolidation and testing, to maintain precise pressures. Back pressure is controlled through regulators within the testing equipment to manage effective stress and testing conditions.

• Zero-Displacement Ball Valves: These valves provide positive shutoff and control over air and fluid pressures to prevent any displacement.

• Burettes: For flow measurement, located inside storage chambers with extra capacity for accurate flow measurement.

• Pressure Readout: Displays the pressure readings, some panels have a factory installed digital readout for easy and accurate monitoring.

• Upper Half Controls: Regulates air pressure to the specimen chamber to maintain air pressure at desired level.

• Lower Half Controls: Manages water supply to control fluid pressures.

Technical and Pressure Control Options

The Master Control Panel is available in two versions: psi pressure readout and kPa pressure readout. The panel has a factory installed digital readout to set cell and sample pressures and can be connected to an additional panel to control triaxial or permeability cells. Technical specifications:

• Pressure: Pressure control

• Cell pressure: one regulator

• Sample pressure: one regulator

• Air controlled by precision regulators

• Flow measurement: two 50cc burettes with 0.1cc graduations and two 4cc pipettes with 0.008cc graduations

• Zero-displacement ball valves: shutoff

• Effective cell pressure: one regulator

• Permeability test chambers: can be connected to the panel for measurement

An air compressor is required for confining pressures in triaxial shear and testing setups.

All this so the panel has precise control and measurement, a must have for any laboratory doing triaxial or permeability.

Integration and Compatibility

The Master Control Panel is designed to work with other soil testing equipment, consolidation, shear and permeability. The panel is compact and expandable so it can be connected to additional cells and equipment for commercial laboratories. The panel is also compatible with other accessories, Digital Pore Pressure Supply Gauge and Specimen Height Indicator. So it can be adapted to any testing environment.

The de-airing tank allows for de-aired water preparation for sample saturation and testing, to make testing more efficient and precise.
