Manual Control Panel
Supports the following standards: ASTM D7181, ASTM D4767
For those operations, which do not require automated control, Humboldt's HM-4164 and HM-4165 Manual Triaxial Control Panels provide an accurate and easy-to-operate solution for controlling compressed air, water, deaired water and vacuum within an air/water bladder-type triaxial testing system.
The use of these Control Panels provides the necessary control for making changes in cell and back pressures required for sample saturation to be done from a central location on the panel. The operator has complete control of system pressure during the triaxial test with three independently-controlled pressure regulators.
These control panels have a bias pressure regulator feature, which allows simultaneous control of confining and back pressures, while maintaining a constant differential pressure.
Humboldt Manual Control Panels feature an analog input pressure gauge and controller, an air/water filter for the input pressure and de-aired water tank input, a digital pressure readout for each set of cell functions, as well as quick-disconnects for quickly connecting bladders, the pressure controller and triaxial cells.
Specifications
The HM-4164 provides connections for one triaxial cell, while the HM-4165 provides connections for up to three triaxial cells. For each triaxial cell, one bladder is required for generating the cell pressure and a second bladder is required for back pressure.
