Technical Specifications
The Hydromatic is used to generate water pressure in and around the test specimen. The unit consists of a hydraulic piston, driven by a ball-screw and gearbox, mounted on a ball-slide, and works accurately under closed-loop control. It is driven by a high precision stepper motor, which enables the volume change measurement.
Four models are available depending on:
Number of pressure lines: one or two.
Max. pressure capacity: 3500 kPa or 1700 kPa
For a standard effective stress system, one Double line Hydromatic units is required - one line is used for the cell pressure and the other for the back pressure.
All the Hydromatic models also include the ON/OFF solenoid valve(s) which shall be fitted on the triaxial cell for opening and closing the line.
The status of the unit is continuously monitored by the software and safety switches prevent the over-travel and/or over capacity. A typical use of a single line Hydromatic is as additional line for permeability test in triaxial cell. Pressure transducer and de airing block are included.
Main Features:
Powers up to two hydraulic pressure lines and measures both the associated volume changes
High volume capacity 250 cc
Easily installed vertically or horizontally
Measure pressure and volume change with high-resolution, respectively 0.1 kPa and 0.001 cc
Four models are available depending on: max pressure capacity (3500 or 1700 kPa) and number of pressure lines (one or two)
Generates water pressure regulated under closed-loop control up to 3500 kPa or 1700 kPa
No air compressor required.
