Pressure and volume controller for triaxial tests - AUTOTRIAX EmS

The Hydromatic is used to generate water pressure in and around the test specimen. It is driven by a high precision stepper motor, which enables the volume change measurement. 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.
Four models are available depending on:
·         Max. pressure capacity: 3500 kPa or 1700 kPa
·         Number of pressure lines: one or two.
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.
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. The status of the unit is continuously monitored by the AUTOTRIAX EmS software and safety switches prevent the over-travel and/or over capacity.
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.
