Descripción

These are the brains of the AUTOTRIAX EmS system, transmitting data and information between the software and all the active components such as the pressure controllers and Tritech triaxial load frame. The units are produced in four different versions (see below) to offer maximum flexibility.  They can be stacked vertically, making them very space-efficient, and power connectors of multiple units can be daisy-chained together, allowing them all to be run from a single mains socket.  Transducer calibrations are saved directly in the firmware of the units.


Master unit 

Master unit is always required, whatever combination of systems you want to put together. It has four active control channels for connecting the transducers that are needed for feedback to the software (for controlling vertical load or displacement and cell and back pressure) and eight passive channels for connecting a pore pressure transducer plus any other additional transducers, including local measuring on-sample.  The Tritech compression frame, Hydromatic pressure/volume controllers and solenoid valves (for opening and closing the pressure lines) also connect to the unit.
One Master unit is all that is needed for a single standard effective stress system.
Connections:
- 2 Hydromatic pressure/volume controllers
- 1 Tritech compression frame
- 12 transducers
- 2 solenoid valves

Pressure extension unit 

Used in addition to a Master unit, this expansion unit provides control for one extra pressure system, with connections for a pressure transducer, Solenoid valve and Hydromatic pressure/volume controller, plus three spare passive transducer channels.  It could be used, for example, in a system running permeability tests where three controlled pressures are required.
Connections:
- 1 Hydromatic pressure/volume controller
- 4 transducers
- 1 solenoid valve


Triple pressure extension unit

Used in addition to a Master unit, this expansion unit provides control for three extra pressure systems, with connections for three pressure transducers, Solenoid valves and Hydromatic pressure/volume controllers, plus nine spare passive transducer channels. 
Connections:
- 3 Hydromatic pressure/volume controllers
- 12 transducers
- 3 solenoid valves


Pressure extension unit  for unsaturated test module only

Used in addition to a Master unit, this expansion unit provides control for one air pressure system, with connections for a pressure transducer, Solenoid valve and Servoflow 2 Air pressure controller.  There is also a connection for an Automatic Volume Change device to measure the change in cell volume, plus two spare passive transducer channels. 
Connections:
- 1 Servoflow
- 4 transducers
- 1 solenoid valve
- 1 Automatic Volume Change device
