RTC - Real Time Control Box

The base RTC (Real Time Control) system is made up a chassis fitted with one module. This will control one fully automated triaxial test system. The RTC chassis can be fully expanded by installing two additional modules to allow control of three fully automated triaxial test systems. One RTC module can control:

• two pressure lines up to 3500 kPa
• two ON/OFF valves for drainage lines
• the speed of the Triaxia! load frame
• the flow direction of the automatic volume change

The base RTC system comes with RTC software which manages the transducers calibration and the setup of up to three systems. The calibration data can be exported to the supplied calibration spreadsheet template to print calibration certificates.

The RTC module, ATD data logger and computer running the software modules are all connected together by a high speed communications and control network which allows simultaneous communication between the RTC modules, ATD data logger and computer. When the RTC module receives a command from the test software, (e.g. a pressure increase, closing the pressure line to the triaxial cell, changing the triaxial load frame speed or changing the automatic volume change device flow direction), the commands are then applied to the triaxial system by a closed loop control system using feedback from the ATD data logger. The RTC module then runs independently of the test software maintaining all the current parameters until new commands are sent from the test software.

Note
Upgrading existing standard triaxial systems:
The advantage of the RTC system is that existing manual triaxial compression frames can be used as part of a semi-automated system. When you require the full automation you will need to upgrade to a Tritech triaxial load frame 29-WF4005 and/or vacuum cap assembly.

29-WF4530  RTC Base System
110-240V, 50-60 H2, 1 ph.
Base unit used to control one automatic triaxial system.

29-WF4531  RTC expansion module for two pressure outputs
This module added to the base system 29-WF4530 or to the 29-WF4537 controls two more pressure outputs and the relevant
accessories to measure the volume change.
The base system RTC can accept up to three 29-WF4531 modules to be used for permeability or unsaturated tests.

29-WF4537 RTC extension module
This module added to the base system controls another fully automated triaxial test system. A maximum of two RTC expansion modules can be installed for a 3 triaxial system control.
