EPSC - 2-channel controller
EPSC - 2-channel controllerEPSC - 2-channel controller
2-channel controller for pneumatic and electromechanical devices for: retrofitting / conversion of shear testers, construction of permeability testing systems and triaxial systems
The universal 2-channel controller of type EPSC can be used wherever very precise pneumatic pressures must be set and controlled in one drive and very precise electromechanical speeds and forces in a second drive. This makes this controller particularly suitable for retrofitting or converting shearing devices with pneumatic load generation and electromechanical shear axis.
- electro-pneumatic pressure regulator for laboratory use with a maximum test force of 10kN
- electromechanical controller (e.g. control of shear force and shear rate) for laboratory use with a maximum test force of 10kN
- compact design, the actuators (valve system and motor control) are integrated in the device
- intuitive operation and easy handling with 4,3” touch screen with separate function keys and haptics
- High-speed controller system with bus coupling, control loop with 1 ms sampling time
- precise settlement or displacement measurement with digital dial gauge, resolution 10 µm and 1 µm
- automatic internal limitation of the pressure (the load and the press stroke depending on the application) or the shear force to protect the measuring sensors
- Manual operation for setting up the traverse or the pressure stamp (depending on the application)
- adaptable to the corresponding sample and test parameters by interchangeable force sensors and automatic detection of the measuring range
- detection of external sensors with voltage output 0 .. 10 V DC (e.g. pressure and temperature sensors)
- serial interface for automatic control and measurement data acquisition via PC and the GeoDESC software
available accessories:
- various force measuring systems (1 kN, 2 kN, 5 kN, 10 kN)
- digital displacement sensors from 12,5 mm to 60 mm measuring range, resolution 10 µm and 1 µm
- external sensors, e.g. pore pressure sensors for triaxial testing
