EPC.LSC - Compressed air controlEPC.LSC - Compressed air control
Automatic compressed air control with load and settlement control for: retrofitting consolidation stands (pneumatic oedometers), installation of permeability testing systems and triaxial systems
The EPC type automatic electropneumatic pressure control system can be used wherever very precise pneumatic pressures need to be set and controlled. A force signal, displacement signal, or settlement signal can be integrated as the control variable. This makes this pressure control system particularly suitable for expanding or converting pneumatic loading devices, such as consolidation stands, load settlement devices, or oedometers.
- compact design, actuators (valve system) 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 measurement with digital dial gauge, resolution 10 µm and 1 µm
- Automatic internal pressure limitation (load and press stroke depending on the application) to protect the 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
- measurement of a external analog signal 0 .. 10 VDC (e.g. pore pressure sensor and temperature sensors)
- serial interface for automatic control and measurement data acquisition via PC and the GeoDESC software
- 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
