Description
The PLC controls the proportional valves for preloading, clamping and regulating the clamping force during vibration measurement. The pressure accumulators ensure that the clamping forces remain stable for up to 20 minutes in experimental measurements without pump operation. With PLC-controlled hydraulics, clamping forces of up to 650kN are possible.
