FAQ

Description

The PLC controls the proportional valves for pre-clamping, clamping and regulating the clamping force during the vibration measurement. With PLC-controlled hydraulics, clamping forces of up to 650kN are possible. The accumulators ensure that, during experimental measurements—including those lasting longer than 20min—the clamping forces remain stable.
