Fluid Power Actuators and Components

360 picture of the lab


In the Fluid Power Actuators and Components  Laboratory focus is on detailed testing of actuators and components besides in-house designed and built proto type components. This includes for examples performance tests of fast switching valves for digital fluid power applications but also detailed characterization of e.g. friction phenomena in cylinders and methods for non-invasive lubrication film thickness measurement in fluid power machinery.

The laboratory has a wide selection of standard instruments, sensors, and data acquisition systems but also highly specialized equipment is available. This includes e.g. a high-bandwidth laser-based distance measurement system with micrometer accuracy, an eight channel ultra sound pulser/receiver, high-bandwidth piezo-based high-pressure sensors, etc.
