Abstract
A pneumatic drive and a method for acquiring the power of a pneumatic drive are specified. A piston is movably disposed in a working space and coupled to a path transducer. A pressure sensor is provided for acquiring an internal pressure of the working space. An evaluation unit of the pneumatic drive is adapted to process the value of a path distance of a movement of the piston acquired by the path transducer as well as a variation of the internal pressure in the working space acquired by the pressure sensor. The variation of the internal pressure is associated with the movement of the piston in the working space. Based on these values, a power of the pneumatic drive can be determined.
