ABSTRACT:
A measuring device connectable to a pressure conduit of a hydraulic circuit for determining characteristic operational parameters of hydraulic energy converters forming components of the hydraulic circuit includes a measuring section having a conduit guiding pressurized fluid of the pressure conduit and a throttle in the conduit for effecting a pressure drop thereacross; a differential pressure transducer communicating with the conduit at an upstream side and a downstream side of the throttle as viewed in a direction of fluid flow for determining a pressure differential across the throttle and for generating an output signal representing the pressure differential; and an electrotransducer connected to an output of the differential pressure transducer for separating the output signal into an alternating voltage component signal and a direct voltage component signal. The electrotransducer has an output to which the alternating voltage component signal and the direct voltage component signal are applied.
