Abstract (en)
[origin: WO2010136131A1] The invention relates to a position measuring device for capturing the position of at least one actuator (19) of a fluidic system (10) without a position sensor arrangement, wherein at least one fluidic control valve (12) is provided for controlling the fluidic system (10). A volume flow and pressure sensor device (17) is connected in an infeed line (13) to the fluidic system (10) and directly connected to a controller (18). The controller (18) has means for calculating the position x of the actuator (19) according to the relationship (I).
