A sash position sensing system for a fume hood (10) and the like having a plurality of movable sashes (12a, 12b, 12c, 12d) in a frame includes an indicator element (24) affixed to each sash and an array (20) of sensor elements (22) extending along the frame. The sensor elements interact with the indicator elements when generally aligned therewith. The status of the sensor elements is captured in parallel without the need for multiplexing the sensor array, and a processor (52) reads the captured state information and calculates the open area of the frame. In further aspects, a method for determining the position of one or movable sashes in a frame and a fume hood employing the sash position sensing system of the present invention are also provided.
