Abstract
A combinational sensor system for measuring multiple measurands includes a flow transducer, a pressure transducer and a humidity transducer. The pressure and humidity transducers are provided with independent access to sensed media and are ratiometric to a supply voltage, whereas the flow sensor is sensitive to openings to the flow path. The combinational sensor system utilizes elastomeric seals that include patterned electrically conductive and non-conductive seals. An ASIC is generally associated with the combinational sensor, and is located on a patterned electrically conductive substrate lead frame or for signal conditioning in order to detect any of the sensed measurands. The transducers can be arranged in a manner that distributes the transducers to optimize the accuracy and response time of the combinational sensor system.
