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.

Packaging multiple measurands into a combinational sensor system using elastomeric seals

A modular sensor system includes a plurality of varying types of sensors that provide multiple sensing measurands for sensing operations. A housing is generally associated with the varying types of sensors, such that the housing introduces media to be sensed by the sensors. An electrical interface can also be connected to the sensors, wherein the electrical interface permits a logical physical connection to be made to a selected sensor in order to maximize sensing sensitivity and provide a sensing repeatability and accurate sensor compensation thereof for the sensing operations.

Combi-sensor for measuring multiple measurands in a common package

A system for sensing or measuring the motion of a fluid such as air. The system typically has a two-part plastic body containing an internal flow passage. The parts of the body may snap together or attach with an adhesive. A transducer or an electronic sensor is typically located within the flow passage, which may measure mass flow rate and may have two resistive thermal devices (RTDs) located on either side of a heat source. The body may have two elongated port tubes configured to attach to tubing. The port tubes may contain venturis, and may be substantially straight and substantially parallel, forming a U shape. A metal lead frame may be provided in electrical communication with the sensor. The lead frame may be integrally molded within the body, and may have a lower coefficient of thermal expansion than the body. The internal flow passage and the sensor may be substantially symmetrical and measure the flow rate of the fluid substantially equally in either flow direction. The system may be configured for surface mounting or for through-hole mounting, and may be a dual in-line type.
