Abstract: Exemplary embodiments of the present invention relate methods and devices for measuring flow rate of particulate matter within an exhaust gas stream. In one particular exemplary embodiment, a sensor for detecting and monitoring particulate matter within an exhaust flow path of an engine is provided. The sensor includes a housing having an attachment for mounting the sensor. The sensor also includes a sensing rod supported by an insulating base. The sensing rod is attached to the housing and includes a probe adapted to be placed within the exhaust flow path. The probe includes a section having an increased surface area per unit length as compared to at least one other section of the probe. The sensing rod is configured to detect particulate matter flowing through the exhaust component and generates a signal based thereupon. The sensor further includes an electrical connector in communication with the sensing rod. The electrical connector is configured to transmit the signal generated by the sensing rod to a controller.

Abstract: A pressure detection mechanism having a pressure sense die which may be attached directly to a surface of an alumina-based substrate with an adhesive having an optimum thickness. The adhesive may be stress compliant and may be one or more of silicone, silicone-epoxy, epoxy or any other suitable adhesive material. A compensation and interface application specific integrated circuit may be attached to the surface of the package substrate. The pressure sense die may be electrically connected to the integrated circuit with bond wires. The integrated circuit may be electrically connected to trace conductors on the package substrate with bond wires, and trace conductors may be connected to stress compliant metal conductors or leads for external connection to a mounting surface such as a printed circuit board. Hard plastic, or like material, symmetric covers, with one or more pressure ports or vents, may be attached to both sides of the substrate.

Abstract: The present disclosure relates to pressure sensors. In one illustrative embodiment, the pressure sensor may include a pressure sensor assembly having pressure ports on opposite sides of the pressure sensor assembly. The pressure sensor may include a protective housing including a first housing member and a second housing member defining a cavity for securely housing the pressure sensor assembly. The protective housing may include a first port coupled to one of the pressure ports of the pressure sensor assembly and a second port coupled to the other pressure port of the pressure sensor assembly. In some cases, the protective housing may include one or more aligning features, one or more positioning features, and a boss, which can include two or more bumps, on each side of the cavity around the pressure ports.
