    摘要: Provided is a combine sensor including a pressure sensor module as a pressure detector, a thermistor unit as a temperature detector, a housing portion housing the temperature detector closer to a flow path than the pressure detector. The temperature detector includes a thermistor case where a first lead and a second lead connected to a thermistor are partially embedded. The thermistor case includes an extension part and a ring part including a flow hole part. The thermistor is supported by the extension part to be arranged outside an opening end. The extension part is provided by being separated into a portion where the first lead is embedded and a portion where the second lead is embedded, along an extending direction of the extension part, and includes a space portion communicating with the flow hole part and the outside.

    摘要: A sensor arrangement for measuring the pressure and temperature of a fluid includes a housing, a pressure sensor element, and a temperature sensor case. The housing includes a passage and a fluid opening, the passage and the fluid opening being in fluid communication. The pressure sensor element is connected to the housing, the pressure sensor element being in fluid communication with the passage. The temperature sensor case includes at least one temperature sensor element, the temperature sensor case being at least partially arranged in the passage. The sensor arrangement further includes an attachment element, wherein the attachment element attaches the temperature sensor case to the passage. The sensor arrangement further includes a fluid channel extending at least in part between the housing and the temperature sensor case, the fluid channel passing the attachment element and being in fluid communication with the fluid opening and the pressure sensor element.

    摘要: A pressure sensor configured to prevent tearing or cracking of an insulating film for insulating between a stem and a detection circuit from occurring. A stem having a planar outer bottom surface, an outer side surface intersecting the outer bottom surface, and a pressure receiving inner surface that is the opposite surface to the outer bottom surface and receives pressure from a fluid to be measured; and a detection circuit provided to the outer bottom surface with an insulating film interposed therebetween. The stem has a foot part that: is formed to surround the outer bottom surface; consists of a surface which, when observed parallel to the outer bottom surface, faces a direction different from the direction of the outer bottom surface and the outer side surface; and connects between the outer bottom surface and the outer side surface. The insulating film covers a portion of the foot part.
