An interface pressure sensor includes a fluid pressure sensor disposed in a volume defined by a shear wall. The volume is enclosed, and the fluid pressure sensor is encapsulated by, an infill material. The infill material defines a sensing surface that, when pressed, can impart a force that is detectable by the fluid pressure sensor.

Provided is a pressure detection device including a pressure detection unit and a channel unit. The channel unit has a contact part arranged in contact with the pressure detection unit, the contact part has a protective film arranged in contact with a pressure detection surface and configured to block contact between the pressure detection surface and a liquid and a body forming an opening arranged at an end of the channel, the protective film and the body are formed of a thermoplastic fluorine resin, and the protective film is arranged so as to close the opening of the body and welded to the body in an annular region extending circumferentially about the axis.

A sensor device for measuring a physical quantity. The sensor device includes a sensor element having a semiconductor chip, a first terminal electrically connected to the sensor element, and a housing portion having a terminal, which is a second terminal and is electrically connected to the first terminal. The second terminal has a through-hole formed therein, the through-hole having a first end and a second end opposite to each other, an inner surface of the through hole at the first end being an R-surface that is a curved surface with a radius R. The first terminal is housed in the housing portion, and has one end thereof inserted in the through-hole from the first end of the through-hole.

A sensor assembly includes: a sensor module including a cylindrical portion into which a measurement target fluid is introduced and a diaphragm including a first surface in contact with the measurement target fluid and a second surface provided with a detector; a joint provided with a pressure introduction port for introducing the measurement target fluid to the sensor module; a cylindrical base member surrounding the sensor module; an electronic circuit attached to the base member to receive a detection signal outputted by the detector; and a temperature sensor electrically connected with the electronic circuit.

A differential pressure sensor with wireless RFID communication ability senses and records a specified differential pressure threshold without great energy consumption and without requiring direct access or visual inspection of the sensing element. The differential pressure sensor includes a sensing element sensing a differential pressure between a low pressure side and a high pressure side and a RFID tag comprising a tag antenna, a tag integrated circuit (IC) and a tamper loop connected to the tag IC for tracking a specific differential pressure threshold of the differential pressure sensor. The RFID tag is connected to the sensing element in such a way that the tamper loop is triggered if the specific differential pressure threshold has been reached.
