A method for manufacturing a pressure sensor includes: preparing a stem which has a cylindrical shape with a bottom as a diaphragm; mounting a sensor chip on the diaphragm; preparing a conductive member, in which an internal connection region is integrated with an external connection region electrically connected to an external circuit by an outer frame; forming a first resin mold to couple the internal connection region to the external connection region; separating the outer frame from the internal connection region and the external connection region; arranging the internal connection region in the stem; and electrically connecting the sensor chip and the internal connection region through the first connection member.

A gas turbine engine includes a liner positioned within a compressor section or a turbine section of the gas turbine engine and at least partially defining a core air flowpath through the gas turbine engine. The gas turbine engine also includes a casing at least partially enclosing the liner. Additionally, the gas turbine engine includes a pressure sensor assembly having a body, an extension member, and a pressure sensor. The pressure sensor is positioned at least partially within the body and the body is positioned at least partially on an outer side of the casing, the extension member extending from the body through a casing opening in the casing and towards a liner opening in the liner. The extension member defines a continuous sense cavity exposing the pressure sensor to the core air flowpath.

A pressure sensor includes a connection portion provided with a screw portion configured to fix the pressure sensor to a combustion chamber of a vehicle engine; a hollow liquid-enclosing container fixed to one end of the connection portion; a pressure transmission fluid enclosed inside the liquid-enclosing container; a diaphragm fixed to one end of the liquid-enclosing container and elastically deformed when receiving pressure to transmit the pressure to the pressure transmission fluid; a pressure detection element fixed to the other end of the liquid-enclosing container and detecting the pressure transmitted to the pressure transmission fluid and converts the detected pressure into an electric signal; and a heat-dissipating rod provided inside the liquid-enclosing container. The connection portion and the liquid-enclosing container, and the connection portion and the diaphragm are mechanically connected to each other by welding or the like.
