A housing assembly for receiving at least one sensor for measuring parameters of a fluid has an outer housing with a connection for connecting the housing arrangement to a container containing the fluid. An inner housing is arranged in the outer housing, is suitable for receiving the sensor and is connected to a tube. The tube is connected to the outer housing at the connection and is adapted to direct the fluid into the inner housing. The housing assembly also has a heating device in or on the inner housing which is suitable for heating the inner housing to a predetermined temperature and maintaining it at this temperature. The inner housing and the outer housing are spaced apart from each other except at the junction of the connection and supply pipe and the space formed thereby is evacuated.

A strain inducing body includes a strain inducing portion including a movable portion that deforms in response to force or moment in a predetermined axial direction and a non-movable portion that does not deform in response to the force or moment, and an input transmitter that is connected to the non-movable portion and does not deform in response to the force or moment, wherein the input transmitter includes, a first frame portion, a plurality of first beam structures each of which has one end thereof connected to the first frame portion and extends from the first frame portion to an inside of the first frame portion, a first coupling portion that connects other ends of the first beam structures, an accommodating portion that is provided inside the first coupling portion and that is capable of housing a sensor chip to detect the force or the moment.

A capacitive diaphragm gauge (CDG) is positioned in a pressure sensing section of a pressure measuring unit. The CDG is heated to maintain the CDG at a temperature selected to reduce contamination build-up on the diaphragm of the CDG. The pressure sensing section is connected to a first mounting interface of a thermal barrier. A second mounting interface of the thermal barrier is connected to an electronics section. The thermal barrier includes a plurality of struts that mechanically interconnect the first mounting interface to the second mounting interface. The struts have sizes selected to be sufficiently large to cantilever the electronics section from the sensing section. The sizes of the struts are selected to be sufficiently small to reduce the heat transfer from the first mounting interface to the second mounting interface to maintain the second mounting interface below a selected maximum temperature.

The invention relates to a method for producing a sensor housing for a pressure sensor and to a sensor housing for a pressure sensor, to a pressure sensor having such a sensor housing, and to the use of an additive production device for producing such a sensor housing. A sensor body and/or at least one membrane stamp is applied to a provided metal plate by means of additive production. The additive production produces an integrally joined, in particular planar joint connection between the sensor body and/or the at least one membrane stamp, on the one side, and the metal plate, on the other side.

The aim of the invention is to economically produce a pressure measuring sensor element, and relates, according to one aspect, to a method for producing a pressure sensor measuring element for a pressure sensor which comprises at least one membrane and a covering protecting the membrane, the pressure sensor element being produced in a layer-by-layer generative production method. This makes it possible to, for example, easily construct a combination sensor for detecting pressure and an additional parameter. It is also possible to structures for reinforcement or for influencing resonant frequency or for influencing heat conduction.

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 housing having a tubular shape, and including a front end including an opening; a diaphragm that is disposed to close the opening, and is structured to deform depending on a pressure exerted on a front side of the diaphragm, and includes a hole extending rearwardly from a front end face of the diaphragm; a sensor element structured to output a signal varying depending on an amount of the deformation of the diaphragm; and a heat receiver including a first portion and a second portion. The first portion is disposed in the hole of the diaphragm, and is joined with an inner periphery of the diaphragm defining the hole. The second portion is formed integrally with the first portion, and is disposed adjacent to a front end of the first portion, and is structured to cover the front end face of the diaphragm.
