摘要： Disclosed is method of manufacturing a pressure sensor for measuring a fluid pressure in a device. The pressure sensor comprises a port element with a sealing structure and a membrane. Four strain gages will be attached to the membrane. The gages are used in a Wheatstone bridge to sense the fluid pressure. A first finite element action determines a first contour (C1) around the membrane central axis with equal compressive strain and a second contour (C2) around the membrane central axis with equal tensile strain wherein when fluid pressure is applied to the membrane strain on the first contour is opposite strain on the second contour. A second finite element action determines the four positions of the strain gages on the first and second contour such that the difference between the highest error signal and the lowest error signal at the output of the Wheatstone bridge is minimal under influence of parasitic forces acting on the pressure sensor.

摘要： [Objective] To provide a glow plug with a combustion pressure sensor which senses combustion pressure on the basis of an axial movement of a ceramic heater and in which deterioration in the combustion pressure sensing performance is prevented as a result of prevention of impairment in easiness of deformation of a displacement member and easiness of displacement of the heater, which could otherwise result from adhesion and accumulation of soot on the displacement member, etc., the displacement member axially blocking a space between the inner circumferential surface of a forward end portion of the housing and the outer circumferential surface of the ceramic heater.
[Means for Solution] A heater 200 has a rear heat-generating element 260 formed of a resistance heat-generating element, adapted to generate heat through application of electricity, and provided in an axial region thereof between a forward end 136 of a housing and a rear end 315 of a displacement member 300 located rearward of the forward end 136, separately from a forward heat-generating element 205 provided at a forward end portion of the heater for accelerating ignition. Since the rear heat-generating element 260 removes the above-mentioned soot through burning, impairment in easiness of deformation of the displacement member 300 and easiness of displacement of the heater can be prevented accordingly, thereby preventing deterioration in sensing accuracy.

摘要： The invention relates to a high temperature pressure sensor element (10; 20), in particular for jet engines, comprising a substrate (11) with an inner region (12) configured therein, a defomable membrane (13) which separates the inner region (12) from the outer region and deforms during operation in the event of a change of pressure, and a strain gauge element (14a, 14b, 14c) disposed on the membrane (13) for measuring the deformation of said membrane (13). The substrate (11), the membrane (13) and the strain gauge element (14a, 14b, 14c) are all made of the same high temperature stable material, particularly an alloy, such as a nickel-based alloy. A component for a jet engine, such as for example a turbine blade for an aircraft or a rocket engine, comprises such an integrated high temperature pressure sensor element (10; 20).
