摘要： A glow plug including a pressure sensor (830) and a heater (150). The glow plug includes a position-defining member which defines the positional relationship between the pressure sensor (830) and the heater (150) and has a coefficient of thermal expansion greater than that of the heater. The pressure sensor (830) is fixed at a predetermined sensor reference position relative to the position-defining member. The heater (150) is held by a heater-holding member (820) in such manner that an attachment position A of the heater-holding member to the heater can be displaced, with a change in external pressure, relative to a predetermined heater reference position defined by the position-defining member. A displacement transmission member (840) is arranged between the heater (150) and the pressure sensor (830) so as to transmit displacement of the heater (150) to the pressure sensor (830). The coefficient of thermal expansion of the displacement transmission member (840) is rendered greater than that of the position-defining member.

摘要： A glow plug with combustion pressure sensor is disclosed having a cover and a housing with which a piezoelectric element is hermetically accommodated. A lead wire having flexibility is employed to supply electric power to a heating member. The lead wire, fixedly connected to the heating member, extends through an insertion bore of the cover and is hermetically bonded to an inner circumferential wall of the insertion bore. When the heating member is axially displaced upon receipt of a combustion pressure, the lead wire flexes to absorb the resulting displacement, causing a joint portion between the cover and the lead wire to have no drag against the displacement. This allows the piezoelectric element to detect the combustion pressure with high precision.

摘要： A pressure-measuring device is to be placed in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmission element projecting out of the housing, and a pressure sensor disposed in an interior chamber of the housing. On the one hand, the pressure sensor is braced on a fixation element. On the other hand, to detect a pressure prevailing inside the chamber, the pressure sensor is operatively connected to the force-transmission element. The pressure sensor has a straight-through recess through which an electrical line is routed. In addition, a positioning element is provided, which has a straight-through recess in a guide region, the electrical line being routed through the straight-through recess, and the positioning element having a reduced thickness in the guide region. This makes it possible to reduce friction of the electrical line in the guide region at the straight-through recess, so that the pressure measurement is improved.

摘要： A piezoresistive pressure-measuring plug (100) for a combustion engine for measuring a pressure is disclosed. The piezoresistive pressure-measuring plug (100) comprises: a plug body (106, 108, 110) for insertion into a cylinder of the combustion engine, a rod (102) that is arranged in the plug body (106, 108, 110), a sensing structure (104) comprising a piezoresistive element, that is arranged between the rod (102) and the plug body (106, 108, 110) in such a way that the sensing structure is acted upon, in use, by the pressure prevailing in the combustion chamber of the cylinder, whereby the rod (102) transmits the pressure in the combustion chamber of the cylinder to the sensing structure due to the pressure in the combustion chamber leading to an axial motion of the rod (102) relative to the plug body (106, 108, 110) so as to apply a force to the sensing structure (104) and a PWB (114) provided with sensor electronics for measuring and conditioning a resistance change. The sensing structure (104) is arranged in the plug body (106, 108, 110) and, in use is compressed in axial direction by the force applied to the sensing structure (104) and a piezoresistive element (206) mounted on the sensing structure (104) to provide a resistance change when the sensing structure (104) is compressed in axial direction. Furthermore, the PWB (114) is arranged in the plug body (106, 108, 110). In this way a pressure-measuring plug is obtained with improved bandwidth and reduced build-in height.
