摘要： A transducer for determining a pressure of a hydrogen-containing fluid medium confined in a first space includes a pressure side end configured to be disposed facing the fluid medium. The transducer includes a housing, which defines a second space, and a measuring arrangement disposed in the second space. The pressure side end includes a diaphragm configured and disposed for hermetically separating the first space from the second space. The diaphragm includes a metallic material that is made of a high-alloy martensite.

摘要： A pressure sensor for measuring the pressure of a fluid medium includes a mounting device, a sensor device and a sealing element. The mounting device holds the sensor device and is mountable in a mounting bore of a wall. The sensor device includes a diaphragm and a sensor element, which generates a measurement signal for a pressure-dependent deformation of the diaphragm. The sealing element seals the mounting bore and includes a trunnion held by a socket of the sensor device.

摘要： A strain transmitter for detecting strain of a structure includes a strain body, which has a strain axis with fastening devices for fastening the strain body on a structure, and a measurement element, which is arranged centrally between the fastening devices on the strain axis. The measurement element includes a metal sheet. The entire surface of a statically measuring, piezo-resistant silicon chip, which is connected to a full bridge and emits a voltage in the strained state proportional to the level of strain, is applied to the metal sheet. The measurement element includes a printed circuit board, and electric contacts are guided from the silicon chip along the printed circuit board.

摘要： A joint joins an alloy member to a ceramic member via a glass joining agent, which is joined to the alloy member by a material bonded joint and to the ceramic member by a further material bonded joint. The glass joining agent is made of a glass having a melting point below 800° C.; a coefficient of thermal expansion of at least 9-10−6 K−1 and a bismuth content of at least 10%. The alloy member has a coefficient of thermal expansion of at least 9-10−6 K−1. The ceramic member has a maximum coefficient of thermal expansion of 8-10−6 K−1. The material bonded joint defines a mixing region that is a partial region of the ceramic member, and the bismuth content in the mixing region is higher than that of the ceramic member outside the mixing region.
