Abstract: In a two-conductor technology circuit the use of certain ASIC components is made possible which, for instance, allow for the supply of contact-free rotational angle sensors, although said ASIC components have a high current consumption.

Abstract: The invention relates to a pressure gauge having a cylindrical housing to which a bushing is fixed, which penetrates the housing. The pressure gauge is furthermore provided with a pressure sensor together with an allocated electronic evaluation unit, said sensor is operatively connected to a pressure port coaxially positioned to the longitudinal axis of the housing. A turnable adjustment pin to engage with an adjustment device of the electronic evaluation unit in the pressure gauge is accommodated in the bushing in a liquid-proof manner, and is equipped with holding means by means of which it is undetachably secured to the bushing.

Abstract: A sensor assembly consists of a metallic pressure sensor cap welded to a tubular gland, which integrally forms a sealing edge on its one end opposing the pressure sensor cap side, a housing part, which has an opening formed therein such that the gland can penetrate the same, and a gland nut being turnably supported on a projecting portion of the gland for attaching the sealing edge to a process port. A stepped portion of the sensor cap is welded to a stepped portion of the gland, and the housing part is fixed to the outside surface of the gland in a position between the sensor cap and the sealing edge. Here, the sensor cap has an outer diameter, which is smaller than or equal to an outer diameter of the gland, so that the sensor cap being welded to the gland beforehand can be fitted into the opening of the housing part.

Abstract: An absolute pressure transducer for outputting a signal indicative of an absolute pressure of a process to be measured is provided. The pressure transducer consists of a pressure-tight pressure port, which is connectable to the process, a housing accommodating pressure sensors and a common circuit board, a first pressure sensor, which analogically detects a difference between the process pressure and an ambient pressure inside the housing, a second pressure sensor, which detects the ambient pressure inside the housing as an absolute pressure, and the common circuit board, which is connected to both the first pressure sensor and the second pressure sensor and furthermore has a data processing unit. Here, the second pressure sensor is adapted to issue an electronic signal indicative of the ambient pressure.

Abstract: In a method for converting an analogue measurement indication into electric signals, the angle of rotation of the pointer of an analogue display is contact free detected and converted into a proportional electrical output signal. This is achieved by using an application-specific integrated circuit having a Hall sensor which can detect the magnetic flux density parallel to the surface of the integrated circuit.

Abstract: The bimetal thermometer according to the invention comprises a bimetal helix arranged inside a protective tube, one end thereof being attached to the protective tube and the other end thereof being connected to a pointer shaft to which a pointer arranged inside a casing is attached. The pointer shaft is rotatably journaled in a bearing assembly in which a cavity is formed through which the pointer shaft extends. The cavity is filled with semisolid lubricating grease for damping vibration movements of the pointer shaft. The pointer shaft has either a smooth surface or is provided with at least one radial projection arranged inside the cavity. Vibration movements of the pointer shaft are damped by the interaction of the pointer shaft and, if provided, the projections with the viscous lubricating grease.

Abstract: The invention relates to a pressure sensor comprising a sensor element (2) having a flat membrane (4) which is transformed at its edge into a hollow-cylindrical ring (6) so that a central recess (20) is provided at the lower side (10) of the membrane (4). On the upper side (8) of the membrane (4) a resistance arrangement consisting of electric resistors is disposed. A sleeve (54) projects into the recess (20) and supports a first elastomeric sealing ring (66) which is tightly arranged at the circumferential area of the recess (20). Furthermore the sleeve (54) supports a second elastomeric sealing ring (68) which serves for sealing at a feeding tube for pressure fluid formed in a component part to which the pressure sensor is mountable. The sleeve (54) is rigidly connected to a disk (56) which is attached with its outer edge (58) to a casing (26) enclosing the sensor element (2).
