摘要： A pressure measurement member includes an insulation bottom layer, a flexible insulation top layer and at least one spacer. The insulation bottom layer has a bottom conductive element on the surface thereof. The flexible insulation top layer has a top conductive element on the surface thereof adjacent to the insulation bottom layer and opposite to the bottom conductive element. The spacer is located between the insulation bottom layer and flexible insulation top layer to separate the insulation bottom layer and flexible insulation top layer. As different pressures could result in different impedance variations on the contact area between the top conductive element and bottom conductive element, the pressure being applied can be derived from the impedance variation. The invention can measure pressure without using piezoresistive material to reduce cost.

摘要： A pressure or force sensor has a sensor housing, a measuring element in the housing, and a sensor membrane. The membrane is delimited by an inner edge and an outer edge, which is connected in a pressure-resistant manner to the sensor housing. The inner edge transitions in a pressure-resistant manner into a movable plunger, the travel of which can be detected by the measuring element. The membrane has one or more elastic regions between the outer edge and the inner edge, each region having a thinnest point, wherein the material thickness inside the elastic region increases steadily on both sides of this thinnest point. The cross-section of the membrane has an arched shape in each elastic region, and the arched shape has a convex outer and concave inner contour relative to the arch orientation.

摘要： A pressure sensor comprises a sensor platform; a measuring membrane, or diaphragm, which is held by the sensor platform, and can have a pressure applied to it and is deformable as a function of pressure; and at least two resistance elements having an AlxGa1—xN layer. At least a first resistance element of the at least two resistance elements is arranged on the measuring membrane, or diaphragm and has a deformation-dependent resistance value. The pressure sensor can be operated using a measurement circuit to register a signal which depends on the resistance values of the at least two resistance elements in the plane of the AlxGa1—xN layer. Four resistance elements are preferably provided in a full bridge.

摘要： A sensor preferably capable of high resolution sensing over a large operating range includes a composite diaphragm containing nanotubes or nanowires. The nanotubes or nanowires preferably form a mat that is embedded in insulating material, such as high dielectric or insulating thin films. The nanotubes or nanowires may provide the diaphragm with a Young's modulus of greater than about 1000 GPa and a tensile strength of greater than about 100 GPa. The strain in the nanotubes or nanowires may be measured by a change in resistance, voltage, current or capacitance.

摘要： In a resistively heated heat-loss pressure gauge, electrical current is switched between a sensing element and a compensating element at different duty cycles. As a result, the sensing element is heated relative to the compensating element. A fixed resistance is placed in series with at least the compensating element. The current source applies current to heat the sensing element to a temperature at which the resistance of the sensing element matches the combined resistance of the compensating element and the fixed resistive element.

摘要： A capacitive pressure transmitter is provided. In one aspect, the transmitter includes a capacitive pressure sensor coupled directly to the measured media without any intervening fluid isolation. A filter is preferably used to keep particulates from reaching the measuring diaphragm. In another aspect, a capacitive pressure transmitter is provided with at least one self-contained isolator interposed between a process connection and the capacitive pressure sensor. In both aspects, the capacitive pressure transmitter is relatively small and preferably constructed from materials that facilitate low-cost manufacture.

摘要： A pressure measurement device comprising an absolute pressure sensor and a bus coupling serial communication and energization to an electrical connector in a field wiring compartment. An atmospheric pressure sensor module is connected to the bus at the electrical connector. The bus provides the energization to the atmospheric pressure sensor module and the bus receives a serial communication signal from the atmospheric pressure sensor module. The serial communication signal includes numeric data representing atmospheric pressure. The pressure measurement device provides a gage pressure output as a calculated difference between the sensed absolute pressure and the received numeric data.
