摘要： A pressure measuring cell includes an elastic measuring membrane which is contactable with a first pressure on a first side and with a second pressure on a second side facing away from the first side. The measuring membrane is deflectable as a function of a difference between the first pressure and the second pressure, wherein the measuring membrane pressure-tightly isolates a first volume, which is facing the first side of the measuring membrane, from a second volume, which is facing the second side of the measuring membrane. The pressure measuring cell further includes a transducer for transducing the pressure dependent deflection of the measuring membrane into an electrical or optical signal. The measuring membrane has in the equilibrium state of the measuring membrane compressive stresses at least at the surface of the measuring membrane at least in a radial edge region, in which in the deflected state of the measuring membrane under pressure loading tensile stress maxima occur.

摘要： A pressure sensor having a diaphragm having a boss with a pattern. The diaphragm having a boss may be regarded as a bossed diaphragm. The bossed diaphragm may have higher sensitivity than a flat plate diaphragm having the same area as the bossed diaphragm. The bossed diaphragm may incorporate a simple cross pattern that can further improve the sensitivity and linearity of a pressure response of the diaphragm at low pressures. Reduction of sharp edges and corners of the boss and its legs around the periphery of the diaphragm may reduce high stress points and thus increase the burst pressure rating of the bossed diaphragm.

摘要： A capacitive pressure sensor includes a stator which encircles a portion of a cylindrical diaphragm. This encircling forms a circumferential gap between the sidewalls of the stator and the diaphragm. Therefore, a greater area “A” can be achieved in smaller diameter sensor footprint than prior art designs and yet still detect relatively small changes in capacitance. Additionally, the width “g1” of the gap can be wider than prior art designs without negatively affecting capacitance detection. A bonding agent which has a melting temperature of about half that of bonding agents used in prior art designs, secures the stator to the diaphragm and reduces oxidation issues during assembly, thereby decreasing manufacturing time and cost. To ensure proper side-to-side alignment of the stator relative to the diaphragm, a centering sleeve, which is removed after bonding, is placed over as stub at the upper end of the diaphragm.
摘要翻译：电容式压力传感器包括环绕圆柱形隔膜的一部分的定子。这种环绕在定子的侧壁和隔膜之间形成圆周间隙。因此，与现有技术的设计相比，在较小直径的传感器覆盖区域可以实现更大的面积“A”，并且仍然检测相对小的电容变化。此外，间隙的宽度“g1”可以比现有技术的设计宽，而不会不利地影响电容检测。熔融温度约为现有技术设计中使用的粘合剂的一半的粘合剂，将定子固定在膜片上，减少组装过程中的氧化问题，从而减少制造时间和成本。为了确保定子相对于隔膜的正确的侧向对准，在接合之后被移除的定心套被放置在隔膜的上端作为短截线。
