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 transmitter has a pressure sensor, an isolator diaphragm, and a fill tube. Interior passages in the pressure sensor module body are filled with isolator fluid and provide fluid connections. The isolator fluid couples pressure from the first isolator diaphragm assembly to the pressure sensor.
