Abstract
A pressure sensor for recording a pressure of a fluid medium in a measuring cell. The pressure sensor includes a sensor housing, at least one first pressure sensor element for measuring a pressure of the medium, and a drive and/or evaluation circuit for outputting a signal indicative of a pressure acting on the first pressure sensor element. The drive and/or evaluation circuit is configured on or in a circuit substrate disposed within the sensor housing. The first pressure sensor element is configured on or in the circuit substrate and is separated from the fluid medium by at least one first separating membrane.
Claims7
A pressure sensor for recording a pressure of a fluid medium, comprising:
- a sensor housing;
- at least one first pressure sensor element for measuring a pressure of the medium;
- and
- at least one of a drive and evaluation circuit, the at least one of the drive and evaluation circuit for outputting a signal indicative of a pressure acting on the first pressure sensor element, the at least one of the drive and evaluation circuit being configured on or in a circuit substrate disposed within the sensor housing;
