摘要： A method for the compensating temperature gradient influences on a pressure measuring transducer, comprising the steps of: registering a pressure signal Sp(t); registering a temperature signal T(t); ascertaining a pressure measured value ps(Sp(t), T(t)); determining the time derivative of the temperature signal dT/dt; correcting the pressure measured value with a correction function, which depends on the time derivative, wherein, as a function of the sign of the time derivative, another correction function is selected, or other coefficients in a function of equal type are selected.

摘要： A method for operating a pressure sensor, which includes a measuring membrane, at least one platform and a capacitive transducer having two pressure dependent capacitances between electrodes on the measuring membrane. The measuring membrane divides a volume pressure-tightly into two volume portions, wherein the second volume portion is enclosed in a measuring chamber between the measuring membrane and the platform. A deflection of the measuring membrane depends on a pressure measurement variable p, which is a difference between a first pressure p1 and second pressure p2 in the volume portions. The pressure measurement variable p follows from both capacitances, wherein, for an intact pressure sensor, the second capacitance is a predetermined function of the first capacitance and, in given cases, the temperature. The method has steps as follows: registering value pairs of both capacitances; testing whether the value pairs correspond within a tolerance range to the predetermined function; and determining a change, respectively damage, of the sensor, when this is too long not the case.

摘要： A gauge pressure sensor for determining the pressure of a medium by means of a housing and by means of a measuring element, which is positioned in the housing, wherein an outwards facing side of the measuring element is in contact with the medium and is exposed to the pressure, which is to be measured. A tube for a reference pressure is provided, which conducts ambient air to the measuring element, and by means of at least one dehumidifying chamber, positioned in the housing, for the collection of air moisture. The dehumidifying chamber contains a moisture adsorbing material or is primarily composed of a moisture adsorbing material, in that the moisture adsorbing material is at least, in sections, enclosed by a wall, which is composed of a first moisture permeable material, or is at least, in sections, free from a wall, and in that the reference pressure supply tube is at least, in sections, fabricated from a first or second moisture permeable material or in that the reference pressure supply tube has an aperture.
