摘要： A high-precision pressure sensor, having a first base body that has two electrically conductive layers and an insulation layer arranged between the two layers and electrically insulating the two layers from one another, an electrically conductive measurement membrane arranged on the first base body with inclusion of a pressure chamber, which measurement membrane can be charged with a pressure to be measured, and an electrode provided in the membrane-facing layer and spaced apart from the measurement membrane, which electrode together with the measurement membrane forms a capacitor having a capacitance that varies according to the pressure acting upon the measurement membrane. The first base body is characterized in that it has a measurement membrane terminal via which a reference potential can be applied to the measurement membrane, an electrode terminal via which an electrode potential of the electrode can be tapped, and a shield terminal via which a shield potential that can be predetermined independently of the reference potential especially, a shield potential corresponding to the electrode potential can be applied to the layer facing away from the membrane.

摘要： The invention relates to a measurement transducer (1) comprising a sensor module (10), having a sensor (11) and sensor electronics (12), wherein the sensor (11) emits sensor signals, and wherein the sensor electronics processes the digitized sensor signals with a transmission function and provides processed sensor measurement values on a digital interface. The measurement transducer further comprises a main electronics module (20), which is functionally connected to the sensor electronics and a logic unit (22), and a communications interface (36), wherein the logic unit (22) is configured to receive the sensor measurement values provided on the digital interface and to cause the output of a measurement signal corresponding to the sensor measurement values through the communications interface (36). To this end, the logic unit is configured to carry out a monitoring function—wherein the monitoring comprises, in addition to a currently provided sensor measurement value, the reception of the associated digitized sensor signals, with the aid of a test function which comprises the transmission function—to calculate a control measurement value with the aid of the received associated digitized sensor signals, to carry out a comparison between the control measurement value and the sensor measurement value, and to cause the communications interface to emit an error signal in the event of deviations. The logic unit is also configured to provide the control measurement value to the sensor electronics (12), wherein the sensor electronics (12) are configured to carry out a comparison between the control measurement value and the sensor measurement value and to cause the communications interface (36), via an alarm output (18), to directly emit an error signal in the event of deviations.

摘要： A pressure transducer comprising a resistive pressure sensor element with a measurement membrane which has at least four resistor elements. The resistor elements are arranged in a full-bridge circuit, having a longitudinal direction in which the full bridge circuit is to be supplied with a constant current. When being supplied with the constant current, a longitudinal voltage has a first pressure dependency and a first temperature dependency, and a diagonal voltage has a second pressure dependency and a second temperature dependency, the second pressure dependency being greater than the first pressure dependency at a given temperature. The pressure transducer has a processing circuit which is designed to determine a measured pressure value at least using the diagonal voltage and optionally the longitudinal voltage. The processing circuit is further designed to check whether a value pair of a longitudinal voltage and a diagonal voltage corresponds to an expected functional relationship at a current temperature.
