  • Publication number: 20230393108
    Abstract: A sensor for detecting at least one property of a fluid medium in at least one measuring chamber. The sensor includes a sensor element having at least one heatable diaphragm and an electrical measuring bridge. The diaphragm is connected to the electrical measuring bridge. The sensor is furthermore designed to detect an electrical resistance of the measuring bridge. The sensor is designed to detect a pressure of the fluid medium based on the detected electrical resistance of the electrical measuring bridge.

  • Patent number: 9618471
    Abstract: A circuit system for measuring a sensor element capacitance of a sensor element, in particular of a capacitive humidity sensor, including: the sensor element, which has the sensor element capacitance; a charge storage element, which is connected directly, or only via a resistor element, in series to the sensor element; and a control unit, which is configured to charge the charge storage element to a reference voltage and to successively transfer the charge via the sensor element capacitance until the charge storage element has reached a particular comparison voltage, the sensor element number of transfer processes thus ascertained representing information about the sensor element capacitance of the sensor element.

  • Publication number: 20150369766
    Abstract: A sensor device includes a housing in which there is a measuring space, a humidity module at least partially disposed within the measuring space and that includes a humidity sensor element for sensing humidity of a fluid medium in the measuring space, and a first temperature sensor for sensing a temperature of the fluid medium in the measuring space, and an evaluation unit that performs a method of outputting a first temperature signal of the first temperature sensor that indicates the temperature of the fluid medium in the measuring space, correcting a humidity signal of the humidity sensor element using a second temperature signal, which indicates a temperature of the fluid medium in a region of the sensor device that is thermally decoupled from the evaluation unit, and outputting the corrected humidity signal indicating the humidity of the fluid medium in the measuring space.

  • Publication number: 20030181998
    Abstract: A device for reliably generating signals, which includes a control means (10) that is supplied a control signal (12). The control means (10) generates a trigger signal (13, 14) as a function of the control signal (12), in order to trigger a load (50). Emergency operating means (30, 32) are provided, which, in an emergency operation, generate the trigger signal (34, 14) as a function of the control signal (12).
