摘要:
A capacitive fill level sensor for determining a fill level of a liquid is described. Two electrodes are provided having a plastic sheathing and a capacitance measuring device for detecting the electrical capacitance between the electrodes. An estimator device is used for estimating a fill level of a liquid between the electrodes based on the detected electrical capacitance, taking into account different dielectric constants for sections of the plastic sheathing in the liquid and outside of the liquid.
摘要:
A sensor module having a heating structure and a sensor element is described. The heating structure surrounds the sensor element so that heat dissipation through a frame is largely prevented. This yields a greater measuring accuracy of the sensor module. In particular, interfering influences due to a temperature dissipation through the mount frame are thereby prevented.

The invention relates to a method to regulate a circulating air and/or intake air portion (Vs, Vo) in a passenger compartment of a vehicle, in particular a motor vehicle, with a sensor for detecting hazardous gas concentrations in the passenger compartment and for supplying a triggering signal (1CO2) of a control unit for the circulating air and/or intake air portion (Vs, Vo) in a passenger compartment. To achieve air supply in a passenger compartment that does justice to demand and is optimized with respect to energy consumption, the sensor for detecting hazardous gas concentrations is a temperature-compensated sensor, whereby the sensor for detecting the ambient temperature along with the sensor for detecting the hazardous gas concentration supply signals (1t, 1CO2) for triggering a control unit for the circulating air and/or intake air portion (Vs, Vo). The control unit controls either the size of the circulating air portion (Vs) in the passenger compartment or switches from complete circulating air operation to complete intake air cooperation and vice versa.
