摘要： PROBLEM TO BE SOLVED: To provide a liquid viscosity measuring instrument that can accurately measure the viscosity of a liquid by preventing the electric characteristics of a piezoelectric sensor device from being affected by mechanical actions during the course of measurement. SOLUTION: In this liquid viscosity measuring instrument which measures the characteristics of the liquid, the piezoelectric sensor device has an electrical contacting spot for electric control section which is completely dipped in the liquid to be measured and has a resistance to the liquid. A power feeder has a resistance to the liquid and is connected to an electronic controlling/evaluating device on the outside of the liquid and also to the contacting spot of the sensor device by using an appropriate conductive adhesive section provided with a metallic piece.

摘要： The invention relates to a sensor system used for the sensory online detection of the corrosive action of the oil during the service life thereof in the oil circuit of a machine. One of the oil replacement criteria for machines using large quantities of oil (i.e. the machine has an oil filling that can be replaced during maintenance) is the acidification (or corrosiveness) of the oil. For internal combustion engines operating with biofuel, this is often the main criterion for carrying out an oil change. The inventive sensor system uses at least two flat elements (2 to 6) consisting of electroconductive materials which can be structured in a plane manner and/or in the cross-section. At least one of said flat elements is used as a corrosion sacrificial element (2) for detecting the corrosion. Said flat elements are switched or connected to the electronic evaluation system (or to each other) in an electrical measuring circuit. The corrosive material loss is measured by the change in the electrical characteristics of the flat elements (e.g. electrical resistance or capacitance) used as corrosion sacrificial elements , preferably detected in a plane manner.

摘要： Vehicle-borne apparatus determines the concentration of volatile components (12) of engine oil (10), where the concentration of volatile components depends on the total number of bases of the oil (10). The apparatus comprises a semiconductor sensor (20) with a sensitive layer containing metal oxides, a surface acoustic wave (SAW) sensor, or a chemiluminescence sensor. Preferred Features: The apparatus comprises a first membrane (2) that is impermeable to the oil but permeable to volatile components (12) comprising acetaldehyde, acetone, acetic acid and/or benzaldehyde. The first membrane (2) is wetted by the oil, and separates a gas chamber (30) from the region (40) containing the oil.

摘要： In a method for calculating a time-related fill level signal (h(t)) from a sensor signal (s(t)) of a fill level sensor for detection of the fill level of a liquid, the time-related fill level signal (h(t)) is calculated as a function of the sensor signal (s(t)) and the modeled runoff behavior of the liquid on the fill level sensor.
