    摘要: The invention is directed to a flow sensor having a heater, two temperature measuring sensors, a heater temperature sensor and a medium temperature sensor. A control circuit is provided which controls the overtemperature of the heater in dependence upon the temperature of the flowing medium. With this arrangement, the influence of the temperature dependency of the following on the sensor characteristic are compensated: viscosity, thermal conductance and thermal capacity of the medium. The relationship between the heater temperature and the temperature of the medium is adjusted in a slightly nonlinear manner by means of special evaluation circuits. In this way, a further improvement of the temperature compensation is obtained.

    摘要: A mass flow sensor detects the intensity of a media flow. The mass flow sensor includes a measurement chip, with a dielectric membrane and a frame of monocrystalline silicon. At least one heater is arranged on the membrane. The measurement chip is installed in the in-flow channel of a housing. By means of the structure of the housing, contamination of the measurement chip is reduced, thermal equalization with the media flow is improved, the resistance of the sensor to sudden pressure variations is increased, and the dielectric contacts are improved.

    摘要: An improved temperature sensor is designed for the sensitive detection of temperature changes. The temperature sensor includes a frame 9 of monocrystalline silicon and a dielectric diaphragm 13 stretched on it. A monocrystalline silicon structure 35 is disposed on or under the dielectric diaphragm which is used for measuring the temperature. In the course of this, the Seebeck effect, as well as the temperature dependence of the electrical resistance, can be used for detection of any temperature changes.

    摘要: A method for identifying sensors on a bus by a control unit, as well as a control unit and a sensor for doing this. The sensors, in this instance, send physical useful data to the control unit as the basis for the control of a function. Furthermore, the physical useful data are compared to one another and/or to specified expected values, and the identification of the sensors by the control unit takes place with the aid of the comparison and based on characteristic differences in the physical useful data for the sensors.
