  • Sensor with a planar effective sensor surface
    Publication number: 20020175802
    Abstract: A sensor with a planar effective sensor surface, for direct contact with the measuring medium. To achieve the effect that the sensor surfaces or the surfaces of the passivation layer applied to them are much less susceptible to dirt, the sensor surface is coated with a nanostructured surface, or a passivation layer, of reduced adhesiveness, structured in a way similar to the surface of a lotus leaf.

  • Apparatus for measuring the flow velocity of gases and liquids
    Patent number: 4449402
    Abstract: There is described an anemometer for the measurement of the flow velocity of gases and liquids particularly for the measurement of the intake air of internal combustion engines whereby the heated resistances are film resistance made of a metal layer and carrier, should have the shortest possible response time. This is attained by so dimensioning the flow paths (6) in the metal layer (1) that the resulting resistance per unit of surface area stands in a constant ratio to the local heat transfer coefficient.

  • Holding device for electrical thin layer resistance
    Patent number: 4395586
    Abstract: For the secure positioning combined with a quick regulation of the thermal equilibrium of thin layer resistances, especially in hot film anemometers, there are used holding devices in which the thin layer resistance 2 is rested on at least three pointed supports 4 of a holding clamp 1 and is pressed on at least two of the supports 4 with clips provided with spikes.
