Title: Inductive transducers with magnetic fluids
Published In: Sensors and Actuators A, Vol. 32, pp. 678-681
Description: Inductivetransducers are considered, which have as essential components electrical coils partially filled with magneticfluid. It is shown that the displacement of the magnetically permeable liquid core of relative height t of a pair of identical coils produces an inductance difference ?L(t) = L(t) - L(1 - t), which has a practically linear dependence on t for enough small values of the radius-to-length ratio of the coils. A design algorithm has been applied to construct various laboratory transducer models for inclination angle (from 0–2 to 0–200 arcmin), differential pressure (from 0–2 to 0–200 mm H2O) and volumetric flow rate (from 0–3 to 0–105 1/h), whose resolutions attain 1 arcsec, 1 µm H2O and 12 cm3/h, respectively.
