Non-contacting two-channel speed sensor FA52 with stainless steel flange housing and sensor tube NORIS Scan type Eddy current principle (FAW52) Application range Speed sensors type series FA[..]52 are especially designed for use in transport technology and machinery and equipment. Speed sensors type FAH52 measure the speed of ferromagnetic (e. g. steel), and type FAW52 of electrically conductive toothed wheels (e. g. aluminium). Furthermore, they can be used to measure any movement of ferromagnetic or electrically conductive materials, e. g.: • Toothed wheels with different tooth forms • Bolt heads • Lands detects holes, openings or grooves • Impulse bands for plain shafts (accessories) Specific features • Type FAW[..]:Without magnetic preload and thus, no accumulation of metal chips • Type FAW[..]:Scanning of all electrically conductive materials (steel or aluminium) • Excellent vibration and shock resistance and double protection of the sensor head • Robust and high quality housing: IP69 pressure-tight and individually tested at 5 bar (for details see technical data) • Connection outlet straight or lateral; with protective tubing on request • Due to its design and type approval according to DIN EN 50155 especially suitable for transport technology Speed sensors of the FA[..]52 series operate according to different measuring principles, depending on the sensor type: A coil with a high frequency alternating current supply is integrated in the sensor head. An electromagnetic field is produced with its field lines emitted from the sensor surface. Eddy currents are induced as the electrically conductive scanning object moves past the sensor face. These eddy currents in the scan object create a magnetic field opposing the coil field of the sensor. As a result, a voltage is detected on the sensor coil and analysed. Difference-hall-effect principle (FAH52) Two closely spaced Hall elements are located on the sensor chip. The field of the magnet generates a constant voltage in the Hall elements. Ferromagnetic objects with an interrupted surface moving past the Hall elements cause the Hall voltage to change. When the moving part covers a Hall element and the other does not, a differential voltage is generated to provide a measuring signal. The frequency of this signal is proportional to the speed of movement (rotational speed). The difference-hall-effect principle is direction sensitive.
