Non-contacting two-channel speed sensor type FA13 with stainless steel screw-in thread NOR/S Scanning type Application range Series FA13 speed sensors are mainly used in the following areas: Shipbuilding industry and machinery and equipment. They usually measure the speed of ferromagnetic toothed wheels. Furthermore, they can be used to measure any movement of ferromagnetic parts, e. g.: • Toothed wheels with different tooth forms • Bolt heads • Holes, openings or grooves • Impulse bands on plain shafts (accessories) Specific features • High quality and robust stainless steel housing: IP66/68/69 • Excellent vibration and shock resistance • High degree of EMC immunity for difficult electrical environment • Variable lengths, threads and electrical connections • Detection of very low speed (near zero speed) • Due to its design and its approvals especially suitable for shipbuilding industry Measuring principles Speed sensors of the FA[..]11 series operate according to different measuring principles, depending on the sensor type: Difference-hall-effect principle (type FAH11) Two closely spaced Hall elements are located on the sensor chip. The field of a magnet generates a constant voltage in the Hall elements. Ferromagnetic objects with an interrupted surface as they pass the Hall elements cause the Hall voltage to change. When the moving object covers only one Hall element, a differential voltage is generated to provide a measuring signal. The frequency of this measuring signal is proportional to the speed of movement (rotational speed). The difference-Hall principle is direction sensitive. Inductive-magnetic principle (type FAJ11]) The measuring element consists of a sensing coil and an iron core with an attached permanent magnet. Ferromagnetic objects with an interrupted surface as they pass cause the constant field of the magnet to be changed and induce a voltage in the sensing coil. The frequency of this signal is proportional to the speed of movement (rotational speed). The inductive-magnetic principle is direction independent.
