Magnetic and Eddy Current Type Transducers for use in Industrial Electronics

The characteristics of magnetic pickups are discussed with regard to practical application. The principles of operation are discussed briefly and the output voltages illustrated are taken under actual operating conditions at various speeds. The mechanical construction is covered in progressive steps. Various models for both low and high temperature applications are described. A brief description of the principle of operation of the eddy current or proximity pickup is presented. The operating clearance range is given for various models. A description is given of the use of proximity pickups for counting work parts, for controlling feed and for initiating steps of operation in automated factories.
