Position Sensing: Angle and Distance Measurement for Engineers - Tapa dura

Sinopsis

Describes the fundamental principles of angle and distance measurement for electronic and mechanical engineers and students. The digital display of position data and the digital control that comes with it have become commonplace. The widespread availability of low-price controllers has meant that measurement processes have also become available to a widening range of manufacturers and users. Today there is hardly a branch of engineering in which automatic measurement and control does not take place, for example machines for woodworking, metalworking and processing plastics, printing machines, packing machines and food processing machines. In addition, high-precision automatic position-sensing systems are being used to sense and control the position of radio telescopes, astronomical telescopes and radar antennae, to control integral switching in production systems, and in automatic measuring and testing machines. In all branches of technology where controlled movement takes place, position sensing is at the forefront. Further examples are the navigation of ships, vehicles and aircraft, and the control of conveyor and storage systems. The electrical measurement of angles and distances is an interesting interdisciplinary field as widely differing physical principles can be used to produce the measurement base and its reading and to evaluate and process the signals obtained. This volume is intended both for the mechanical engineer, who has to include measurement processes as an integral part of his design, and the measurement and control technician who, in widely differing engineering tasks, may be confronted with the problem of positioning sensing, often in relation to positioning control and the security of data transfer and storage.
