This paper describes steps involved in the design and realization of a new type of pressure sensor based on the optical fiber Bragg grating. A traditional pressure sensor has very limited usage in heavy industrial environments, particularly in explosive or electromagnetically noisy environments. Utilization of optics in these environments eliminates all surrounding influences. An initial motivation for our development was the research, experimental validation, and realization of a complex smart pressure sensor based on the optical principle. The main benefit of this solution consists of increasing sensitivity, resistance to electromagnetic interference, dimensions, and potential increased accuracy.
Φ Abstract --High-speed ranging requires various equipment, for example compressors, turbo-compressors and turbocirculators nowadays. Solutions using electrical drive with gearboxes is limited by technical feasibility, lifetime and maintenance of gearbox systems. Thanks to development of frequency converters is possible to build direct high-speed electrical drive. This paper is dealing with design of high-speed solid rotor cage induction machine for running 6 kW, 120 000 rpm helium turbo-circulator. Design of high speed electrical machine for TC is described from requirement specification to manufacturing. Results of mechanical, electromagnetic and thermal calculations are given. Proposed design approached can be used in various application in which high speed electrical machine is required.
