Directory of engineer Annotation << Back Miniature Pressure Scanners V.A. Kolesnikov, A.E. Nazarov, G.V. Biryukov The article briefl y describes the stages of evolution of multichannel systems measuring pressure. The review of perspective version of small-sized scanners of pressure is presented. The principles of construction, a design and the main technical characteristics of the miniature multichannel scanners of pressure with the digital interface and the slot of a memory card were considered. The scanners can be used for measurement of fi elds of pressure in experimental aerodynamics and in other cases, where is necessary measurement of values of pressure at the same time in a large number of points. The special attention is given to basic advantages of digital version. He has possesses wide functionality and satisfi es to the majority of requirements for miniaturization, precision and speed. In the case (54,3×13,3×12,3) mm are mounted 32 pressure sensitive elements, which is less than 0.3 cm3 per channel. It is mentioned in article and about perspective developments of scanners and converters of pressure, including subminiature pressure sensitive elements – fl exible fi lm converters of pressure. Also important is the fact that the products listed in the article are developed and manufactured in Russia by domestic sensitive elements and using a primary domestic components. Keywords: small-sized scanner of pressure, sensitive element of pressure, aerodynamic experiment, multiplexer, temperature sensor, thermostat, digital interface, algorithmic temperature compensation error, pneumatic port, microcontroller, precision rating.
