METHOD OF MEASUREMENT OF PHYSICAL QUANTITY AND DEVICE FOR ITS REALIZATION

摘要

FIELD: measurement technology. SUBSTANCE: invention is meant for technology employing computer for reception and processing of metrological information of general assignment. Measured value acts on sensitive element of device meant for measurement of physical quantity. Change of electric parameter of element leads to change of parameter f electric oscillatory process in former of variable voltage which frequency of output voltage changes accordingly. Mentioned voltage goes from output of level converter to input of audioadapter of computer which configuration corresponds to Multimedia Personal Computer specification, is processed and value of measured quantity is determined with usage of software and information on transmission characteristics of former and on parameters of frequency-setting elements. EFFECT: increased functional reliability and accuracy of method and device. 6 cl, 4 dwgs
