PRIMARY INFORMATION TRANSDUCER Russian patent published in 1998 - IPC

FIELD: instrumentation, automated measurement and test of various nonelectric values that can be converted from energy of external source of one type to electric energy of data collecting and processing systems and control systems operating in real time. SUBSTANCE: primary information transducer has two sensitive elements, one being variable capacitor 1 and the other one- variable resistor 3 placed into different circuits of digital RC generator 2 of rectangular pulses which output is connected to input of frequency divider 4 made of N scale-of-ten counters 6, base-of-two counter and digital frequency meter 5 manufactured in the form of n-digit binary-decimal counter of digital indicator 4. EFFECT: enhanced operational efficiency and reliability. 4 wdgs
