MEASURING TRANSDUCER Russian patent published in 1996 - IPC

FIELD: measurement technology; transducers for measuring various physical quantities built around sensors or sensing elements whose output signals are periodic pulse frequencies. SUBSTANCE: transducer has two frequency signal generators at least one of whose frequencies depends on parameter under measurement. In addition, generator is provided with two D flip-flops, pulse counter, reset pulse shaping circuit, and duty-factor-to-voltage changer that has low-frequency filter and switches; input of first of second one is grounded; outputs are connected to input of low-frequency filter. EFFECT: improved reliability and stability of transducer and linearity of its performance characteristics. 2 cl, 1 dwg
