Zusammenfassung: | measurement technology. SUBSTANCE: device incorporates transducer 1 with pulse former 2, logic double-input AND gates 3, 4, 9, frequency discriminator 5, reference frequency generator 6, counting flip-flop 7, electron key 8, counter 10, frequency divider 11, digital indication unit 12. Output of frequency divider 11 is connected to second input of second logic AND gate 4 which first input is connected to first input of electron key 8 and which output is connected to second input of frequency discriminator 5. First input of discriminator 5 is connected to output of first logic AND gate 3 which first input is connected to output of pulse former 2 and which second input is connected to inversion output of counting flip-flop 7. Unit output of flip-flop 7 is connected to first input of third logic AND gate 9 which second input is connected to output of pulse former 2 and which output is connected to input of frequency divider 11. EFFECT: increased measurement precision. 1 dwg |
