Automatic calibration of the recording-channel sensitivity in piezoelectric measuring systems

Brief Communications and Letters to the Editor


The above calibration circuit is suitable for obtaining by a simple method the instantaneous sensitivity of recording channels in piezoelectric installations at the instant of recording the process.

The error due to connecting the calibrator circuit across the piezoelectric transducer input does not exceed the errors produced by other elements of the recording channel.

The calibrating pulse amplitude U(lk) is determined by the stabilitron's stabilized voltage and the ratio of capacitances Ck and\(C_{c\Sigma } .\)
