DIAGNOSTIC DEVICE FOR MEASURING TRANSDUCER Russian patent published in 2021 - IPC H03K5/19 

FIELD: measurement.

SUBSTANCE: invention relates to the field of measuring technology, namely to measuring transducers with the frequency form of output signals. Device comprises two frequency-setting elements, made in the form of piezoelectric resonance sensors with current-conducting paths, and a diagnostic unit of frequency-setting elements is provided, which provides pulse method of diagnostics of conductive paths, in this connection distortion of frequency characteristic of conversion of measured parameter is excluded.

EFFECT: technical result consists in providing the possibility of checking in the pulse mode the operability of the frequency-setting elements of the measuring transducer and thereby the converter as a whole at all operating stages.
