FIELD: electrical engineering. ^ SUBSTANCE: invention proposes operating parametres transducer to be connected to process line and transmit parametres indication over transmission line. Said transducer comprises, i.e. parametre sensitive element that can be connected to process line to generate parametre analog indication, ADC connected to parametre sensitive element and outputting digital data that represent analog data from aforesaid sensitive element. Note here that said digital data includes digital data flow and output circuits designed to output process parametre signal, microprocessor arranged in aforesaid transducer. Note here also that microprocessor is connected with ADC and configured to calculate spectral density of digital data flow and generate diagnostics data in response to power spectral density signal. ^ EFFECT: higher reliability and accuracy of diagnostics. ^ 23 cl, 12 dwg |
