FIELD: machine building.
SUBSTANCE: group of inventions relates to process parameter transmitters. For this purpose, process parameter transmitter includes analogue-to-digital converter (ADC), which receives sensor signal provided by sensor, which reads process parameter and converts sensor signal into digital signal. Processor receives digital signal and provides measurement output signal, corresponding to digital signal. Noise detector receives sensor signal and generates first value, corresponding to number of positive noise events relative to positive threshold value, and second value, corresponding to number of negative noise events relative to negative threshold value. Processor evaluates noises calculation and generates output noise signal, corresponding to detected noise based on first and second values.
EFFECT: technical result is increasing of process parameter measuring accuracy.
