Beschreibung
Zusammenfassung:	automation engineering. SUBSTANCE: device has metal casing and sensitive member coupled with it, high frequency oscillator, unit for building signal and signal treatment processor which input is connected to output of the unit for building signal, the second frequency source conversion oscillator and mixer which inputs are coupled with oscillators outputs and the output is connected to input of the unit for building signal. The sensitive member is connected to the first oscillator circuit. The second oscillator has features for tuning frequency and its tuning input is connected to the signal processor output. EFFECT: improved sensitivity and noise immunity. 1 dwg
