Zusammenfassung: | The utility model discloses a feed line material level sensor for farms, which comprises a main CPU (central processing unit), a power circuit, an adjusting circuit, an inductive head filter circuit and a signal processing circuit, an SCR (selective catalytic reduction) output circuit is arranged in the power circuit, one side of the inductive head filter circuit is connected with the adjusting circuit, and the other side of the inductive head filter circuit is connected with the signal processing circuit. According to the utility model, the oscillation frequency is changed by using the potentiometer to adjust the voltage of the capacitor three-point oscillator circuit composed of the induction sheet and the triode, thereby improving the interference caused by the traditional mode of adjusting the amplification factor of the circuit; the power supply circuit adopts a rectification circuit, an RC bridge filter, a special MOS chip BSP125 and a reference voltage stabilization integration TL431 to form a reliable |
