Published:2011/6/24 7:57:00 Author:Nicole | Keyword: bearing fault, detector | From:SeekIC

The bearing fault detector circuit is composed of bearing testing sensor, signal process circuit and acousto-optic circuit, it is shown in the figure 8-79. The signal process circuit is made of input socket XS, sound control integrated circuit IC1, capacitors C1-C3, resistors R1, R2 and potentiometer RP. The acousto-optic circuit consists of transistors V1, V2, LED VL1, VL2, audio power amplifier integrated circuit IC2, resistors R3, R4, capacitor C4, diode VD1, VD2 and loudspeaker BL. The sensor's sensitivity can be changed by adjusting RP.
