Deskripsi
In order to obtain accurate signal of NAMUR speed sensor, the paper designed a kind of signal acquisition circuit based on PIC18F2480 single-chip microcomputer, and gave software design process of the circuit. The signal acquisition circuit can collect frequency signal with 0～600 Hz, and can on-line monitor conditions of break, short circuit or normal running of sensor.
