Design of Intrinsic Safety Current-frequency Conversion Circuit Based on PIC Single-chip Microcomputer
In view of problem of diversity existed in signal output forms of analog sensor, an intrinsic safety current-frequency conversion circuit based on PIC single-chip microcomputer was designed. The circuit uses intrinsic safety power supply, and converts analog current signal into voltage signal throug...
