Research on Multi-Functional Weak Current Real-Time Detection of Gas Corrosion Sensor

Abstract:

At present, the detection of weak corrosion current is not perfect and automated, to solve the problem, this paper put forward and designed a kind of weak and wide-range corrosion current real-time detection circuit with functions of automatic switching range . By choosing low bias current and high precision operational amplifier, using I - V conversion technology transform the weak current into voltage, then do voltage signal acquisition, using the SD card module and electronic analog switch combined with single chip microcomputer to realize real-time and auto-switching detection of the corrosion current. This circuit has good real-time performance and accuracy, and can achieve the corrosion current value that was outputted by gas corrosion sensor well.
