Design of Mine-used Electrochemistry CO Sensor

Abstract

The paper analyzed structure, reaction mechanism and working principle of electrochemistry CO sensing element, put forward a design scheme of mine-used electrochemistry CO sensor, and introduced design of main circuits of the sensor. The sensing element of the sensor is designed with three-electrode mode, so the sensor has advantages of high sensitivity and good linearity. And the sensor can retain high measurement accuracy when CO's volume fraction is low, which satisfies requirement of coal mine usage.
