Infrared carbon dioxide sensor
1. Overview
The infrared carbon dioxide sensor is an intrinsically safe electronic sensor that adopts the infrared principle, intelligent control by an embedded microcontroller, and a three-digit digital tube display. This instrument is suitable for use in explosive gas environments such as underground mining working surfaces, return air tunnels, and electromechanical chambers, and can continuously measure carbon dioxide concentration. The instrument can measure and display the instantaneous concentration of carbon dioxide, alarm when it exceeds the limit, and output a frequency signal proportional to the measured carbon dioxide content. The instrument has the characteristics of wide measuring range, stable performance and high reliability. It can be used with various coal mine safety monitoring systems and power outage instruments.
