Methane carbon monoxide sensor
1. Overview
The methane carbon monoxide sensor is an intelligent intrinsically safe monitoring instrument controlled by a microcontroller and has an infrared remote control function. It is suitable for use in coal mine underground mining working faces, return air tunnels, electromechanical chambers and other environments containing methane and carbon monoxide gases, and can continuously measure the concentrations of methane and carbon monoxide. It can not only be used with the coal mine safety monitoring system produced by our company, but also can be used with other types of coal mine safety monitoring systems and mining substations and various power outages that have passed joint inspection.
2. Features
Stable performance: The methane detection part of this instrument uses a carrier catalytic element, and the carbon monoxide detection part is an imported gas sensor based on the electrochemical method. It has stable performance, long life, and is resistant to Strong vibration and impact force, not affected by pressure
, high sensitivity and high performance sensor elements plus automatic nonlinear compensation of the instrument's internal software, the instrument has high sensitivity for the detection of methane and carbon monoxide
High reliability. This instrument has functions such as power-on self-check, automatic zero stabilization, and accuracy correction. It adopts infrared remote control for adjustment. The whole machine does not have any adjustment holes. The zero point, accuracy adjustment, and alarm value setting of the instrument are all controlled by infrared remote control. device control. It can avoid opening the cover for debugging, reduce mechanical damage, improve the sealing of the whole machine, and extend the service life of the instrument. It has a wide measuring range of methane (～carbon monoxide (～)) and the remote control is compact and easy to carry. .
