Working principle of carbon monoxide gas monitoring equipment:
CO concentration changes in the air → Carbon monoxide sensor detects CO concentration → Converts concentration into current/voltage signal→ Signal amplification (one-stage or two-stage amplification) → MCU receives and processes signal → Compares with preset threshold → If exceeds the standard, triggers alarm → Drives LED light + speaker/buzzer to emit sound and light alarm → Starts external equipment such as solenoid valve and exhaust fan
Advantages of CMC industrial carbon monoxide gas detection system:
1. Real-time detection of carbon monoxide concentration
The fixed gas alarm can monitor carbon monoxide concentration 24 hours a day, issue an alarm in real time, and ensure the safety of employees and equipment.
2. Adopt Honeywell sensor, accurate and reliable
We use the well-known brand Honeywell sensor to ensure the accuracy and reliability of the detection results, in line with international safety standards.
3. Sound and light dual alarm
Sound and light dual alarm, sound and light prompt at the same time, to ensure that the danger signal is clear and visible, and respond quickly.
4. High sensitivity and rapid response
Compared with portable detectors, fixed equipment has higher sensitivity and faster response, and can remind you at the first time when the carbon monoxide concentration exceeds the standard.
5. Strong stability and simple maintenance
The fixed product design is durable and has strong anti-interference ability. It is easy to maintain and calibrate, and is stable and reliable for long-term use.
Application industries of toxic and combustible gas detectors:
Fixed toxic and combustible gas alarms can not only detect carbon monoxide concentrations, but are also widely used in petroleum, chemical, metallurgical, gas and other industries to detect methane, hydrogen sulfide, ammonia, chlorine and other toxic, harmful and combustible gases, effectively ensuring safe production.
