A carbon monoxide transmitter detects CO gas concentration using an electrochemical or semiconductor sensor. When CO molecules contact the sensing element, a chemical reaction occurs, generating an electrical current proportional to the gas concentration. The transmitter’s electronics process this signal and convert it into a standardized output, such as 4–20 mA or digital communication. This output is sent to monitoring systems to trigger alarms, ventilation, or shutdown procedures, ensuring safety in industrial, commercial, and residential environments.
