Integrated gas detector with sound and light alarm

Integrated gas detector with sound and light alarmThe carbon monoxide gas concentration detection transmitter adopts a cast aluminum explosion-proof shell as the protective shell, and has the characteristics of small size, light weight, and easy installation. The electrochemical carbon monoxide sensor is used as the carbon monoxide concentration detection element to convert the carbon monoxide concentration content into an electrical signal. The weak electrical signal is amplified by an amplifier and sent to a microprocessor for signal processing, and then converted into a standard (4~20) mA current signal, which is transmitted to the required upper computer equipment. The connection between the transmitter and the upper equipment only requires a three core cable, making equipment debugging, installation, and maintenance faster and more convenient. In addition, this transmitter has strong electromagnetic interference resistance, precise measurement, rapid response, long service life, stability and reliability, making it very suitable for places such as petrochemical, metallurgical, environmental monitoring that require monitoring of carbon monoxide concentration.
