Carbon monoxide transducer for mine
This product is a new generation of intelligent carbon monoxide sensor, using standard signal output, and various power of domestic instrument and monitoring system, carbon monoxide concentration continuous monitoring flammable in the work environment. Has the characteristics of long communication distance, contact large output power, local display, sound and light alarm, infrared remote control to adjust, convenient to install and use.
Product features and uses:
GTH1000 type carbon monoxide sensor (hereinafter referred to as the instrument), the embedded micro controller technology, designed and manufactured according to the new standard, and various types of supporting the use of coal mine safety monitoring system, continuous online monitoring presence of carbon monoxide concentration flammable combustible gas mixture in the environment. Has the functions and features of local display, sound and light alarm, infrared remote control to adjust, frequency signal output, digital signal output.
Working principle.
When the instrument is placed in the presence of carbon monoxide gas environment, carbon monoxide gas into the gas chamber through the instrument housing window, electrochemical sensor air chamber to diffuse and carbon monoxide gas generated in the reaction and the measured gas concentration is proportional to the electric signal. Signal by linear amplifier input A/D converter, the microprocessor for data processing, the digital display of the carbon monoxide concentration, and the signal output circuit output signal, and other equipment. The alarm circuit instrument is composed of a buzzer, light-emitting diodes and a drive circuit, when the concentration of carbon monoxide exceeds the set alarm point, the instrument will give an alarm signal.
