Introduction A gas alarm is a flameproof safety device that can rapidly, reliably, stably and continuously detect gas concentration in industrial production. When the detected gas concentration reaches the preset alarm value of the gas alarm, the alarm will trigger an alert and drive external devices to remind on-site staff to take necessary protective measures, which can prevent gas-induced combustion accidents. Working Principle of Gas Alarm: The alarm installed on-site operates with power supply. When a gas leak occurs, the sensor converts the detected leakage amount into a corresponding voltage signal for output. After the voltage signal is processed by the alarm, the data is uploaded and displayed on the screen. When the concentration reaches the set action value, the alarm will trigger an alert and drive external devices. A gas alarm is a fixed instrument that can continuously detect the concentration of oxygen or toxic, harmful, flammable and explosive gases in the working environment. The gas alarm adopts a diffusion method to convert the gas concentration signal at the monitoring point into an electrical signal in real time. After this signal is amplified, it is processed by the CPU through AD sampling, temperature compensation and intelligent calculation. If the measured value exceeds the set alarm concentration value, an alarm signal will be issued. The gas alarm features a dual-chamber design, special imported sensors, and the sensors adopt a modular design, making calibration and verification more convenient. It has superior performance, high stability, can output multiple sets of signals, and is easy to install and maintain, meeting the high reliability requirements of industrial on-site equipment. Features Ingenious structural design, extremely easy installation; Upper and lower limit alarm points can be set arbitrarily within the full range; Flameproof design, suitable for hazardous areas 1 and 2 in factory conditions The gas alarm can be optionally equipped with a liquid crystal concentration display, which shows the concentration in real time on-site The gas alarm can be optionally equipped with a special flameproof acoustic-optic alarm to realize on-site acoustic-optic alarm Meets customers' arbitrary range requirements from 1 to 99999 and all gas detection needs; Two sets of normally open dry contact outputs, used for controlling contactors for fans or solenoid valves Exquisite power supply design, pure SMT component surface mount technology, ensuring stable product performance; The sensor uses imported gas-sensitive elements, with high precision, long service life, small zero drift, fast response time, long-term continuous operation, compact body, convenient operation and good anti-poison performance The alarm point adjustment, zero adjustment and target point calibration of the transmitter can be performed through the controller without opening the cover Suitable for dozens of gas detections and can display gas names; Gas unit names: ppm, LEL%, VOL%, mg/m³ International standard (4～20)mA signal can be directly connected to the factory DCS system, and RS485 digital signal is connected to the factory host computer
