Introduction A gas alarm is a flameproof safety device capable of rapidly, reliably, stably and continuously detecting gas concentrations 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 the gas alarm: The alarm installed on-site operates with power supply. When a gas leak occurs, the sensor converts the detected leakage 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 oxygen concentration or toxic, harmful, flammable and explosive gas concentrations in the working environment. The gas alarm adopts a diffusion method to real-time convert the gas concentration signal at the monitoring point into an electrical signal. After the signal is amplified, it undergoes AD sampling, temperature compensation and intelligent calculation by the CPU, and then the measurement result is processed. If the measured value exceeds the set alarm concentration, an alarm signal will be sent out. The gas alarm adopts a dual-chamber design, special imported sensors, and the sensors are modularly designed, making calibration and adjustment 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 site equipment. Features Ingenious structural design, extremely easy to install; Upper and lower alarm points can be set arbitrarily within the full range; Flameproof design, can be used in hazardous areas 1 and 2 of factory conditions The gas alarm can be optionally equipped with an LCD 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 any range requirements between 1 and 99999 and all gas detection needs of customers; Two sets of normally open passive contact outputs, used to control the AC contactors of fans or solenoid valves Exquisite power supply design, pure SMT component surface mount technology, making the product performance stable; The sensor uses imported gas-sensitive elements, with high precision, long service life, small zero drift, fast response time, can work continuously for a long time, small size, convenient operation, and good anti-poison performance The alarm point adjustment, zero adjustment and target point calibration of the transmitter can be performed without opening the cover through the controller 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
