Introduction A gas alarm is a flameproof safety device capable of rapidly, reliably, stably and continuously detecting 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, preventing 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. After being processed by the alarm, the voltage signal uploads data and displays it on the screen. When the concentration reaches the set action value, the alarm triggers an alert and drives external devices. A gas alarm is a fixed instrument that can continuously detect oxygen concentration or the concentration of toxic, harmful, flammable and explosive gases 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 being amplified, the signal undergoes A/D sampling, temperature compensation and intelligent calculation by the CPU to process the measurement result. If the measured value exceeds the set alarm concentration value, an alarm signal will be sent out. The gas alarm features a dual-chamber design, a dedicated imported sensor, and the sensor adopts a modular design, 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 sites for equipment.
Features Ingenious structural design, extremely easy to install; Upper and lower alarm points can be set arbitrarily within the full range; Flameproof design, suitable for hazardous locations in Zone 1 and Zone 2 of industrial plants; The gas alarm can be optionally equipped with a liquid crystal concentration display, showing the concentration in real time on site; The gas alarm can be optionally equipped with a dedicated flameproof acoustic-optic alarm to realize on-site acoustic-optic alarm; Meets customers' requirements for arbitrary ranges from 1 to 99999 and all gas detection needs; Two sets of normally open dry contact outputs, used for controlling contactors of fans or solenoid valves; Exquisite power supply design, pure SMT component surface mount technology, ensuring stable product performance; The sensor uses imported gas-sensitive components, with high precision, long service life, small zero drift, fast response time, can work continuously for a long time, has a compact body, is easy to operate, and has good anti-poisoning 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 the detection of dozens of gases, and can display the gas name; Gas units: ppm, LEL%, VOL%, mg/m³; International standard (4～20)mA signal can be directly connected to the plant DCS system, and RS485 digital signal can be connected to the plant upper computer;
