IntroductionA gas detector is a flameproof safety device capable of rapidly, reliably, and stably detecting gas concentration continuously in industrial production. When the detected gas concentration reaches the pre-set alarm value of the gas detector, the detector will trigger an alarm 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 Detector: The detector installed on-site operates with power supply. When a gas leak occurs, the sensor converts the detected leak amount into a corresponding voltage signal for output. After the voltage signal is processed by the detector, the data is uploaded and displayed on the screen. When the concentration reaches the set action value, the detector will trigger an alarm and drive external devices. A gas detector is a fixed instrument that can continuously detect the concentration of oxygen, toxic and harmful gases, or flammable and explosive gases in the working environment. The gas detector 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 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. The gas detector features a dual-chamber design, special imported sensors, and the sensors adopt 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 on-site equipment.
FeaturesIngenious structural design, extremely easy to install; Upper and lower alarm points can be set arbitrarily within the full range; Explosion-proof design, can be used in hazardous areas 1 and 2 under factory conditions; The gas detector can be optionally equipped with a liquid crystal concentration display, which shows the concentration in real-time on-site; The gas detector can be optionally equipped with a special explosion-proof audible and visual alarm to achieve on-site audible and visual alarm; Meets customers' requirements for any range from 1 to 99999 and all gas detection needs; 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, ensuring stable product performance; The sensor adopts imported gas-sensitive components, with high precision, long service life, small zero drift, fast response time, long-time continuous operation, small size, convenient operation, and good anti-poisoning performance; The alarm point adjustment, zero adjustment, and target point calibration of the transmitter can be performed via 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 factory DCS system, and RS485 digital signal is connected to the factory host computer;
