Introduction A gas detector is a flameproof safety device that can quickly, reliably, and stably continuously detect gas concentration in industrial production. When the detected gas concentration reaches the preset alarm value of the gas detector, the detector will issue an alarm and drive external equipment to remind on-site staff to take necessary protective measures, which can prevent gas-induced combustion accidents. Working principle of the 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 issue an alarm and drive external equipment. A gas detector is a fixed instrument that can continuously detect the oxygen concentration or the concentration of toxic, harmful, flammable and explosive gases in the working environment. The gas detector adopts a diffusion method to convert the gas concentration signal at the monitoring point into an electrical signal in real time. After the signal is amplified, it is subjected to AD 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 issued. The gas detector adopts a dual-chamber design, special imported sensors, and the sensors adopt a modular design, which makes 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 site equipment. Features Clever 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 locations of Class 1 and 2 in factory conditions The gas detector can be optionally equipped with a liquid crystal concentration display, which displays the concentration in real time on site The gas detector can be optionally equipped with a special explosion-proof sound and light alarm to realize on-site sound and light alarm Meets customers' requirements for any range between 1-99999 and all gas detection needs; Two sets of normally open passive contact outputs are used to control the AC contactors of fans or solenoid valves Exquisite power supply design, pure SMT component patch process, making the product performance stable; The sensor adopts imported gas-sensitive components, with high precision, long service life, small zero drift, fast response time, long-term continuous operation, small size, convenient operation, and good anti-poisoning performance The alarm point adjustment, zero point adjustment and target point calibration of the transmitter can be carried out through the controller without opening the cover Suitable for dozens of gas detections, and can display gas names; gas unit names are 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
