Introduction A gas detector 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 detector, the detector will trigger 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 gas detector: The detector installed on-site operates with power supply. When gas leakage occurs, the sensor converts the detected leakage 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 equipment. 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 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 sent out. 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 on-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 under factory conditions The gas detector can be optionally equipped with a liquid crystal concentration display, which shows the concentration on-site in real time The gas detector can be optionally equipped with a special flameproof acoustic-optic alarm to realize on-site acoustic-optic 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 chip 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 body, convenient operation and 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 dozens of gas detections, and can display the gas name; 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 upper computer
