Introduction A gas detector is a flameproof safety device that can rapidly, reliably, and stably detect gas concentration continuously. When the detected gas concentration reaches the pre-set 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 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 equipment. A gas detector is a fixed instrument that can continuously detect oxygen concentration or toxic, harmful, flammable, and explosive gas concentrations 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 undergoes A/D 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 value, an alarm signal will be issued. 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. Features Ingenious structural design, extremely easy to install; Arbitrary upper and lower alarm points can be set 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 to show the concentration in real time on-site The gas detector can be optionally equipped with a special flameproof audible and visual alarm to realize on-site audible and visual alarm Meets customers' arbitrary range requirements 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, making the product performance stable; The sensor adopts imported gas-sensitive elements, with high precision, long service life, small zero drift, fast response time, long-time 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 carried out through the controller without opening the cover 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 upper computer
