Introduction A gas detector is a flameproof safety device capable of rapidly, reliably, stably and continuously detecting gas concentrations 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 devices to remind on-site staff to take necessary protective measures, preventing gas-induced combustion accidents. Working Principle of Gas Detector: The detector installed on-site operates on power supply. When a gas leak occurs, the sensor converts the detected leakage amount into a corresponding voltage signal. After the voltage signal is processed by the detector, data is uploaded and displayed on the screen. When the concentration reaches the set action value, the detector triggers an alarm and drives external devices. A gas detector 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 detector adopts a diffusion method to real-time convert the gas concentration signal at the monitoring point into an electrical signal. After this 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 out. 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 for equipment in industrial sites. Features Clever structural design, extremely easy installation; Upper and lower limit alarm points can be set arbitrarily within the full range; Flameproof design, suitable for hazardous locations in Division 1 and Division 2 of 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 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 dry contact outputs, used for controlling contactors for fans or solenoid valves; Exquisite power supply design, using pure SMT component surface mount technology, ensuring stable product performance; The sensor uses 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-poison 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 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;
