Introduction A gas detector is a flameproof safety device capable of rapidly, reliably, and stably continuously detecting 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, preventing 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 leakage into a corresponding voltage signal 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 triggers an alarm and drives external equipment. 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 convert the gas concentration signal at the monitoring point into an electrical signal in real time. 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 issued. The gas detector adopts a dual-chamber design, uses special imported sensors, and the sensors adopt a modular design, making 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, suitable for hazardous areas 1 and 2 in factory conditions The gas detector can be optionally equipped with a liquid crystal concentration display, showing the concentration in real time on-site The gas detector can be optionally equipped with a special flameproof acoustic-optic alarm to achieve 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 for controlling contactors of fans or solenoid valves Exquisite power supply design, pure SMT component patch process, ensuring stable product performance; The sensor uses imported gas-sensitive components, with high precision, long service life, small zero drift, fast response time, can work continuously for a long time, has a small body, is easy to operate, and has good anti-poisoning performance The alarm point adjustment, zero point 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 host computer
