Introduction A gas detector is a flameproof safety device that can quickly, 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 send 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 is powered on and operates. When a gas leak 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 send an alarm and drive external equipment. A gas detector is a fixed instrument that can continuously detect the concentration of oxygen or toxic, harmful, flammable and explosive gases in the working environment. The gas detector adopts a diffusion method, which in real time converts 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. The gas detector adopts a dual-chamber design and special imported sensors. Moreover, 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 site equipment. Features Ingenious 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 areas 1 and 2 of 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 Meet any range and all gas detection requirements of customers between 1-99999; Two sets of normally open passive contact outputs, used to control the 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-poison 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 the gas name; gas units 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 upper computer
