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 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 on 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 triggers an alarm and drives 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 to real-time convert the gas concentration signal at the monitoring point into an electrical signal. 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 are modularly designed, 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; Upper and lower alarm points can be set arbitrarily within the full range; Flameproof design, can be used in hazardous areas 1 and 2 of industrial plants; 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 passive contact outputs, used for controlling AC contactors of fans or solenoid valves; Exquisite power supply design, pure SMT component patch process, making the product performance stable; The sensor uses 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-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 gas names; Gas unit names: ppm, LEL%, VOL%, mg/m3; International standard (4～20)mA signal can be directly connected to the industrial DCS system, and RS485 digital signal is connected to the industrial host computer.
