Introduction A gas detector is a flameproof safety device that can quickly, reliably, and stably continuously detect gas concentrations 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 the 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 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 to real-time convert the gas concentration signal at the monitoring point into an electrical signal. After the signal is amplified, it is sampled by the CPU via AD, temperature-compensated, and intelligently calculated, then the measurement result is processed. If the measured value exceeds the set alarm concentration value, an alarm signal will be sent. The gas detector adopts a dual-chamber design, uses special imported sensors, and the sensors adopt a modular design, which is more convenient for calibration and verification. It has superior performance, high stability, can output multiple sets of signals, and is convenient for installation and maintenance, meeting the high reliability requirements of industrial on-site equipment. Features Clever 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 under factory conditions; The gas detector can be optionally equipped with a liquid crystal concentration display to show the concentration on-site in real time; The gas detector can be optionally equipped with a special explosion-proof audible and visual alarm to realize on-site audible and visual 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 to control the AC 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 body, convenient operation, and good anti-poison 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 include 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; |
