Introduction A gas detector is a flameproof safety device capable of rapidly, reliably, and stably 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, 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 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 diffusion method to convert the gas concentration signal at the monitoring point into an electrical signal in real time. After the 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 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 installation; Upper and lower limit 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, which shows the concentration on-site in real time 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 AC contactors of fans or solenoid valves Exquisite power supply design, pure SMT component surface mount technology, ensuring stable product performance; The sensor uses imported gas-sensitive elements, with high precision, long service life, low zero drift, fast response time, long-term continuous operation, small size, convenient operation, and good anti-poisoning performance The alarm point adjustment, zero point adjustment and target point calibration of the transmitter can be performed without opening the cover through the controller Suitable for the detection of dozens of gases, and can display the gas name; gas units include ppm, LEL%, VOL%, mg/m3 The international standard (4～20)mA signal can be directly connected to the factory DCS system, and the RS485 digital signal is connected to the factory upper computer |
