Giriş Gas alarm 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 alarm, the alarm will sound and drive external equipment to remind on-site staff to take necessary protective measures, which can prevent the occurrence of gas-induced combustion accidents. Working principle of gas alarm: The alarm installed on site works with power supply. When gas leaks, the sensor converts the detected leakage amount into a corresponding voltage signal for output. After the voltage signal is processed by the alarm, the data is uploaded and displayed on the screen. When the concentration reaches the set action value, the alarm will sound and drive external equipment. Gas alarm is a fixed instrument that can continuously detect oxygen concentration or toxic, harmful, flammable and explosive gas concentration in the working environment. Gas alarm adopts diffusion method, which converts the gas concentration signal at the monitoring point into electrical signal in real time. The signal is amplified, then processed by 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. Gas alarm adopts dual-chamber design, special imported sensor, and the sensor adopts modular design, which makes calibration and verification more convenient, with superior performance, high stability, multiple signal outputs, convenient installation and maintenance, meeting the requirements of industrial sites for high reliability of equipment. Özellikler Ingenious structural design, extremely simple installation; Upper and lower alarm points can be set arbitrarily within the full range; Flameproof design, can be used in dangerous areas 1 and 2 of factory conditions Gas alarm can be equipped with liquid crystal concentration display, which displays the concentration on site in real time Gas alarm can be equipped with special flameproof acoustic-optic alarm to realize on-site acoustic-optic 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 AC contactor of fan or solenoid valve Ingenious 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 work, small body, convenient operation and good anti-poisoning performance The alarm point adjustment, zero adjustment and target point calibration of the transmitter can be carried out without opening the cover through the controller 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 upper computer
