介绍 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. Gas alarm working principle: The alarm installed on site operates with power supply. When gas leakage occurs, 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 sounds and drives external equipment. Gas alarm is a fixed instrument that can continuously detect the oxygen concentration in the working environment or the concentration of toxic, harmful, flammable and explosive gases. The gas alarm adopts the diffusion method, and converts the gas concentration signal at the monitoring point into an electrical signal in real time. 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 alarm adopts a dual-chamber design, special imported sensors, and the sensors adopt a modular design, which makes calibration and verification more convenient, 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 sites for equipment. 特点 Clever structural design, extremely simple installation; Arbitrary upper and lower alarm points can be set within the full range; Flameproof design, can be used in hazardous areas 1 and 2 of factory conditions The gas alarm can be optionally equipped with a liquid crystal concentration display, which displays the concentration in real time on site The gas alarm can be optionally equipped with a special flameproof acoustic-optic alarm to realize on-site acoustic-optic alarm Meet customers' any range requirements between 1-99999 and all gas detection needs; Two sets of normally open passive 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 uses imported gas-sensitive elements, 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 without opening the cover through the controller Suitable for dozens of gas detections, and can display the gas name; gas unit names 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
