Atex Explosion Proof Fixed Hydrogen Sulfide H2s Gas Detector Monitor System
The YA-D400 series point type gas detectors are essential devices extensively employed in hazardous settings, including chemical plants, petroleum industries, metallurgical sites, stations for liquefied gases, gas transmission, and distribution systems, painting operations, and other indoor and outdoor environments that pose threats due to possible gas leakages that can lead to fatal outcomes.
Our company has launched an efficient and straightforward gas detection tool, the YA-D400 series point type gas detector. It can be combined with our YA-K series gas alarm controller to build an industrial gas alarm system. Available in wall-mounted installation, it can also sustain tube type, scaffolding type, ceiling type installations as required.
The product's functionality encompasses processing the gas detector's data, enabling various data processing options through the controller's single chip microcomputer, leading to the accomplishment of data display, and output control activities.
YA-K300 series gas alarm controllers can be seamlessly integrated with our YA-D series gas detectors to manifest industrial gas control systems. This product accommodates detection and early warning systems exclusively developed for the industrial environment. It has a 4.3-inch industrial LCD display mode that succinctly portrays the measured gas concentration level with an overtly visible display.
If the gas concentration exceeds the threshold limit, an audio-visual alarm goes off instantaneously. Furthermore, it is invigorated with multiple output relays that can drive fan exhausts, solenoid valves, and other devices in either active or passive modes, adapting to different field-specific scenarios and demands.
It encompasses several advantages of being fast in response speed, reliable, with minimal failure rates, and easy to maintain. The system ensures safety in circumstances of unforeseen alarming failures, where multiple event delay confirmation aids in averting false alarms, safeguard life and property from possible dangers.
The product has wall-mounted installation capabilities and, through the collaboration with the detector and controller's intelligent microcomputer, the data acquired can undergo numerous processing procedures, culminating in data display, output control and other essential functionalities.
The D400 Gas Detector is a highly functional device that is perfect for keeping track of any detected gas concentrations. The device comes with several features that make it reliable and efficient for any gas-related work. Some of the features include:
The K300 Gas Alarm Controller is a microprocessor-embedded device that comes with a variety of software functions, making it highly intelligent and efficient. It has complete detector signal sampling, data real-time calculation, system fault detection, power management, key scanning, display driver, alarm display, alarm peripheral driver, and other functions. Some of the features of the K300 Gas Alarm Controller include:
