A detection unit series with excellent functionality and performance, supporting HART communication features and certified for functional safety standard SIL2!
The "SD-1 Series" is a compact and lightweight smart-type gas detection unit that is particularly suitable for safety and disaster prevention in oil refining and petrochemical plants. With its robust housing structure and various options, it is designed for outdoor installation and can withstand harsh environments. By connecting to alarm units installed in safety locations and higher-level systems in central monitoring rooms or instrument rooms, it contributes to the establishment of a comprehensive disaster prevention system. Additionally, it offers a wide range of options for combustible gases, toxic gases (hydrogen sulfide/carbon monoxide), and oxygen. 【Features】 ■ Compact and lightweight smart type suitable for safety and disaster prevention ■ Extensive lineup ■ Robust housing structure and various options ■ Designed for outdoor installation and harsh environments *For more details, please refer to the PDF document or feel free to contact us.

basic information
**Features** - Hydrogen and acetylene explosion-proof compliant - Can be used as an explosion-proof product even in hydrogen and acetylene environments due to its pressure-resistant explosion-proof structure. - Waterproof and dustproof structure - Can be installed in harsh environments with a protection rating equivalent to IP65. - Compatible with HART communication - Can superimpose digital signals on standard analog 4-20mA outputs, allowing for the exchange of more information. - Equipped with self-diagnosis function - During power supply, it performs "self-diagnosis" simultaneously with warm-up. If an anomaly is detected, the gas concentration value will not be displayed, and instead, the possible cause of the trouble (error code) will be shown. - Also compatible with suction type - By attaching a suction cap (with gas flow path inlet) for the SD-1 series to the main sensor unit, it can also accommodate suction type. - *Note: For use in suction type, a separate suction pump or aspirator unit and its power supply are required.* *For more details, please refer to the PDF document or feel free to contact us.*
