Explore our high-performance optical flame detection line. Engineered with advanced UV, dual IR/UV, and Triple IR (3IR) technologies to provide rapid response and superior false alarm immunity.
An authoritative guide to spectral sensing, false alarm prevention, and safety-critical execution protocols in harsh chemical processing and heavy industries.
In high-risk industrial facilities, rapid and reliable fire detection is critical. Conventional heat and smoke detectors are often too slow or impractical for open, outdoor, or highly ventilated process areas. This is where optical flame detection technology becomes essential. By monitoring specific electromagnetic radiation bands emitted during the combustion process, modern flame detectors can identify fires within milliseconds, even over long distances.
Industrial optical flame detectors generally operate across three primary spectral bands:
Selecting the right flame detector manufacturer is a strategic decision that affects both cost-efficiency and safety. China has transitioned from a high-volume manufacturing center to a global leader in high-reliability, technology-driven safety equipment. The primary advantages include:
Procuring flame detectors for hazardous locations requires strict adherence to international safety certifications. Global engineering, procurement, and construction (EPC) companies require safety compliance across several key areas:

Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise", "National Quality Leading Enterprise in the Gas Alarm Industry," member of the China Fire Protection Association, and the main drafting organization for the national standard of solenoid valves, further confirming its industry influence and reputation.
In the field of intellectual property, Xinhaosi has built a robust innovation system with over 50 patents and software copyrights. These patents cover core technological areas, including a graphical monitoring system for gas detection and alarm, which enables predictive maintenance based on historical data to reduce equipment failure rates by over 30%, and a solenoid valve with flow monitoring functionality that integrates flow detection and alarm capabilities. The company also pioneered China's first networked bus-type gas leakage monitoring system and the only maximum-point gas leakage monitoring system certified by the Ministry of Public Security, demonstrating its leading position in cutting-edge technological research.
Our in-house laboratory is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), recognized both domestically and internationally under the ILAC-MRA framework. It operates in accordance with ISO/IEC 17025, the international standard for testing and calibration laboratories. It provides reliable and traceable testing services for gas detection and alarm products, solenoid valves, and related safety equipment. Test reports issued by the CNAS-accredited laboratory are widely accepted by regulatory authorities, certification bodies, and customers in China and overseas, helping to ensure product quality, safety compliance, and market access.
Deploying robust, explosion-proof safety architectures across challenging and hazardous environments.
Highly volatile hydrocarbon processing requires fast 3IR flame detection. Our systems integrate with automated deluge valves and emergency shutdown systems (ESD) to contain fires before they escalate into catastrophic explosions.
Hydrogen burns with a near-invisible flame that does not produce CO2, rendering standard 3IR detectors ineffective. We utilize specialized UV/IR and dual IR sensors optimized for hydrogen's unique spectral signature to protect charging stations and electrolysis units.
Liquefied Natural Gas terminals are vulnerable to cryogenic leaks and flash fires. Our explosion-proof detectors operate in temperatures as low as -40°C, providing continuous monitoring under severe winter conditions.

How advanced sensors, edge computing, and wireless protocols are changing industrial fire safety.
Integrating artificial intelligence into flame detector DSP chips allows for real-time Fourier analysis of flame flicker rates. This helps systems distinguish actual combustion from artificial sources like modulations from reflective surfaces or high-temperature machinery.
Retrofitting legacy plants with wire runs can be cost-prohibitive. Modern facilities are increasingly adopting wireless mesh networks (using protocols like ISA100.11a or WirelessHART) to transmit non-critical alerts and status indicators directly to control centers.
To reduce periodic manual testing in high or hard-to-reach locations, modern detectors feature automated optical self-testing. An internal light source periodically fires through the window to check lens cleanliness and sensor response, confirming path integrity.
