In today’s complex industrial landscape, where volatile materials and high-energy processes are commonplace, the specter of fire and explosion looms large. Ensuring functional safety is not merely a regulatory requirement; it is a moral imperative to protect human lives, preserve critical assets, and maintain operational continuity. At the forefront of this mission are highly reliable flame detection systems. However, not all detectors are created equal. The distinction lies in their Safety Integrity Level (SIL) certification, with SIL 2 and SIL 3 representing the pinnacle of safety performance. These certifications are crucial for industries where the consequences of a missed fire event are catastrophic.
Understanding Safety Integrity Levels (SIL) for Flame Detection
Safety Integrity Level (SIL) is a quantitative measure of the reliability and risk reduction provided by a safety instrumented function (SIF). It’s defined by international standards like IEC 61508 and IEC 61511. A higher SIL rating signifies a greater degree of confidence that a safety system will perform its intended function under specified conditions. For flame detectors, this means the probability of failure on demand (PFD) is extremely low. SIL 2 certification implies a PFD between 10-2 to 10-3, while SIL 3 demands an even stricter PFD between 10-3 to 10-4. In environments handling hydrocarbons, chemicals, or other flammable substances, specifying SIL-certified flame detectors is non-negotiable. It ensures that the detection system itself is inherently designed, manufactured, and tested to an exacting standard, drastically reducing the chance of undetected hazards.
GEWEE’s Unwavering Commitment to Advanced Safety
At Shanghai Gewei Electronic Safety Equipment Co., Ltd. (GEWEE), we deeply understand the critical nature of functional safety in hazardous environments. We are dedicated to providing cutting-edge solutions that exceed industry standards, ensuring peace of mind for our clients worldwide. Our core product offerings include state-of-the-art flame detection equipment, highly sensitive gas detection equipment, and comprehensive advanced IoT systems coupled with intuitive cloud platforms for integrated safety management. We don’t just sell detectors; we deliver holistic safety ecosystems designed for the future.
Pioneering Technology in Flame Detection
Our flame detection equipment leverages advanced UV/IR and multi-spectral technologies, fortified with sophisticated AI analysis. This powerful combination allows our detectors to precisely identify the unique signatures of flames while intelligently discriminating against false alarms from common industrial disturbances like hot objects, welding arcs, or sunlight. This unparalleled accuracy is powered by high-precision 32-bit data processing chips and imported low-noise photodetectors, guaranteeing rapid and reliable response times. Furthermore, our advanced algorithms are meticulously developed to not only detect but also to eliminate false positives, a common challenge in less sophisticated systems.
Our Portfolio of SIL 2/SIL 3 Certified Flame Detectors
GEWEE offers a diverse range of flame detectors, each engineered to meet the specific demands of various industrial environments. Many of our flagship models proudly carry SIL 2 and SIL 3 certifications, underpinning our commitment to the highest safety standards.
The Versatile GW100 Series
The GW100 series exemplifies robust and reliable flame detection for a wide array of applications. The GW100UV, for instance, stands out with its SIL2 and SIL3 (UV) certifications, making it ideal for environments requiring stringent safety. It features a 32-bit high-precision data processing chip, coupled with an imported low-noise UV photoelectric sensor and a self-developed infrared pyroelectric sensor. This model boasts multiple sensitivity levels, wide detection angles (UV ≥120°, IR ≥100°), and an impressive axial detection distance exceeding 40 meters. Its advanced algorithms ensure precise flame detection while minimizing false alarms. With CCC and explosion-proof certifications (Ex d IIC T6 Gb), and an IP66/IP67 (UV) protection rating, the GW100UV is designed for industrial plants, offering reliable performance with low maintenance costs. Other variants like the GW100IR2N are perfect for mechanical equipment and smaller spaces, while the GW100IR3 and GW100UVIR2 provide robust UV/IR detection for general industrial facilities, all built with similar core technologies and high protection ratings.
High-Performance GW800, GW810, and GW820 Series
For the most challenging and critical industrial applications, our GW800, GW810, and GW820 series set the benchmark for performance and safety. These advanced flame detectors are all SIL2 and SIL3 certified, providing an unmatched level of functional safety. They feature 32-bit high-speed, low-power, high-performance data processing chips paired with imported low-noise IR pyroelectric sensors and UV photovoltaic sensors. A key innovation in these series is their ability to detect lens contamination, ensuring continuous optimal performance even in dusty or harsh conditions. With detection angles greater than 110° (IR) and 120° (UV), and axial detection distances stretching beyond 50 meters for the GW800/GW810 series and exceeding 60 meters for the GW820 series, these detectors offer expansive coverage. Models like the GW800IR2, GW810IR3, GW810UVIR2, GW820IR4, and GW820UVIR3 are explosion-proof (Ex d IIC T6 Gb, with some models also certified for dust environments Ex ID A21 IP66/67 T80°C) and boast IP66/IP67 protection. Their robust cast aluminum or optional stainless steel housings make them ideal for extreme environments such as tunnels, petrochemical facilities, military installations, and large-scale industrial plants. They offer versatile outputs including 2 relay outputs and 4-20mA current output for seamless integration into existing safety systems.
