The range of an IR flame detector is a critical factor determining its effectiveness in safeguarding industrial facilities. At Shanghai Gewei Electronic Safety Equipment Co., Ltd., we specialize in advanced flame detection solutions that deliver exceptional detection distances while ensuring precision and reliability. Our IR flame detectors utilize cutting-edge UV/IR multi-spectral technology combined with AI-driven algorithms to detect flames at distances exceeding 60 meters under optimal conditions, making them ideal for high-risk environments like oil refineries, chemical plants, and power generation facilities.
Detection range primarily depends on three key factors: sensor sensitivity, environmental conditions, and flame characteristics. Our flagship GW820IR4 model, engineered for harsh industrial settings, achieves an axial detection distance of over 60 meters—the longest in our product lineup. This is enabled by its 32-bit high-precision processing chip paired with imported low-noise infrared pyroelectric sensors, which identify specific radiation signatures of flames while filtering out false triggers from sunlight, welding sparks, or hot machinery. The detector’s wide 110° detection angle further enhances coverage, ensuring comprehensive monitoring of expansive areas without blind spots.
Environmental variables like humidity, dust, and smoke can influence detection performance. To address this, our detectors incorporate lens contamination monitoring and adaptive sensitivity adjustments. For instance, the GW800IR2 model automatically compensates for reduced visibility in dusty atmospheres, maintaining reliable detection at its 50-meter range. This resilience is crucial for facilities where combustible dust or chemical vapors are present, as it minimizes the risk of undetected fires that could escalate rapidly.
Shanghai Gewei’s commitment to innovation is reflected in our proprietary multi-spectral fusion technology. Unlike single-spectrum detectors, our solutions cross-reference UV and IR signals to eliminate false alarms. For example, the GW300UVIR3 model combines UV and IR sensors to verify genuine flames before triggering alerts, reducing nuisance activations by over 90%. This technology not only extends the effective detection range but also ensures compliance with stringent safety standards like SIL2/SIL3 and Ex d IIC T6 Gb certifications.
For applications requiring even greater coverage, our GW810IR3 detector offers a 50-meter range with dual UV/IR sensors, making it suitable for large infrastructure like tunnels and military installations. Its IP67-rated housing and -40°C to 70°C operational temperature range guarantee performance in extreme environments, while 4-20mA current outputs enable seamless integration with IoT-based fire suppression systems. This aligns with our broader portfolio of gas detectors and cloud platforms, providing end-to-end safety ecosystems.
Beyond range, our detectors prioritize response speed. The GW100UVIR2 model triggers alerts in under 3 seconds for high-priority threats, enabling rapid activation of suppression systems. This speed, combined with robust construction—engineered with corrosion-resistant cast aluminum housings and vibration-resistant mounts—ensures longevity in demanding industrial settings. Maintenance is minimized through self-diagnostics and modular sensor designs, reducing downtime and operational costs.
In summary, the detection range of our IR flame detectors spans from 30 meters to over 60 meters, tailored to specific industrial risks. Shanghai Gewei’s relentless focus on technological excellence ensures that our products not only meet but exceed industry expectations for reliability, accuracy, and adaptability. By integrating AI with multi-spectral sensing, we deliver solutions that protect lives and assets while minimizing false alarms—a testament to our mission as pioneers in electronic safety equipment.
