Product Description
1、Product Introduction
IR-SF6 series diffusive infrared sensor is a gas sensor based on the principle of single light source dual wavelengths using non-dispersive infrared detecting technology(NDIR). The sensor applies a high-end infrared light source and a detector, choosing gold-plated parts as light path return channel, which improve the measuring accuracy and stability. Meanwhile, the environmental suitability of the sensor is also enhanced by adding certain special mature technology.
The major applications of the sensor include electricity, petrochemical, food processing, semiconductor and other industries, which is suitable for leakage alarm, environmental protection, industrial safety and other occasions.
2、Product Features
• Fault diagnosis and false alarm prevention technology
• Temperature and pressure compensation technology
• Anti-condensation technology
• Life span is greater than 10 years
