Core System Capabilities
Rugged ExdIICT6 Certified Enclosure
Safety and structural durability are prioritized with a custom die-cast aluminum housing. This robust casing features an IP66 rating, providing excellent resistance against water splashes and dust ingress. Furthermore, it carries a strict ExdIICT6 explosion-proof certification, making it ideal for volatile and highly combustible industrial atmospheres.
Advanced Laser Scattering Technology
At the core of the detector is an industrial-grade precision sensor utilizing a diffused inlet for immediate and sensitive detection. Real-time concentration values are clearly presented on a 2.5-inch color LCD screen, which is designed to eliminate ghosting and ensure perfect readability under various lighting conditions.
Seamless PLC/DCS Integration
This device offers highly flexible connectivity to fit your existing infrastructure seamlessly. Standard data outputs include a 4-20mA analog signal and an RS485 digital interface utilizing the Modbus RTU protocol. Additionally, it incorporates a built-in relay switch output that can automatically trigger external exhaust fans or emergency shut-off valves.
Integrated Visual and Audible Alerts
To immediately alert personnel of dangerous particulate levels, the system features a highly responsive dual sound and light alarm mechanism. These standard two-level alarms utilize high-decibel audio alongside bright flashing LEDs to guarantee immediate situational awareness, keeping your workforce safe without relying on tactile feedback.
Versatile Deployment Options
The HNAG1000-PM easily adapts to numerous demanding industrial applications, including pharmaceutical workshops, coal processing plants, thermal power stations, and petrochemical facilities. Your engineering team can choose from multiple versatile mounting options—such as wall, pipe, ceiling, or bracket installations—ensuring optimal sensor placement anywhere on site.
