Advanced Intelligent Sensing and Operational Performance
At the heart of the HNAG1000 is an intelligent sensor array utilizing intrinsic safety technology. This design allows for the simultaneous detection of up to four gases, including flammable, toxic, and harmful gases. Key operational advantages include:
• Tool-Free Maintenance: Users can perform sensor interchangeability, offline calibration, and zero-point self-calibration without the need for specialized tools.
• Intelligent Compensation: The built-in temperature and zero-point compensation algorithm minimizes cross-interference, ensuring high gas selectivity and measurement precision.
• Single-Person Operation: Integrated with remote controller compatibility, operators can manage alarm settings, zero adjustments, and target point calibrations without opening the enclosure.
• Comprehensive Protection: The device features over-range and reverse polarity protection to prevent hazards caused by improper manual handling.
The HNAG1000 features a built-in LTE Cat-1 DTU wireless module that enables real-time data transmission to computers, mobile terminals, PLC, or DCS systems. This ensures that when a danger is detected, alarm notifications are sent instantly to all on-site operators via a synchronized audible and visual alarm system.
