NA1000MS Fixed Hydrogen Leak Monitoring System
Multi-channel fixed hydrogen concentration monitoring and alarm control for safer hydrogen-cooled equipment and industrial hydrogen applications.
Overview
The NA1000MS is a fixed multi-channel hydrogen leak monitoring system built for centralized hydrogen concentration control and alarm management. It is composed of the NA1000MR multi-channel alarm controller and the NA1000DII hydrogen monitoring transmitter. The system is designed to monitor hydrogen concentration within the lower explosive limit range in hydrogen-cooled generator units and other fixed hydrogen operating points, while displaying real-time readings and alarm status on a large color LCD.
Key Applications
Hydrogen-cooled generators
Generator neutral points
Steam and excitation end oil return systems
Internal cooling water tanks
Hydrogen production and transfer points
Centralized multi-point hydrogen monitoring
Problems It Solves
Monitors hydrogen concentration across multiple fixed points from one central control system
Helps operators detect and respond early when hydrogen concentration approaches preset alarm values
Improves safety oversight in hydrogen-cooled generator units and other fixed hydrogen operating areas
Supports centralized alarm management where portable inspection alone is not enough
Key Features
Built from the NA1000MR multi-channel alarm controller and the NA1000DII hydrogen monitoring transmitter for centralized fixed monitoring
Supports up to 16 transmitters for multi-point hydrogen concentration control and alarm management
Uses a large TFT256 color LCD to display real-time hydrogen concentration and alarm status across multiple channels
Provides dedicated sampling systems for generator neutral points, oil return systems, internal cooling water tanks, and other site-specific points
Uses all-metal explosion-proof transmitter housing with Ex ia IIC T4 Ga protection
Makes maintenance easier because the transmitter design allows replacement of core components during servicing
