NA1000D multi-channel hydrogen leakage monitoring system
NA1000D multi-channel hydrogen leakage monitoring system
The NA1000D multi-channel hydrogen leakage monitoring system consists of a NA1000MR multi-channel alarm controller and a NA1000D II hydrogen monitoring transmitter. It is used to monitor the content of hydrogen within the lower limit of hydrogen explosion in hydrogen cooled generator units, and can be equipped with up to 16 transmitters for centralized control of multiple points.
This system adopts high-performance transmitters, which are powered by the monitoring host to convert gas concentration signals into electrical signals and send them to the monitoring host. The large LCD color screen directly displays multiple hydrogen concentration and alarm situations. When the hydrogen concentration reaches the preset alarm value, the system sends an alarm signal to remind early safety measures to ensure safe production.
