A hydrogen combustible gas alarm meter is a device used to detect the concentration of hydrogen (H2) in the air. It is based on the flammability of hydrogen, measures the concentration of hydrogen in the indoor air through sensors, and triggers an alarm when a set threshold is exceeded to remind people to take corresponding measures.
Working principle
Hydrogen combustible gas alarms usually use semiconductor sensors or combustible gas sensors to detect the concentration of hydrogen. The sensor chemically reacts with hydrogen or changes the electrical signal, generating an electrical signal. The sensor measures and analyzes the strength of this electrical signal and determines the concentration of hydrogen in the indoor air based on the measurement results. Once the hydrogen concentration exceeds a set threshold, the alarm will issue an alarm signal such as sound, light or vibration.
Application field
Hydrogen combustible gas alarms are widely used in the following fields:
Hydrogen energy industry: It is used to monitor hydrogen leakage in hydrogen energy stations, hydrogen storage facilities, and hydrogen fuel cell vehicles to ensure safe production and use.
Chemical plants and manufacturing industries: used to monitor the concentration of hydrogen in chemical plants, petrochemical plants, dangerous goods warehouses, and other places to ensure the health and safety of workers.
Laboratories and research institutions: used to monitor hydrogen concentrations in laboratories, research institutions, and research sites to ensure safety and accuracy of experimental results.
Hydrogen transportation and storage: Used to monitor leaks in hydrogen transportation and storage systems such as hydrogen pipelines, hydrogen storage tanks, and hydrogen delivery vehicles.
New energy vehicle charging station: It is used to monitor the leakage of hydrogen in hydrogen energy charging stations to ensure the safe operation of the charging station and the safety of the charging process.
General technical parameters
