How do hydrogen sensor detect hydrogen leaks
What Is a Hydrogen Sensor?
A hydrogen sensor is a device that can detect the presence of hydrogen. Because hydrogen is naturally present in so little of the atmosphere, these sensors measure only what might be considered dangerous. Gas detectors used to monitor hydrogen usually detect gas leaks in closed systems. JXCT hydrogen sensor is cost-effective, high sensitivity, rapid response, a variety of models for users to choose, hydrogen sensor is the first choice.
Hydrogen sensors support a variety of output modes to meet different environmental requirements. Sensor without wiring, low energy consumption, stable performance. Hydrogen sensor can be used with multiple screens, intuitive data display. Hydrogen sensor support audible and visual alarm function, support multiple sensor connection, can achieve linkage control fan, water valve, electric pump.
Matters needing attention:
Regardless of the method used, the leak detection system should automatically shut down the hydrogen source when hydrogen is detected. For systems designed to monitor hydrogen concentrations in a room or area, leak detection systems must inform the user by visual and auditory alarms when the environment becomes hazardous.
The number and distribution of detector placement points and the time required to shut off hydrogen should be based on factors such as leakage rate, ventilation rate and volume of the space being monitored. Sites we need to consider include:
- Permanent installation in indoor storage facilities.
- Key locations where leakage may occur during experiments or process operations involving hydrogen.
- Areas where hydrogen may accumulate.
We establish performance standards for regional hydrogen leak detection systems for the specific applications intended.
Parameter values to be considered include:
- The accuracy of the detector should be 0.25% (by volume) throughout the sensor measurement range.
- For area monitors: response time of 10-30 seconds at 1% concentration (by volume); For sensors deployed in. Housing: 1 second response time at 1% concentration (by volume).
- The minimum range of the sensor should be 0 to 4 vol%, and the detection lower limit should be 0.4 vol%. However, it is recommended that the sensor range be 0 to 10 vol%, and the detection lower limit be 0.1vol%.
Hydrogen leak detection systems must be designed to ensure that any leaking hydrogen passes through the detector. When we test hydrogen, we need to inform the user of their sensitivity to other gases and vapors.
