Gas Leak Detector is used in many industrial processes to manufacture and store energy. However, hydrogen also presents a higher explosion hazard than other liquid and gas fuels. This means it is important to ensure that the proper safety measures are put in place when using hydrogen. This includes having reliable and accurate hydrogen detectors to quickly detect leaks.
A hydrogen detector is an electronic instrument that consists of a semiconductor sensor to monitor the presence of hydrogen gas in the atmosphere. The sensor changes its conductivity when exposed to hydrogen, which can be detected by a simple circuit. The resulting output signal is proportional to the concentration of hydrogen in the air, and it can be used to trigger an alarm or other device.
Hydrogen Gas Monitoring: Best Practices for Implementing Hydrogen Detectors
There are several types of sensors that can be used in a hydrogen detection system. Some are designed to be used as a standalone device, while others are part of an integrated hydrogen monitoring system. These systems are typically used in conjunction with visual indicators and other auxiliary devices.
The best hydrogen detection sensor depends on the specific application and environmental conditions. These can include factors such as the operating range, optimized sensitivity, stability and reliability, and the ability to function in wet conditions.
In refinery applications, a handheld hydrogen detector is often used to monitor the area for dangerous leaks. This can include confined spaces such as battery rooms and power generator areas, where a small leak could lead to explosions or asphyxiation. Fixed wall-mounted hydrogen detectors are also available to provide continuous protection. These are especially useful in applications such as hydrocracking, which reduces heavy oil to lower molecular weight constituents. The resulting hydrogen is then used in ammonia synthesis, which produces nitrogen-based fertilizers.
