Fixed gas sensors are used to detect the presence of hazardous gases in a variety of settings, including:
- Medical and industrial facilities.
- Commercial buildings.
- Swimming pools.
- Saunas.
- Academic facilities.
The sensors in these fixed systems operate continuously and will trigger an alarm when the concentration of certain gases reaches a dangerous level.
The placing of these sensors is critical to the overall effectiveness of the gas detection system. The sensors must be placed in locations where they are most likely to detect a gas leak without too much interference from their local environment.
Factors to consider when positioning fixed gas sensors:
The type of gas being detected:
The density of the gas will affect how it disperses in the air. Heavier gases, such as propane and methane, will sink to the ground, while lighter gases, such as hydrogen and helium, will rise. Also, the sensors should be placed at a height that will allow them to detect the gas at its highest level of concentration.
The location of the gas source:
If the gas source is known, the sensors should be placed as close to the source as possible. This will help ensure the sensors detect the gas leak as quickly as possible.
The ventilation system:
If the area is well-ventilated, the gas will disperse more quickly so sensors will need to be placed closer together than that of a similar area with poor ventilation.
The physical environment:
The sensors should be placed in areas where they are not likely to be damaged by dust, dirt, or water. They should also be placed in areas where they will not be obstructed by objects.
The accessibility of the sensors:
The sensors should be placed in locations where they can be safely accessed by engineers for maintenance and calibration.
Place sensors in areas where people are likely to be present:
This includes walkways, doorways, and other areas where people are likely to come into contact with a gas leak.
Place Fixed Gas Sensors in areas where there is a risk of gas accumulation:
Such as a confined space. This includes areas where there are pipes, valves, and other potential gas leak sources.
Place sensors in areas where there is poor ventilation:
This will help to ensure that the sensors detect the gas even if it is not well-dispersed.
Avoid placing sensors in areas where they are likely to be damaged by heat, cold, or moisture.
Regularly inspect the sensors to ensure that they are in good working order.
