Flame sensors help prevent explosions

Accidents involving explosions in industry are more common than you think, but the topic is little discussed in Brazil. Cases like these have serious consequences such as the loss of human lives, material damage and the environment. The lack of protection and negligence of managers, can be pointed to as the main causes of the tragedies that involve explosions and fires. An item that is essential in the control of these events is the presence sensor, used in several types of burners, this equipment can save lives.

The flame presence sensor is part of the safety circuit of industrial furnaces and boilers, your primary function is to indicate the presence of flames in the equipment, if they turn off, the sensor sends an electrical signal to the central controller that operates the fuel valves and that is cut immediately. This action is essential to avoid accidents, since after the extinction, the accumulation of fuel can generate an explosion.

For large burners, usually found in the industry, flame sensors have optical readers which allow the appliance can actually "see" the flame to have control over her. These readers have a photoelectric cell to be exposed to ultraviolet/infrared light generates voltage from it, the more intense the light of the flame, the greater the voltage generated. To avoid any kind of problem, the sensor window must be fully exposed to the flames, any accumulation of dust or other materials can disable generating equipment failures in the process.

Flame sensors with optical readers can be used in gas burners, light or heavy oils, coal, or any other fuel with flames emitting ultraviolet stable. The XS Gas offers a full range of industries sensors ensuring quality and security for their customers.
