Intrinsically safe sensors are devices designed to operate safely in hazardous environments, such as those containing flammable gases or dust. They limit the energy output to a level that is too low to ignite any explosive materials, ensuring safety in potentially dangerous situations. These sensors are commonly used in industries like oil and gas, chemical manufacturing, and mining. By adhering to strict safety standards, intrinsically safe sensors help protect workers and equipment while maintaining reliable performance in challenging conditions.
