Flame detector

<p>A flame detector is a <a href="/facts/Sensor/RN8SXbjs">sensor</a> designed to detect and respond to the presence of a <a href="/facts/Flame/UMNDVEe8">flame</a> or <a href="/facts/Fire/M6XwR3am">fire</a>, allowing flame detection. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a <a href="/facts/Propane/E0b23KGh">propane</a> or a <a href="/facts/Natural_gas/9MYQ7NAP">natural gas</a> line), and activating a fire suppression system. When used in applications such as industrial furnaces, their role is to provide confirmation that the furnace is working properly; it can be used to turn off the ignition system though in many cases they take no direct action beyond notifying the operator or control system. A flame detector can often respond faster and more accurately than a <a href="/facts/Smoke_detector/WX5HPBPV">smoke</a> or <a href="/facts/Heat_detector/qtKllRBf">heat detector</a> due to the mechanisms it uses to detect the flame.
