The FL20BX flame detector consists of a special optical head made of light alloy,
separate from the rest of the electronics (analyzer), and designed for CESI-certified Ex-d explosion-proof operation.
The operating principle is based on the detection of infrared radiation emitted by a flame. The optical head therefore allows for installation in potentially explosive atmospheres and where installation space is limited.
The optical detection head is equipped with two types of IR sensors, each with a different viewing window in the spectral field.
