In the recent years, ensuring the safety and reliability
of industrial processes has become an increasingly critical
challenge. The flame detection in pipes remains a crucial area of
concern.We propose an innovative approach utilizing a capacitive
sensor for flame detection in pipes. The sensor harnesses the
electrical properties of flames offering a promising alternative to
traditional detection methods. The design focuses on maximizing
the sensitivity considering parasitic capacitances of the assembly.
Following the trend in the industry towards digitization and
miniaturization, an integrated capacitance to digital converter
is used, combining a superb accuracy and a high sample rate.
The capacitive sensor demonstrates high effectiveness in detecting
flames at a test facility.
