Diligent Micro Controls offers Flame Monitor for Detecting Ions in Gas Flames. Diligent Micro Controls offers Electronic Controllers, Electronic Control Systems & Electronic Control Relays. The Flame Monitor for Detecting Ions in Gas Flames or Diligent Flameye N is designed to detect the flame by picking up ions which are present in the flame. Gas flame, unlike oil flame is blue and is nearly not detectable by conventional sensors like Photo Resistor or Photo Voltaic sensors. Such flame is easily and effectively detected by picking up ions present in it. The only condition for reliable sensing of flame by this is that the flame must be properly set & stable to ensure unbroken path of ionic current.
