ULTRAVIOLET FLAME SENSOR WITH DYNAMIC EXCITATION VOLTAGE GENERATION

A controller unit for controlling an ultraviolet (UV) sensor may be excited by an excitation voltage that enables the UV sensor to detect incoming UV light. The UV sensor may provide UV detection events that may be related to the intensity of the incoming UV light. The control unit may include an ex...

Beschreibung
Zusammenfassung:	A controller unit for controlling an ultraviolet (UV) sensor may be excited by an excitation voltage that enables the UV sensor to detect incoming UV light. The UV sensor may provide UV detection events that may be related to the intensity of the incoming UV light. The control unit may include an excitation voltage generator, an event detector, and a controller configured to cause the excitation voltage generator to produce an excitation voltage for a cumulative excitation time that is less than 50% of the time, which may significantly increase the operational lifetime and/or reliability of a UV sensor.
