IMPROVED FLAME SENSOR AND METHOD OF USING SAME

摘要

A circuit for a flame sensor and a method for sensing the presence of a flame in a burner. The signal from the sensor is passed to an amplifier located adjacent to the sensor and amplified without having a sensor signal contaminated with common mode radiation. The pulsed signal is passed from the amplifier to a rectifier. The pulsed signal of the amplifier is a fully amplified signal.
