Flame monitoring device with voltage generator and voltage measuring device; Method for operation of the device

摘要

The device has a voltage generating and measuring device (10) with a voltage generating unit (12) to generate an ignition voltage to operate an ignition device (14) of a burner (22) and/or an ionization voltage for an ionization electrode (16) to monitor a flame of the burner. A measuring unit (20) measures an ionization current generated by the ionization voltage. A control unit (24) controls the unit (12), and evaluates a measured value of the unit (20). The unit (24) determines dynamic feedbacks (30a, 30b) of the device (10), and identifies a malfunction of elements of the device (10). An independent claim is also included for a method for monitoring a burner by a flame monitoring device.
