Title:
火炎用測定装置
Document Type and Number:
Japanese Patent JP4965028
Kind Code:
B2
Abstract:
The measurement device for a flame, is particularly for use in a regulating device for a burner. It has an ionization electrode in the burner flame area, to which alternating voltage is connected and dependent upon the ionization current a direct voltage constituent is superimposed. The alternating voltage constituent influenced by the flame resistance is separable by first devices (5,6) from the direct voltage constituent, with which it is comparable via second devices (9,10) in order to produce a pulse width modulated signal. The two voltage constituents are separable by a high pass and a deep pass. They are comparable by a comparator (9). The direct voltage constituent is comparable with a reference voltage (U REF) in order to be used as a flame signal. The flame signal is applied to a monoflop (11), in order to form a static on/off signal.
