Abstract

Improvements to a disturbance-safe surveillance installation to monitor the presence of a burner flame, with adjustable sensitivity and adjustable response times which, on the input side, contain a pulse-like signal, which comes from one or more detectors, they are exposed to flame radiation and preferably contain ionization tubes and on the outlet side it yields emitting a flame presence signal, safe against disturbance, characterized in that the installation is made up of a main chain connection, individually graded disturbance locks, the first degree of which, on the input side, contains the signal, as a pulse, if necessary, but not necessarily modulated by a mechanical shutter, in which the main chain connection is established in such a way that, for the generation of the useful signal, at the output of the main chain connection, the presence of the respective signal is unavoidable to the tool at the entrance of each degree, because each degree of the main chain connection is a degree, which works cyclically-dynamically, in which each construction element of the degree, under the action of an electrical check signal, periodically alternating, which does not necessarily have to be the same test signal for all the existing grades, it can continuously and periodically go through all the points of a working curve of the construction element and why each degree is established in such a way, that the useful signal, at the exit of the respective grade is omitted, provided that at least one element of construction, unavoidably required for, the safety of disturbance, at least for a duration of the period, does not continuously go through all the points of its working curve.
