FIELD: alarm system.
SUBSTANCE: using for automatic signaling of the presence of high-temperature corrosive environment. Gist of the invention consists in the fact that an ionization sensor signaling the presence of high-temperature corrosive environment contains a means of fixing on the body of a test object, central insulated metal electrode with contacts for connection to an alternating current source, the electrode is covered with an oxide film with thickness that provides an ionization current of at least 200 mcA.
EFFECT: ensuring the stability of an alarm system.
