Zusammenfassung:FIELD: aerosol measuring equipment, particularly devices to form charged aerosol stream in pulsed corona discharge in fire alarms of charging-inductive type to be widely used in hospitals, museums, archival depositories, banks, electronic and power facilities, pressure chambers and so on. ^ SUBSTANCE: device comprises gas flue, outer and central electrodes coaxially arranged in the gas flue one after another in stream direction, as well as precipitation electrode. The outer and central electrodes define corona discharge chamber of needle-and-cylinder type. All electrodes are linked to voltage source. Additional electrode is installed downstream of precipitation one along gas flue axis. The additional electrode is also connected to voltage source. ^ EFFECT: increased reliability of fire risk detection. ^ 1 dwg
