The present invention relates to a device for detecting by measurement a fire-like event (1), in particular a spark,
flame,
ember or
hot particle event, in a reservoir (2) which is loaded with media or through which media flows, the device having a measuring arrangement (4) which is designed to capture measurement data, the measuring arrangement (4) comprising: a first and a second measuring unit (11, 12) for detecting
electromagnetic radiation (5) in a first or second
wavelength range emitted by the fire-like event (1); optionally a third measuring unit (13) for detecting environmental light (7); and optionally a sensor unit (14) for measuring media-specific or environment-specific measurement data. In order to reduce the risk of false alarms in such a device and to improve the identification and
hazard assessment of fire-like events, according to the invention a testing means (8) is provided, which is designed to test, at a
current point in time (tA) on the basis of measurement data captured by the measuring arrangement (4) and / or stored medium-specific or environment-specific characteristic data, whether an
adaptation criterium (A) is met, wherein, if the
adaptation criterium (A) is met, a measuring sensitivity (M1, M2, M3) or an operating parameter (P1, P2, P3) of at least one of the measuring units (11, 12, 13) can be adapted appropriately to the situation using a control means (10). The invention further relates to a method for detecting by measurement fire-like events (1) and to a
system for reliably eliminating a hazardous state caused by a fire-like event as required.
