STREULICHT-RAUCHMELDER

An opto-electronic structure measures first (SB) and second (SF) scattered signals at forward and backward angles of dispersion. Evaluatory electronics (12) determine an alarm value by relying on a difference in the scattered signals processed in advance. Their difference is handled with an applicat...

Zusammenfassung:	An opto-electronic structure measures first (SB) and second (SF) scattered signals at forward and backward angles of dispersion. Evaluatory electronics (12) determine an alarm value by relying on a difference in the scattered signals processed in advance. Their difference is handled with an application factor.
