Abstract

Ved en branndetektor for overvåkning av et utstrakt område, spesielt for signalisering av skogbranner, med en opphøyet anordnet, asimut-bevegelig avfølerinnret- ning, er det i en reflektor (6) i dennes brennplan på en bærer (7) anordnet en rekke ved siden av hverandre liggende infrarødømfintlige sensorelement-par (S, S1) som ut fra den optiske akse (A) oppad har en tiltagende utstrekning eller flate og er forbundet med hverandre i en tiltagende uømfintlig kobling. Således dekkes i mottagerfeltene med forskjellig elevasjon et tilnærmet like stort distanseområde, og det oppnås en distanseuav- hengig eller med distansen tiltagende deteksjonsømfint- lighet, slik at også en skogbrann langt borte blir detektert like sikker som en brann i nærheten. For å eliminere feilalarmer, er sensorelementene forbundet i differensielle koblinger parvis ved siden av hverandre på samme bærer (7). For å koble ut feilalarmer ved intesiv solstråling, er det parallelt med de infrarøde sensorelementer anordnet lysomfintlige solceller i en undertrykkelseskobling med disse.
