PHOTOELECTRIC SMOKE SENSOR |
摘要 |
FIELD: physics.SUBSTANCE: claimed sensor comprises light-emitting element arranged in the case to face the detection area and to output the control light thereto. Light-receiving element is arranged outside the control light optical path of light-emitting element to face the detection area. It detects the smoke by reception of dissipated control light that gets into smoke to be dissipated thereon. Reflecting element is arranged inside said case to reflect said control light output from light-emitting element onto light-receiving element so that control light does not penetrate into light-receiving element.EFFECT: higher accuracy of smoke detection.5 cl, 11 dwg |
