摘要：A flame detector arranged to detect flames includes a non- microphonic infra-red sensor having a broad band frequency response. To maximize the sensitivity to radiation from flames in the 4.3 &mgr;m solar absorption band a narrow band optical interference filer, transmissive in the band ...
Flame Imaging Using Infrared And Optical SensorAbd Rahim Muhammad Nur Zulfadhli
PURPOSE:To prevent the lowering of the sensitivity as sensor while achieving compactization, by combining a center electrode in which a small precious metal piece is baked at one cylinder port of a cylindrical insulator so as to be integral with the insulator and an electric heater added to ...
A flame sensor for a furnace of a heating, ventilation, and air conditioning (HVAC) system includes a sensor body and an electrically conductive member of the sensor body. The electrically conductive member is configured to be disposed within a flame region of a burner of the furnace and ...
PROBLEM TO BE SOLVED: To provide a flame sensor, a flame detector and a combustion apparatus with which stable properties with respect to the detection of light emitted from flame can be ensured when a photosensor such as a photo IC or a semiconductor element is used instead of a CdS ...
An optical flame-sensor includes an optical circulator, an optical-fiber cavity, and a first optical sensor. The optical circulator includes a first port, a second port, and a third port. The first port is configured to receive an optical signal. The second port is configured to output the...
