4 results about "Infrared gas analyzer" patented technology

An infrared gas analyzer measures trace gases by determining the absorption of an emitted infrared light source through a certain air sample. Trace gases found in the Earth's atmosphere get excited under specific wavelengths found in the infrared range. The concept behind the technology can be understood as testing how much of the light is absorbed by the air. Different molecules in the air absorb different frequencies of light. Air with lots of a certain gas will absorb more of a certain frequency, allowing the sensor to report a high concentration of the corresponding molecule.

Detector for infrared gas analyzer

ActiveJP7865444B1Transmissivity measurementsEngineeringInfrared transmission
To improve work efficiency during manufacturing and maintain good sensitivity over the long term. [Solution] The infrared gas analyzer detector (20) comprises first to third infrared transmitting windows (21 to 23) that transmit infrared rays, a front gas chamber forming body (27) to which the infrared transmitting windows are joined to form first and second gas chambers (31, 32), and a sensor unit (60) housed in a containment space (62) communicating with each gas chamber to detect the concentration of the gas to be measured. The gas chamber forming body comprises a frame (81 to 83) to which the first to third infrared transmitting windows are joined, and a main body (34) that forms each gas chamber and to which the first to third frame (34) is joined. The infrared transmitting windows and the frame are joined at room temperature via metal layers (86, 88) formed in the joining regions of each.

An infrared gas analyzer

This utility model relates to the field of gas analyzer technology, specifically to an infrared gas analyzer, comprising: a housing, a detection component, and a heat insulation component; the detection component is placed in the inner cavity of the housing and is used to detect gas concentration; the heat insulation component is connected to the housing, and a mounting cavity is formed between the heat insulation component and the housing, with the detection component located within the mounting cavity. This utility model, by installing the heat insulation component on the housing, forming a mounting cavity between the heat insulation component and the housing for mounting the detection component, and placing the detection component within the mounting cavity, prevents the detection component from directly contacting the external environment, thereby isolating the detection component from interference from external ambient temperature, and thus avoiding the influence of ambient temperature changes on the output intensity of infrared light, improving measurement accuracy.

Detector for infrared gas analyzer

ActiveJP7865412B1Transmissivity measurementsInfrared transmissionMaterials science
To improve work efficiency during manufacturing and maintain good sensitivity over the long term. [Solution] The infrared gas analyzer detector (20) comprises first to fourth infrared transmitting windows (21 to 24) that transmit infrared rays, a front gas chamber forming body (27) and a rear gas chamber forming body (28) to which the infrared transmitting windows are joined to form first to third gas chambers (31, 32, 49), and a sensor unit (60) housed in a containment space (62) communicating with each gas chamber to detect the concentration of the gas to be measured. The gas chamber forming body comprises a frame (35a to 35c, 52) to which the first to fourth infrared transmitting windows are joined, and a main body (34, 51) that forms each gas chamber and to which the first to fourth frame (34 to 51) is joined. Each infrared transmitting window is joined to the frame via a joining member (45 to 48) which is made of low melting point glass.
