2014-09-03· Non-dispersive infrared (NDIR) sensors are increasingly being used in multi-sensor instruments to measure LEL combustible gas. But remember, no single type of sensor can detect all types of dangerous gases and vapors. Manufacturers offer different types of sensors to measure combustible gas and VOC vapors. Non-dispersive infrared (NDIR) sensors measure gas as a …
The NDIR gas sensor needs an infrared source for the excitation of the gas molecules. Thermal radiators such as ILT's Visible/IR lamps are often employed for this task. Their operating temperature should be as high as possible to obtain a large output intensity and detector signal. Glass envelope lamps operate at higher filament temperatures when compared to other filament or ceramic heating ...

2015-04-01· In more recent years, non-dispersive infrared (NDIR) sensors have emerged as an alternative for the aging catalytic bead technology. Infrared sensors consist of a gas cell through which infrared...
The AK9700AE is an infrared light emitting element (IR-LED) with a peak emission wavelength in the infrared absorption band of CO2. Compared with the W filament bulb used in the conventional NDIR type CO2 sensor, it can control the light emission at high speed and can also reduce the current consumption of the CO2 sensor dramatically by combining with an AKM infrared light receiving element ...
2019-06-19· NDIR technologies are very popular in gas sensors as many common gases, absorb light very strongly in the infrared region of the electromagnetic spectrum. This means that using a coupled IR source and detector, it is possible to measure even low concentrations of these gases with real-time online monitoring. MIPEX optical gas sensor technology.
On the other hand, LED is another option for an infrared source. LEDs are able to reduce the size and power consumption of whole sensor, but infrared output is rather small and wavelength range is limited. So two LEDs are required when it is used for dual-wavelength method NDIR sensors.
2019-06-19· MIPEX has developed the world’s lowest power non-dispersive infrared (NDIR) gas sensor for highly sensitive, reliable detection of gases such as methane and carbon dioxide. By making use of IR LED sources and new sensor technologies, MIPEX has been able to create robust, non-serviceable gas sensors that can easily be used by OEMs for easy incorporation into gas detector devices that simply ...
On the other hand, LED is another option for an infrared source. LEDs are able to reduce the size and power consumption of whole sensor, but infrared output is rather small and wavelength range is limited. So two LEDs are required when it is used for dual-wavelength method NDIR sensors. Since incandescent lamps and LEDs have different features, it is necessary to select an infrared …
