N.E.T. BLACK BODY TECHNOLOGY DRAMATICALLY EXTENDS THE RANGE OF NDIR-DETECTED GASES

N.E.T. MEMS-based IR source sensors allow Customers to measure the most extensive range of NDIR-detected gases on the market today. N.E.T. extend the emission spectrum of the NDIR sensors using of a state-of-the-art, MEMS-based IR sources featuring true Blackbody radiation characteristics.

This is 'How' and 'Why' N.E.T. use MEMS-based IR sources technology to benefit Customers!

Main advantages of N.E.T. Black Body Source:
• True black body radiation
• Wide wavelength range (2 to 14 μm)
• High emissivity
• Long lifetime
• Fast electrical modulation (no chopper wheel needed)
• Low power consumption
• Rugged MEMS design

Non-Dispersive Infrared sensors for CO2 and Hydrocarbons normally use classic filament lamps as their IR radiation emitter. Such lamps have represented performance and cost-effective IR emittance sources for instruments manufacturers worldwide for years. Filament lamps are commonly limited to an emission spectrum of 500nm and under, as the glass bulb comprising the filament “cuts” all wavelengths beyond 500nm. As CO2, Methane, Propane and other Hydrocarbons all can be observed with absorbance bands below 500nm, a filament lamp works just fine for them.

However, as you can see from the graphic, a large number of gases absorb IR radiation beyond 500nm (or 5µm). To detect them, a filament lamp would be useless.

Common Refrigerant Gases including Sulphur Hexafluoride (SF6) and Ethylene (C2H4) as-well-as all the commonly used refrigerant gases absorb IR Radiation beyond 500nm. To detect them, you would need a source capable of emitting in the spectrum of 8 to 10 µm.

For this specific reason, sensors such as the N.E.T.’S IREF series use a MEMS-based IR source, featuring true blackbody radiation characteristics.

Black body emission is an electromagnetic radiation emitted by an object in a condition of thermodynamic equilibrium. An object is considered a perfect black body when it absorbs all the incoming light and does not reflect any. In theory, a black body source emits energy in the full spectrum of wavelengths, whether in the ultraviolet, visible, infrared spectrums as well as other wavelengths. The black body source emits a known amount of energy for an infinite number of wavelengths. The radiation is emitted according to Planck’s law.

MEMS (Microelectromechanical systems) IR sources have superior speed and efficiency. Surface emitters possess a dedicated emission layer, rendering them highly energy efficient across the entire spectral band. They have a monolithic structure providing excellent resistance against shocks and vibration. It also has smaller energy consumptions than filament lamps, as the source only needs to be powered for a short time.

The use of Black Body Sources allows N.E.T. to extend the classic scope of Infrared sensing, to bring you market’s most comprehensive range of NDIR-detected gases.
