NDIR Gas Sensor Modules

smartGAS gas sensors use infra-red absorption of gases (NDIR technology) and thus are accurate, reliable and cost-efficient. They are suitable for an extremely wide variety of applications in process measuring technology and ambient air monitoring. As a solutions provider for gas sensor technology, smartGAS can offer custom solutions.  Gases include:

CO & CO2
Acetone, n-butane, ethane, methane & propane
Refrigerant gases
NOX and other pollutant gases

These NDIR gas sensors work without moving parts or chemical reactants. This minimizes the maintenance work and thus the operating and servicing costs compared with other gas sensor technology. These gas sensors are environmentally friendly, long-lasting and reliable.  You too can benefit from smartGAS' expertise!

 

The functional principle of smartGAS sensors & modules

The IR principle uses the individual absorption spectrum of the gas being measured. The exact gas concentration is determined through precise quantitative analysis of this spectrum. Because of this, their gas sensors function very selectively and are virtually unaffected by other environmental factors or gases.


The functional principle of our gas sensors: long-term stability and performance thanks to NDIR technology from smartGAS

As all measured gases absorb in varying spectral ranges, a kind of "fingerprint" arises that allows very selective characterization without cross-sensitivities. Gas sensors from smartGAS possess an integrated electronic evaluation system that displays a simple to use concentration signal to you as the user and reliably compensates for all drift and temperature influences.

 

Gas sensors for the process measuring technology

The precise and selective gas sensors from smartGAS are distinguished by simple handling and cost efficiency – even in demanding applications. Knowledge of the internal flows and current state of a process is essential for the control and cost-efficient operation of plants. If measurements are lost, or if they cannot be used, this can lead to high costs. We possess this knowledge and incorporate it in your application as a solution. Our optimized optical components, in combination with the adapted software, ensure high long-term stability and performance – for your application too. In contrast to chemically-based gas sensors, their products are not only lower-maintenance and longer lasting, but also detect even chemically inactive gases quickly and reliably.

Gas sensors for ambient air monitoring

The monitoring of gas concentrations in the ambient air requires especially long-term stable and reliable gas sensors. The measurements are usually carried out 24/7 – 365 days in the year. Reliability and insensitivity to external influences therefore make gas sensors from smartGAS the first choice for your measuring task.
