Infrasens 1.11.2016

The INFRA.sens gas measuring module has been specially   developed for usage in high-quality analyzers. In the design phase, we placed particular emphasis on high stability and a low detection limit. With the usage of high-performance light-emitting diodes (IRLED) and thermal micro-emitters, adapted to the needs of gas measurement technology, these goals were achieved. With this novel sensor platform we can reliably detect carbon dioxide, carbon monoxide, hydrocarbons, water vapor and sulfur hexafluoride up to the ppm range in the spectral range from 2 µm to 12 µm.


Modular sensor design

In order to adapt the measuring system to a new measurement task as flexible as possible, we have designed the individual components interchangeably. This gives us a modular kit with different components such as measuring unit, blasting unit, cuvette etc. which are interchangeable. When choosing the cuvette material, we can therefore also take advantage of all available materials such as aluminum, stainless steel glass ceramics and more. Also, it is possible to provide internal coatings in order to improve the reflective properties and increase the corrosion resistance.

With this sophisticated sensor design, „exotic“ applications can be implemented without the need for a complete new development.

Due to the decomposability, the replacement and maintenance is simpler. Since completely glued sensors have to be replaced completely, high follow-up costs (total cost of ownership) would incurre.
