Modular sensor design

Analyse up to 4 different gases plus pressure and humidity simultaneously

In order to adapt gas analysis as flexibly as possible to individual measurement tasks, the single components were designed modularly. This resulted in a »modular system« in which the various photometric components such as detectors, emitters, measuring sample cell, etc. can be assembled user-specifically.

With this sophisticated sensor design, customer-specific applications can be realized without needing a completely new development. The modularity makes replacement and maintenance considerably easier when servicing is required. In contrast to this design, common completely glued gas sensors can only be replaced as a complete unit thus generating high follow-up costs (total cost of ownership) in case of maintenance.

Optionally, modules can also be equipped with a sensor for oxygen, pressure and humidity.

Humidity Sensor

The HUMI.sens® is based on a capacitive humidity sensor. This sensor consists of a hygroscopic polymer material in which the water vapor from the measurement gas is stored. This incorporation

IR-Photometry

Within the infrared spectral range between 2 µm to 12 µm or 14 µm the IR photometry can detect different gases. This spectral range is much larger than the UV

UV-Photometry

The UV photometry is based on the absorption of radiation in the spectral range between 200nm and 400nm. In this area, some important technical gases have a pronounced absorption band.
