Powerful multi-channel detector for gas analysis offers widest, symmetrical FOV on market

The performance of a gas detector is often defined by two characteristics: the size of its field of view and the size of the pyroelectric elements. The LRM-244 from InfraTec offers an excellent level of performance on both counts.

The miniaturised LRM‑244 belongs to InfraTec’s series of PYROMID® detectorsand combines four channels in one TO8 housing (Ø 15.2 millimetres). An enormous field of view (FOV) distinguishes the detector from the rest of the LRM series. Its extremely large, symmetrical field of view of more than 90 degrees allows infrared radiation to impinge within the greatest possible angular range. In addition to this, pyroelements, each with a particularly large sensitive surface of 2 × 2 mm2, ensure an ideal signal-to-noise ratio.

Characteristic for a model of the LRM series, the LRM-244 has an aperture window of about 8.5 × 8.5 mm2integrated in the cap of the housing. The channel filters, each with an area of 2.8 × 2.8 mm2, are protected inside the detector.

The combination of a large FOV and large-scale pyroelectric elements makes the latest development from InfraTec one of the most powerful detectors in the field of gas analysis. Due to the miniaturised stack design the visual elements are close together. This proves to be particularly beneficial. Thanks to this configuration, the FOV is not only symmetrical but larger than with any other four channel detector. The compact design also opens up the opportunity for users to integrate high-cost components, such as additional sapphire discs, directly into the detector cap. Compared to an external solution, this method saves costs since the integrated sapphire discs require much less space.

First and foremost, the LRM-244 impresses thanks to its features. It opens up new possibilities for all those who are already using a four channel detector for gas analysis and are looking for a more efficient solution. At the same time, users who currently rely on single channel detectors but want to change to a four channel detector, are becoming more flexible. The thermal compensation and optional hermetic sealing additionally facilitates the integration into existing systems.
