Stack Design Meets Current Mode

The LRM-284 is the latest pyroelectric detector from InfraTec in TO39 housing. It extends the family of miniaturized multichannel detectors. Equipped with two double-operational amplifiers it combines the advantages of the innovative stack design with current mode. Since it is a single supply detector, an analyzer with low power consumption can be designed – a fact which particularly speaks for the operation of the detector in portable devices. In comparison with the performance of detectors in voltage mode signal changes will appear faster with the LRM-284 and thus the responding behavior is more dynamic. At the same time, the signal voltage generated in the process is considerably higher. Consequently, the circuit design can be simplified and the detector becomes more resilient against disturbances, which makes the solution of the measuring task significantly easier. The higher signal levels also support the easy integration of the detector into measuring modules.
One step ahead of competitors, other performance parameters also stand out, particularly when one considers existing detectors on the market as a reference. The Field of View is approximately twice as large. Consequently, much more infrared radiation impinges on the sensor elements whereby the signal-to-noise ratio improves accordingly. Resilient and powerful Apart from the advantages, whose origin lies in current mode, the LRM-284 combines all qualities that distinguish a PYROMID® multi- channel detector. The aperture of the TO39 housing is (5 × 5) mm2. A robust central window in the cap made of silicon for example, can even be soldered for complete hermetic sealing. Inside the detector are the (2 × 2) mm2 large channel filters, which have an additional cost-saving effect when compared with other detectors of their performance class due to their smaller surface area. Providing thermal compensation it has been designed for applications of industrial and medical gas sensors.
