All good things come in …twos. For exactly two included double-operational amplifiers enabling the new miniaturised quad channel detector to operate in current mode. Thus, the LRM-284 is the first of its kind among the PYROMID® multi channel detectors from InfraTec expanding the product range of the Dresden manufacturer.
A Successful Mix
This detector in a TO39 housing operates with a unipolar supply voltage meaning an analyser with low power consumption can be designed-a fact which particularly speaks for the operation of the detector in portable devices.
Significant differences between the LRM-284 and similar detectors operating in voltage mode are demonstrated when comparing the performance. Signal changes will appear faster with the latest innovation from InfraTec and thus the responding behaviour 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 you consider existing detectors on the market as a reference. The Field of View (FOV) is approximately twice as large. Consequently, much more infrared radiation impinges on the sensor elements whereby the signal-to-noise ratio improves accordingly. With regard to the specific detectivity, the advantage over other products offered is even larger. The value surpasses previously typical performance parameters by three-fold.
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. They are shielded from mechanical stress or from other stresses of harsh environments. The compact stack design ensures maximum optical performance and allows the LRM-284 to convince due to its high performance. The thermally compensated detector has been designed primarily for applications of industrial and medical gas sensors.
