High-tech in the Smallest Space
The LRM-292 pyroelectric detector from InfraTec is, next to the LRM-202, the world‘s smallest multi-channel detector with integrated operational amplifier and thermal compensation. With a diameter of only 4.7 mm, the LRM-292 is predestined for measuring low gas concentrations at small measurement volumes. Fast gas changes, low gas concentrations, and short gas exchange times are not a challenge for the pyroelectric detector in a compact TO46 housing.
The LRM-292 and LRM-202 owe their compact design to the tried-and-tested stacked construction method. Its unique design means that both detectors have a field of view (FOV) of 60°, exposing a very large proportion of the radiation to the pyroelectric elements. This generates high amplitudes of the output signal, which supports external signal amplification.
