Abstract

This paper discusses the advantages that can be achieved by replacing traditional filter wheel constructions with integrated multichannel detectors in infrared process analyzers which are used in hostile industrial environments. The two fabricated detector constructions described are a basic two-channel thermoelectrically cooled detector and a self-contained four-channel detector assembly in which all the supporting functions needed by photoconductive lead-salt detectors are incorporated. The paper also deliberates upon the limitations of the multichannel detector technique and presents the performance level attained in the accomplished detectors.
