  • Infrared radiation detector units and methods of assembling transducers in which said units are incorporated
    Patent number: 5793044
    Abstract: A transducer for nondispersive infrared radiation (NDIR) gas analysis and a passive device for verifying the calibration of the transducer. The calibration verification device can be mounted on a cable by which the transducer is attached to an associated signal processing-control-display unit (SPCDU) or monitor. Calibration parameters for the transducer are stored in a plug at the monitor end of the cable. The transducer includes an integrated subassembly of an infrared radiation source unit, an infrared radiation detector unit, and a flex connector and may be employed with an airway adapter preferably maintained by a thick film heating element at an above-dewpoint temperature to ascertain the concentration of a specie potentially present in gases flowing through the adapter. The transducer may also be employed for other purposes.
