1. An infrared spectrometric monitoring transducer, comprising:

  • a shielded cable;

    a fiber optic light guide;

    a transducer housing;

    a light source operable to produce a light signal along a plurality of discrete wavelengths, mounted in the transducer housing;

    at least one light detector operable to receive light energy corresponding to the light signal, mounted in the transducer housing spaced a distance apart from the light source along a straight line extending the light source and the at least one light detector;

    wherein the shielded cable and the fiber optic light guide are disposed adjacent the light source and the transducer has an “

    L”

    shape formed by the shielded cable and the fiber optic light guide extending outwardly from the transducer housing in a direction substantially perpendicular to the line between the extending the light source and the at least one light detector.
