1. An infrared spectrometric monitoring transducer, comprising:

  • a light source operable to produce a light signal along a plurality of discrete wavelengths, mounted in a first pod;

    at least one light detector operable to receive light energy corresponding to the light signal, mounted in a second pod that is independent of the first pod;

    an electromagnetic interference shielding structure shielding the at least one light detector and mounted in the second pod such that light received by the at least one light detector must pass through the electromagnetic interference shielding structure; and

    a light-shielding flexible member extending between the first and second pods.
