1. A toroidal conductivity sensor assembly comprising:

  • a toroidal conductivity sensor having a drive toroid and a sense toroid, said sensor configured for disposition in-situ within a process flow path;

    an analyzer configured to control operation of said sensor;

    a multiple conductor cable configured to communicably couple said sensor to said analyzer;

    a multiple conductor connector disposed to releasably couple a sensor end of said cable to said sensor;

    said connector including a male portion and a female portion configured for mutual, releasable engagement;

    said connector including an intermediate calibration portion configured for being interposed between said male and female portions in communicable engagement therewith;

    said calibration portion configured to block electric signals between said analyzer and said sense toroid, and to pass electric signals between said analyzer and said drive toroid;

    wherein said calibration portion is configured for being temporarily interposed between said male and female portions to effect zero out calibration of said sensor.
