1. A laundry washing machine, comprising:
a housing;
a wash tub disposed within the housing and including a wall facing an interior of the wash tub; and
a low profile conductivity sensor coupled to the wash tub to sense conductivity of a fluid disposed in the interior of the wash tub, the low profile conductivity sensor including:
a sensor housing coupled to the wall of the wash tub and having a housing surface facing the interior of the wash tub and extending substantially parallel to the wall of the wash tub; and
first and second electrodes disposed in the sensor housing and extending substantially parallel to the wall of the wash tub and to one another, the first and second electrodes having respective sensing surfaces that are substantially flush with the housing surface of the sensor housing.
