1. A sensor for detecting material deposits in a fluid flow conduit, the sensor comprising:
a body; and
an array of pairs of temperature sensors electrically coupled to each other and disposed within the body, each pair of temperature sensors spaced a distance apart along a primary flow direction of the fluid flow conduit,
wherein the array of pairs of temperature sensors are arranged in multiple rows and columns, and
wherein the rows of the array of pairs of temperature sensors are stacked in a radial direction of the fluid flow conduit.
