1. A subsea erosion sensor, comprising:
a plurality of individual sensing elements arranged in a stack; wherein each sensing element is separated from an adjacent sensing element by an electrically non-conducting material;
a reference sensing element, wherein the reference sensing element is separated from the closest element of the plurality of individual sensing elements, by an electrically non-conducting material; and
wherein each sensing element has a thickness of at least 0.25 mm, and wherein the erosion sensor further comprises an electrically conducting outer housing containing the sensing elements.
