Abstract
A urea sensor protection assembly for protecting a fluid sensor of a urea sensor system comprises an inner cage supporting the fluid sensor and an outer cage. The inner cage has a first fixation element fixing the inner cage to a common holder. The outer cage has a filter capable of blocking a plurality of air bubbles and/or allowing a fluid to pass and a second fixation element fixing the outer cage to the common holder. The inner cage is at least partially arranged in an inner volume of the outer cage in an assembled state.
