ABSTRACT
First, a bibliographic overview presents similar experi-
mental devices, and theoretical considerations are
described. Second, materials and methods are described
before presenting our experimental results and a discussion
dealing with operating mode, sensor sensitivity to fouling
(deposit elimination and formation), and potential applica-
tions. The comparison of two operating modes for the
sensor-steady (STR) and periodic (PTR) thermal
regimes-is reported. Finally, the temperature profile and
sensitivity are modeled for the existing sensor geometry.
