Abstract

See full text

An integrated approach for cleaning an active surface of a petrochemical sensor. Sensors in the petrochemical industry are often deployed in locations where they are prone to fouling. By heating the active surface fouling substances may be removed from the active surface. Heating the surface above a supercritical point of a fluid being sensed may create a fluid that may serve to clean the active surface. Limiting the duration of the applied heating and/or pulsing the heating may mitigate adverse effects of use of high temperatures. A doped active surface, such as a doped diamond window may be designed to have conductive areas in the window that may be used for resistive heating of the window.
