Patent ID: 7297408

Claim:
A coating made from a solution comprising an alkoxysilane which is a coating on a transducer of a sensor used to measure a fluid property; wherein the coating has anti-fouling properties that do not substantially interfere with the transducer's ability to measure fluid properties, allowing contact of the fluid and contaminants in the fluid with the sensor itself while preventing said contact from fouling the sensor; wherein the coating is prepared from a solution containing alkoxysilanes, wherein the alkoxysilanes are selected from the group consisting of: a. (3,3,3-trifluoropropyl)trimethoxysilane as represented by the formula: wherein F 3 CH 2 CH 2 C— is a non-hydrolysable side-chain or b. a combination of (3,3,3-trifluoropropyl)trimethoxysilane and methyltriethoxysilane, where the methyltriethoxysilane is represented by the formula: wherein H 3 C— is a non-hydrolysable side-chain.
