Abstract
A sensor assembly is provided for detecting a concentration of a fluid. The sensor assembly includes a sensing unit and a cover assembly. The sensing unit includes a transmitter configured to transmit a signal into a sensing volume and a receiver configured to receive the signal after the signal passes through a portion of the sensing volume. The cover assembly at least partially encloses the sensing volume and is substantially impermeable to a gas portion of the fluid. The cover assembly includes apertures defined therein which are permeable to the gas portion of the fluid. A first plurality of apertures are defined along a top surface of the cover assembly.
