A reduced thermal conductivity thermal barrier coating having improved impact and erosion resistance for an underlying metal substrate of articles that operate at, or are exposed to, high temperatures. The transmission circuit transmits a first data of a first bit length for a first burst times by a burst transmission. Respective first and second portions of the flow are directed through the filter elements and impinge opposing sides of a piston member which is biased in a first position by a collapsible pressure responsive member, such as a buckling pin.
