Abstract

A non-contacting surface contour measurement device includes movable member which can selectively be actuated to form a hermetic enclosure about a transmit and/or receive antenna. The measurement device, when employed in a blast furnace, need be exposed to the furnace environment only during measuring modes which constitute a small portion of the furnace operating cycle.
