<p><P>PROBLEM TO BE SOLVED: To obviate hindrance to the traffic of vehicles for work and of workers owing to a microwave distance meter disposed on a floor surface located above an object under inspection as in the case of a blast furnace for example, to reduce disassembling and reassembling work in maintenance, and further, to enhance detection accuracy. <P>SOLUTION: In this microwave distance meter, a guide pipe for propagating a microwave through its internal space is disposed above the object under inspection while an antenna is disposed on an end part of one opening of the guide pipe so that its transmission/reception surface confronts the opening. A reflector is disposed on an end part of the other opening for reflecting the microwave toward the object while guiding the reflected microwave to the guide pipe, with the microwave being transmitted from the antenna and propagating through the guide pipe. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
