dc.description.abstractThe detailed procedure for constructing subminiature hot-wire sensors is given. The wire used is 0.625 micrometers diameter, 90 per cent platinum/10 per cent rhodium, plated with 30-40 micrometers diameter of silver. For construction, the plated wire is first bent into the appropriate shape, and then soldered onto stainless steel prongs. Portions of the silver are then etched, removing it entirely from a 200 mm-400 mm length of platinum/rhodium wire. Small portions of copper plating are then added to give the disired platinum/rhodium wire sensing length, and to insure that good mechanical and electrical connections exist to the sensor. With this procedure, subminiature hot wire sensors have been constructed which operatewith minimal drift, and are mechanically robust for long periods of time. The sensors have been demonstrated to be a useful research tool for turbulence research because they provide a more accurate means to measure energy levels of small-scale turbulent motions than is possible with other measurement devicesen_US
