ABSTRACT
In order to detect· dimensional changes due to irradiation, a rather simple device has been developed to accurately measure irradiated specimens of various sizes and shapes. It consists merely of a motor-activated dial indicator assembly "lith a standardized control box for remote operation Hithin the hot cell. The detailed design of this portable and versatile equipment is presented along with available operating experience. Potential applications are discussed.
A remotely operated device to measure a variety of shapes and
thicknesses was designed and tested for hot-cell use by the Postirradi
ation Examination (PIE) Group, Metals and Ceramics Division. The
purpose of this report is to present the design and construction of
the device in sufficient detail so that other experimenters may easily
duplicate the unit without additional design effort. The report covers
both the in-cell measuring mechanism and the out-of-cell motor control
box. Since a certain amount of unique jigging or fixturing is required
for each specific measuring operation, these items are not included in
this report. The measuring head described can be used with a large
number of such fixtures.
Figure I is a cuta'fay sketch of the remote measuring head. A dial
indicator and Bodine motor are mounted on an aluminum block drilled with
hlO 3/4-in. -diam mounting holes and corresponding threaded holes for
locking handles. Two such holes are provided to permit either horizontal
or vertical mounting of the measuring head on a supporting rod. The
unit is enclosed in a 6 X 6 X 6 in.-metal "Budd" box to provide pro
tection to the measuring head during in-cell handling. The box also
