How to determine mounting position (large sensor)
Determine the mounting position by carrying out the following work.
For this work, gauge paper is necessary (For the gauge paper, refer to page 7-10).
q
Match the edge of gauge paper with the line at
about 100mm from one end of the pipe portion
treated for detector mounting, and wind the
gauge paper so that the line marked on the paper
is parallel with the pipe axis (fix with tape not to
allow deviation). At this time, the edge of gauge
paper should be aligned.
w
Extending the line marked on the gauge paper,
mark straight line A on the pipe.
e
Mark a line along on edge of the gauge paper.
The intersection of this line and straight line A is
replaced with A
0
.
r
In mounting by the V method, peel the gauge
paper and measure the mounting dimension from
A
0
to determine A
2
position. At this position,
mark a line orthogonal to the straight line A.
A
0
and A
2
become the mounting positions.
Example) L = 200mm
t
In mounting by the Z method, measure the
circumference from A
0
with a measuring tape.
At 1/2 of the circumference, determine points B
0
and B
1
, and mark a line (straight line B)
connecting those points.
y
Mark the points B
0
and peel off the gauge paper.
Measure the mounting dimension from B
0
to
determine B
2
position. At this position, make a
line orthogonal to the straight line B.
A
0
and B
2
become the mounting positions.
Example) L = 100mm
Align this edge.
