The Gauge Head
Note You may need to adjust chain links (thread more or fewer links
through each slot) to allow for pipe size tolerance, insulation, etc. Start with
approximately 10 cm (4 inches) of play. ▲
8. Position the detector on the pipe, opposite the source mounting plate.
If necessary, use a lift, hoist, or other means to hold it in position.
9. To secure the detector and the source head mounting plate on the pipe:
a. Position the upper chain, including the tensioning bolt assembled
earlier, over the detector’s top mounting arm.
b. Place a spacer ring and two Belleville washers with concave sides
together onto the pilot end of the special nut.
c. Insert the pilot end of the chain tensioning bolt into the hole in the
top detector mounting arm and tighten the chain tensioning bolt
finger-tight.
d. Repeat the previous three steps for the lower chain.
10. Alternately and uniformly tighten the chain tensioning bolts until the
spacers are just touching the mounting arms.
11. Place the loose ends of the upper chain over the top edge of the source
mounting plate so they will not interfere with the source housing
installation.
12. Position the source housing so its four mounting holes engage the four
studs on the mounting plate. If necessary, use a lift, hoist, or other
means to hold it in position.
13. Use the provided lock washers and nuts to secure the source housing.
Pipe Saddle (Cradle)
Mount
A pipe saddle, or cradle, mount consists of two identical mounting plates
that are bolted together on opposite sides of the process pipe.
Refer to drawing 85726N and follow the steps below to install a gauge
head with a pipe saddle mount.
