C.2 Mounting RTDs on the Pipe
The factory supplies a clamping fixture to mount the RTDs to the pipe; 
however, you must assemble the clamping fixture before you can mount the 
RTDs to the pipe. Use the following instructions below to mount the RTDs.
C.2.1 Assembling the Clamping Fixture
The clamping fixture consists of the following parts:
one strap (length depends on the pipe size)
a screw buckle
a feeder buckle
To assemble the clamping fixture:
1.
Cut the strap equal to the circumference of the pipe.
2.
Fold 1/2 inch of one end of the strap into a hook shape.
3.
Secure the screw buckle to one end of the strap by placing the strap 
through the buckle and folding the strap.
4.
Crimp the strap closed to secure the screw buckle in place.
5.
Each RTD has a securing post (located on the rounded portion of the 
RTD) that secures the RTD in place when it is mounted on the pipe. 
Place the RTD on the strap by sliding the strap under the securing post.
IMPORTANT:
Make sure you place the RTD on the strap so   when the strap 
is wrapped around the pipe, the flat surface of the RTD sits 
against the pipe.
6.
Secure the feeder buckle to the other end of the strap by placing the 
strap through the buckle and folding the strap (the folded section should 
be approximately 1/2 inch). 
7.
Crimp the strap closed to secure the feeder buckle in place.
Repeat steps 1 through 7 for the remaining RTD and clamping fixture. 
When you have completed assembly, proceed to the next section to fasten 
the RTD to the pipe.
