Complete the following:
(Item numbers referenced in the following steps are detailed in Figure 2.)
1)
Remove the 1.315”
shipping tube
(Item 6) from the back of the transducer and discard. At
this point, the shipping spacer, or shipping pin, can be removed and the push rod can be
gently retracted back into the transducer. Perform preliminary tests on the sensors to verify
proper operation (Section 2.1).
2)
Install a length of flush-coupled
connecting rod
(Item 12) into the threaded rod of the
transducer. Use a thread locker if available. Caution: When threading the connecting rod into
the push rod of the transducer, ensure the pin of the pushrod is fully engauged in the slot of
the transducer tube to prevent rotation of internal components.
3)
Slide the
slip joint
(Item 5) over the connecting rod and transducer until the end aligns with
the paint mark located on the
flange to slip joint tube
(Item 8). Tighten the nylon set screws
(Item 16) to maintain this position.
4)
Spacers
(Item 2) should be installed along the connecting rod at 3' (one meter) intervals to
prevent the rod from flexing in the tube. This is done by locating the spacer in its
approximate location and wrapping tape around the connecting rod on both sides of the
spacer using the provided
electrical tape
(Item 13).
5)
Install the
coupling to slip joint tube
(Item 9) into the slip joint until the painted mark aligns
with the other side of the slip joint and tighten the
nylon set screws
(Item 16). Note:
Depending on the gauge length, this tube may couple directly to the
shaft end flange
(Item 4).
6)
For longer gauge lengths, couplings and standard pipes are provided. Use PVC cement to
affix a
coupling
(Item 15) to the slip joint to coupling tube. On the other side of the coupling,
cement a length of
standard pipe
(Item 11). Continue to add couplings, tubes, spacers, and
connecting rod until there is only the shaft end flange to connect.
7)
Attach the provided
o-ring bullet
(Item 7) to the final length of connecting rod. This will
allow the shaft end flange to be slid over the connecting rod without damaging the internal o-
rings. PVC cement the
shaft end flange to coupling tube
(Item 10) to the final coupling. The
o-ring bullet can now be removed and used with other assemblies.

8)
At this point, the gauge length should be established. If minor adjustments are needed, the
nylon set screws in the slip joint can be loosened and either end adjusted to the proper
distance. Note: The assembly should only be adjusted by half the range of the sensor in either
direction from the painted mark.
