Operation
Cell Cap Assembly
The cell body and both cell caps were manufactured and pressure tested
together. All three pieces are serialized. Before assembling the test cell, make
sure all three pieces have the same serial number.
For a complete diagram of the test cell, refer to pages 59 and 60.
Bottom Cap Assembly
1. Inspect the transducer port to make sure that it is clean and free of debris.
Dried transducer couplant can accumulate on the sides and bottom of the
port. This couplant must be cleaned from the port as well.
2.
Tighten the jaws of the vice on the flats of the cell cap with the threads
facing up.
3.
Apply a thin layer of high-temperature grease to the surface of the bottom
cell cap that meets with the cement. Wipe off any excess grease.
4. For the High Pressure SGSM, install the seal ring (#120-50-027-1)
with the narrow side pointed towards the threads and place the o-ring
(#123-011) on top of it.
For the Low Pressure SGSM, simply place an o-ring in the o-ring groove
on the bottom cell cap. The bottom cell cap does not require a seal ring.
5.
Apply more high temperature grease to the seal ring and o-ring.
The o-ring should be inspected for signs of degradation before installing a
new o-ring.
