10.
3. Carefully place the flange (25 or 27) as shown in the exploded view.
Take care not to disturb the O-rings or damage the diaphragms.
4. On differential units, repeat steps 2 and 3 for the low side (“L”) of the
sensor module. For gage units, repeat step 3 for the low side (“L”) of
the sensor module.
5. Keeping the flanges parallel to each other and to the module faces,
insert the four bolts (26) (and washers on Range Codes 9 and 10)
and finger-tighten the nuts (15).
Each spare parts kit contains the correct number of nuts, bolts, and
washers for the specific transmitter range code it is designated for.
Due to recent consolidation of parts kits, the bolt length and quantity
of washers required may differ from existing transmitter assemblies
and/or parts kits. Verify by part number that the appropriate spare
parts kit is used for the transmitter range code being re-assembled.
Contact Rosemount Nuclear Instruments, Inc. if there are any
questions.
6. Evenly seat the flanges on the sensor housing, using a hand torque
wrench. See Figure 5-2 on page 5-6 to identify the bolts.
7. Alternately tighten bolts A and B to 10 ft-lb (14 N-m) torque.
8. Alternately tighten bolts C and D to 10 ft-lb (14 N-m) torque.
9. Check torque on A and B.
10. Check torque on C and D.
11. Repeat steps 7–10 at 15 ft-lb (20 N-m) torque, at 20 ft-lb (27 N-m)
torque, and at 25 ft-lb (34 N-m) torque until all bolts are torqued to 25
ft-lb (34 N-m).
12. Expose Range Code 3 transmitters to two temperature cycles over
the expected operating temperature range before calibration.
NOTE
It is important to orient the back-up ring with the beveled side toward
the process flange. Handle metal ring with care.
