Maintenance & Troubleshooting

WARNING
Process leaks could result in death or serious injury.
•
Install and tighten all four flange bolts before applying
pressure.
•
Do not attempt to loosen or remove flange bolts while
the transmitter is in service.
WARNING
Residual process fluid may remain after disassembly of
process flanges. If this fluid is potentially contaminated, take
appropriate safety measures.
WARNING
Replacement equipment or spare parts not approved by
Rosemount Nuclear for use could reduce the pressure
retaining capabilities of the transmitter and may render the
instrument dangerous or adversely impact its qualified status.
•
Use only components supplied with the 3152, 3153 or
3154 transmitter or designated by Rosemount Nuclear
as spare parts for the 3152, 3153 or 3154.
NOTE
Maintenance of traceability of any replacement parts is the
responsibility of the user (see Important
Notice
at the
beginning of this manual preceding Section 1).
GENERAL
CONSIDERATIONS
The Rosemount 3150 Series transmitters have no moving
parts and require a minimum of scheduled maintenance.
Calibration procedures for range adjustments are outlined in
. A calibration check should be
conducted after inadvertent exposure to overpressure, unless
your plant considers this factor separately in the plant error
analysis.
NOTE
Transmitters are factory calibrated at ambient temperature
and pressure to the customer’s specified range. If calibration
is not specified, transmitters are calibrated 0 to Upper Range
Limit (URL).
Test terminals are available for in-process checks. For further
checks, the transmitter can be divided into two active physical
components: the sensor module and the electronics assembly.
An exploded view drawing of the transmitter is provided in
. In the following procedures, numbers in
parentheses refer to item numbers in the exploded view.
