IOCFR21 Notification 9 September 2002 Page 2 of 3 3.0 Identification of firm supplying the item:
Rosemount Nuclear Instruments, Inc.
12001 Technology Drive Eden Prairie, MN 55344 4.0 Nature of the failure and potential safety hazard:
During the course of quality testing and data review, RNII has determined that certain Model 1153 differential pressure transmitters and spare sensor modules may not meet the published temperature effect specification. The temperature effect specification establishes an expected analog output error interval during normal ambient temperature variations occurring between 40°F (4.40C) and 200OF (93.30C). While analysis is still ongoing, the root cause of the potential nonconformance has been narrowed to the effect of temperature changes on the transmitter module Based on data review and analysis, RNII has established the following ambient temperature effect specification for transmitters affected by this notification. This specification supercedes the published temperature effect specification for all pressure transmitters affected by this notification.
All Range Codes-
+/- 3.0% of Upper Range Limit per 1001F (55 60C)
RNII does not have sufficient information relative to each end user's specific applications to determine the potential safety-related impact to each end user's plant. Each end user must determine the impact on its plant operations and plant safety and take action as deemed necessary.
5.0 The corrective action which is taken, the name of the individual or organization responsible for that action, and the length of time taken to complete that action:
(a)
RNII has expanded its temperature effect test screen to include all model 1153 pressure transmitters to assure that all further shipments of model 1153 pressure transmitters meet RNII's published temperature effect specification.
(b)
RNII has placed a hold on spare sensor module shipments (c)
RNII has established a new temperature effect specification for pressure transmitters impacted by this notification as noted in Section 4.0.
(d)
RNII will verify ambient temperature effect performance to the original specification on any returned Model 1153 differential pressure transmitter or sensor module affected by this notification and repair or replace if required.
(e)
RNII will continue root cause analysis of the temperature effect potential non-conformance.
Action will be taken consistent with the findings of this analysis to assure conformance to RNII's published temperature effect specifications.
Anticipated completion date:
1 November 2002.
(f)
RNII will remove the hold on spare sensor modules when actions per 5.0 (e) are complete.

10CFR21 Notification 9 September 2002 Page 3 of 3 6.0 Any advice related to the potential failure of the item:
The end user must determine the impact of this potential non-conformance upon its plant's operation and safety and take action as deemed necessary. If the end user determines that return of a pressure transmitter or sensor module is required, RNII should be contacted to facilitate the return process.
