Re: Notification under 10 CFR Part 21 for Rosemount Model 1154 Alphaline
Nuclear Pressure Transmitter, Range Code 0, Drift Specification
Pursuant to 10CFR Part 21 Paragraph 21.21 (b), Rosemount Nuclear
Instruments, Inc. (RNII) is writing to inform you that the drift
specification for Model 1154, gage pressure transmitters, range code 0,
is not correctly described in Manual MAN 4514, December 1992. Manual MAN
4514, December 1992, page 4-1, Drift is incorrectly stated as +/-0.2% of
upper range limit for 30 months. The correct specification is +/-0.3% of
upper range limit for 30 months.
The Product Data Sheet for Model 1154, #00813-0100-4514, November 1995,
page 4, Drift, shows +/-0.2% of upper range limit for thirty months (+/-
0.3% of upper range limit for range 0). This is the correct drift
specification for this model, since +/-0.2% of upper range limit applies
to all range codes other than range code 0.
This notice does not apply to other Model 1154 gage pressure
transmitters, nor to any Model 1154 differential or high line
differential pressure transmitters. Moreover, it does not apply to any
Model 1152, 1153 Series B or D transmitters.
The design and qualification of Model 1154 Range Code 0 is based on
design and qualification of Rosemount Model 1153 Series D Alphaline
Nuclear Pressure Transmitter, In turn, Model 1153 Series D design and
qualification references Model 1153GD0, whose qualification is documented
in Rosemount Report 78215. The range code 0 sensor module is designed to
operate between 0 and 6000 psi. However, the specified upper range limit
on model 1154 range code 0 pressure transmitter is 4000 psig. This means
the specified upper range limit on range code 0 is actually "ranged down"
from its design limits. There are "range-down" effects associated with
operating the transmitter at levels lower than the design limit. More
specifically, the transmitter gain must be turned up in order to
calibrate the transmitter from 0 to 4000 psig, which amplifies any zero
errors. This means that some of the errors in performance, including
drift, must be magnified by the "range-down multiplier" of 1.5. The
correct drift specification for range code 0 is +/-0.3% of upper range
limit as properly indicated in Product Data Sheet for Model 1154, #00813-
0100-4514, November 1995.

complete that action;
Until such time as the manual containing the error is fully revised,
errata sheets will be issued and included in all future shipments of
current revision (December 1992) 1154 Manuals, stating the correct
drift specification to be +/-0.2% of upper range limit for thirty
months (+/-0.3% of upper range limit for range 0). Additional
errata sheets will be made available for users requesting them to
include in 1154 manuals already shipped from RNII.
The above actions will be completed within 6 months of this
notification.
No further action related to this issue is expected. Mr. Schmitt is
