Subject: STATUS UPDATE: Discontinuance of 1150 Series Nuclear Pressure Transmitters and availability
of Rosemount 3150N Series Nuclear Pressure Transmitters
Dear Valued Customer,
On November 15, 2012, Rosemount Nuclear Instruments, Inc (RNII) announced the launch of the
Rosemount 3150N Series pressure transmitter family along with a multi-phased process to discontinue
the Rosemount 1150 Series of nuclear pressure transmitters and remote seals. The transition is now fully
underway with many customers already making purchases, installing Rosemount 3150N Series
transmitters in their plants, or beginning their Equipment Qualification (EQ) reviews.
To assure a smooth transition, the Rosemount 1150 Series discontinuance has been coordinated on a
per model basis aligning with the availability of the Rosemount 3150N Series. As communicated, the
final order acceptance date for the Rosemount 1152 transmitter is April 30, 2014. The final order
acceptance date for the Rosemount 1153 & 1154 Transmitters is April 30, 2015 and all Rosemount
1150 Series transmitter shipments are to be completed by September 2016.

As last order dates approach, it is important to reiterate that RNII is discontinuing the Rosemount 1150
Series primarily due to a growing number of obsolete electrical and mechanical components. The
Rosemount 3150N Series portfolio is fully qualified, offers many enhancements over the Rosemount 1150
Series, and is available for purchase immediately. For all of these reasons, RNII strongly discourages
last-time-buying behavior and reserves the right to restrict Rosemount 1150 Series order quantities as
needed to best serve all of our customers. Specifically, Rosemount 1152 supplies are and will continue to
be extremely limited though the last order date of April 30, 2014. The final supplies of Rosemount 1152
Transmitters that do exist will be allocated carefully, potentially with extended lead times. Please view the
updated FAQ section included in this letter to learn more about the Rosemount 1150 Series
discontinuance and overall product transition.
Rosemount’s 40+ year commitment to the nuclear industry remains strong and we will continue to provide
the quality products and support you have come to expect-- throughout the transition and beyond. Thank
you for allowing Rosemount Nuclear and Emerson Process Management to continue to serve you now
and in the future.
Sincerely,

APPENDIX A: Transition from 1150 Series to 3150 Series
Frequently Asked Questions (FAQ)
IMPORTANT
Q: Does the 3150N Series utilize analog or microprocessor based electronics?
A: The 3150 Series is 100% analog and does not use microprocessors! RNII carefully evaluated the potential
use of microprocessor based units in conjunction with industry input and concluded that upgraded fully analog
electronics remained the best solution. Key factors in this decision included cyber security, software Validation &
Verification (V&V), EMC, evolving regulatory requirements, ability to withstand radiation and other harsh environment
conditions, and the ability to provide long term availability.
NEW
Q: How does Rosemount Nuclear intend to support spare parts following the last order dates of the 1150
Series?
A: The full Rosemount 1150 Series spare parts offering will continue to be supported until the published last order
dates, subject to availability. After the 1150 Series last order date, a reduced offering of consumable spare parts,
necessary for typical transmitter maintenance, will continue to be supported for 18 months following final transmitter
shipments. The consumable parts are listed in the table below. After this period of time, 1150 Series spare parts will
no longer be available.

NEW
Q: How do the 3150 Series process connections, electrical connections and mounting dimensions compare to
the 1150 Series?
A: The 3150 Series is designed to essentially be a “like-for-like” replacement for the 1150 Series transmitter. The 3150
Series is the same as the 1150 Series with respect to the following:
* Process connection dimensions
* Electrical connections
* Mounting bracket holes
A more detailed comparison tool is available at www.RosemountNuclear.com.
Q: Why is Rosemount Nuclear introducing the 3150 Series and discontinuing the 1150 Series?
A: The 3150 Series is being introduced to provide an updated and improved nuclear qualified pressure transmitter
family which is sustainable for the life of your plant.
The nuclear qualified Models 1152, 1153 Series B and D, 1154 and 1154 Series H evolved from the now obsolete
Rosemount Model 1151. After 35 years of excellent performance they have become increasingly difficult to maintain
and manufacture- particularly due to obsolescence and limited availability of a growing list of components. RNII
anticipated this and in recognition of evolving world-wide industry requirements, made extensive investments over the
past several years in developing the advanced 3150 Series nuclear qualified pressure transmitter family.
Q: Which 1150 Series products are impacted by this announcement?
A: All Model 1152, 1153 Series B, 1153 Series D, 1154 and 1154 Series H nuclear pressure transmitters along with
the 1159 remote diaphragm capillary system will ultimately be replaced by the Rosemount 3152, 3153, 3154, & 3155
along with the 3159 improved remote diaphragm capillary system. The only exception will be the 1152 with “L” output
(10-50mA) which will continue to be available at this time.
Q: When does the 1150 to 3150 Series transition begin to take effect?
A: The transition dates are as noted in RNII’s October 21, 2013 letter. These dates are based upon current and
expected 3150 Series availability, historical 1150 Series order rates and available 1150 Series components. Target
last time ordering and shipping dates are provided to assist customer’s long term planning. Updates will be provided
as applicable. The product transition timeline can also be found at www.RosemountNuclear.com/Transition.
Q: Will 1150 Series Last Time Buy (LTB) opportunities be provided?
A: The 3150 Series is intended to provide continuous qualified pressure transmitter availability to preclude the
necessity for LTB’s. In light of this, reasonable, limited quantity purchases will be accepted with the clarification that
RNII reserves the right to restrict 1150 Series order quantities to accommodate the needs of all users. All sales are
also subject to 1150 Series parts availability.
Q: Where do I find product literature, manual(s), dimensions and other related information?
A: www.RosemountNuclear.com will have standard information including Product Data Sheets and reference
manuals posted as available. Please contact RNII for additional information.
Q: What information does RNII have on the 3150 Series to support confidence in performance, reliability,
quality- including Operating Experience (OE)?
A: The 3150 Series:
1.
2.
3.
4.
Has been developed, manufactured and tested in accordance with RNII’s internationally approved Quality
System which is structured to satisfy10CFR50 Appendix B, NQA-1, KTA1401, IAEA 50-C-Q, and CSA
CAN3-Z299.1-85, among others.
Incorporates Rosemount’s coplanar variable capacitance sensor technology which has been proven in over
4 million commercial 3051C transmitters shipped since 1988.
Leverages RNII’s proven harsh environment analog electronics.
Has been subjected to extensive, robust testing conducted by RNII throughout our Design Verification
Testing (DVT), Manufacturing Verification Testing (MVT) processes and the various qualification type
testing to KTA 3505, RCC-E and IEEE standards.

Q: Do you have references?
A: To respect customer confidentiality, RNII does not typically publish specific customers, sites, or projects that
have purchased and installed 3150 Series Transmitters. To date, RNII has shipped or taken orders for over 5,000
3150 Series units, including those used in harsh environment, safety related applications in France, Germany,
Sweden, Slovakia, the United Kingdom, the United States, Canada, Argentina, China and the United Arab Emirates.
Q: Are there any different or “special” maintenance requirements for the 3150 Series compared to the 1150
Series?
A: No. Maintenance activities are significantly simplified with the 3150 Series. For example:
1.
2.
3.
Reduced calibration time: Zero and span are non-interacting for most calibrations.
Fewer transmitter and/or board replacements due to EQ Qualified Life (QL): The complete 3150
Series transmitter has a 20 yr QL at 120°F versus the 1153/1154 which have a 10yr QL that is extendable
to 15 yrs with replacement of the amplifier and calibration boards.
3150 Series has simplified electronics with:
a. Single board electronics vs. two boards for 1150 Series
b. Easily adjustable coarse zero selectable jumper for elevated or suppressed zero calibrations (vs. 1150
Series with turret post design requiring jumper wire and soldering)
Q: Will 1150 Series NXXXX and TXXXX “special options” be addressed within the 3150 Series?
A: The majority of functionality provided by the 1150 Series N & T special options has already been incorporated
into the 3150 Series model structure. As always, RNII will work with customers to address specific needs and
establish new special option codes for the 3150 Series when appropriate. Please contact RNII for further information.
