Subject: Introduction of Rosemount 3150 Series Nuclear Pressure Transmitters and Discontinuance of
1150 Series Nuclear Pressure Transmitters
Dear Valued Customer,
For over 35 years, Rosemount Nuclear Instruments, Inc (RNII) has been a leading supplier of nuclear
qualified pressure instrumentation built upon the technology of the 1150 Series Pressure Transmitter.
While the 1150 Series has been a critical and unparalleled product for the nuclear power industry, it has
become increasingly challenging to support, manufacture, and maintain the qualification- primarily due to
the obsolescence and limited availability of a growing list of electrical components.
With this backdrop, RNII is excited and proud to introduce its 3150 Series Nuclear Pressure Transmitter
Family- the culmination of extensive, continued investments in improved core sensing technology,
electronics design and overall transmitter performance. The 3150 Series has been rigorously designed to
ensure long-term manufacturability and reliability for nuclear customers. As Figure 1 illustrates, the
product tiers and capabilities have also been expanded to incorporate a broader set of customer
requirements which envelope and exceed that of the legacy 1150 series.

As RNII launches the 3150 Series Nuclear Pressure Transmitter and Remote Seal Family, we will also be
initiating a multi-phased process to discontinue the 1150 Series Nuclear Pressure Transmitter and
Remote Seal Family with a full transition to the next generation platform. As noted in the milestone
schedule below (Figure 2) the 3152 is immediately available and will be proposed as a possibility in all
appropriate quotations.
The balance of the 3150 Series is pending final IEEE qualification, which is currently underway. RNII will
provide on-going updates to the below dates and corresponding milestones as appropriate to ensure a
smooth transition to the 3150 Series. For customers requiring KTA qualification, 3152K and 3154K are
qualified and available for consideration today.
Note 1:
= Target date of last orders based on availability of 3150 replacement
Note 2: Timing of discontinuance is subject to parts availability. RNII reserves the right to limit order
quantities and shipments during the transition period as necessary to best serve all users.

APPENDIX A: Transition From 1150 Series to 3150 Series
Frequently Asked Questions (FAQ)
Q: Why is Rosemount Nuclear introducing the 3150 Series and discontinuing the 1150 Series?
A: 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 November 15, 2012 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.
Q: Does the 3150 Series utilize fully analog or microprocessor based electronics?
A: The 3150 Series is 100% analog! 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 V&V, EMC, evolving regulatory requirements, ability to withstand
radiation and other harsh environment conditions, and the ability to provide long term availability.
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 LTB’s 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 posted as available. Please contact RNII for
additional information.
Q: What is the standard leadtime for the 3150 Series?
A: The typical leadtime is expected to range from 4-10 weeks after receipt of order, depending upon the quantity
requested. As always, RNII will work closely with the industry to meet customer expected leadtimes, including expedited
shipments to accommodate emergent outage needs.
Q: Is a more detailed comparison between the 1150-Series and 3150-Series available?
A: For your convenience, RNII is generating a comparison table as a quick reference which will be available at
www.RosemountNuclear.com . The chart will include comparisons on:
* Qualification levels
* Design basis event profiles
* EMC qualification testing performed
* Normal operating performance
* Physical and functional specifications
For complete details, please refer to the applicable product data sheets and qualification report.

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: 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 3,800
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.
