Introduction

OVERVIEW

ABOUT THE TRANSMITTER

This manual is designed to assist in installing, operating, and maintaining the Rosemount 1154 Pressure Transmitter. The manual is organized into the following sections:

Section 2: Installation

Provides general, mechanical, and electrical installation considerations to guide you through a safe and effective transmitter installation.

Section 3: Calibration

Provides transmitter calibration procedures.

Section 4: Operation

Provides descriptions of how the transmitter operates.

Section 5: Maintenance and Troubleshooting

Provides basic hardware troubleshooting considerations including sensing module checkout, disassembly and reassembly procedures, and post-assembly tests.

Section 6: Specifications and Reference Data

Provides nuclear, performance, functional, and physical transmitter specifications; also includes ordering information, and a list of spare parts.

Rosemount 1154 Pressure Transmitters are designed for precision pressure measurements in nuclear applications requiring reliable performance and safety over a specified qualified life. These transmitters were generically tested to the IEEE Std 323-1974 and IEEE Std 344-1975 per the Qualification Test Report D8400102. The Rosemount 1154 has been qualification tested to environments typical of Pressurized Water Reactors (PWR) under accident conditions. Stringent quality control during the manufacturing process includes traceability of pressure retaining parts, special nuclear cleaning, and hydrostatic testing.

Rosemount 1154 Transmitters are uniquely built to Class 1E nuclear service while retaining the working concept and design parameters of the Rosemount 1151 Series that have become a standard of reliable service. Units are available in gage (G), differential (D), and high-line differential (H) configurations, with a variety of pressure range options, as shown in Table 6-1 on page 6-8. Figure 2-5 on page 2-7shows dimensional drawings for the transmitters.
