Diaphragm Seal Systems

Quick Start Guide June 2022

NOTICE

This guide provides basic guidelines for the Rosemount DP Level Transmitters and Diaphragm Seal
Systems Reference Manual. It does not provide instructions for configuration, diagnostics,
maintenance, service, or troubleshooting. Refer to the appropriate reference manual for more
instruction. This guide are also available electronically on Emerson.com/Rosemount.

WARNING

The products described in this document are NOT designed for nuclear-qualified applications. Using
non-nuclear qualified products in applications that require nuclear-qualified hardware or products may
cause inaccurate readings.

For information on Rosemount nuclear-qualified products, contact your local Emerson Sales
Representative.

Physical access

Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end
users’ equipment. This could be intentional or unintentional and needs to be protected against.

Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.

1 Introduction

A remote seal system consists of a pressure transmitter, a remote seal, and
either a direct mount or capillary style connection filled with a secondary fill
fluid. During operation, the thin, flexible diaphragm and fill fluid separate
the pressure sensor of the transmitter from the process medium. The
capillary tubing or direct mount flange connects the diaphragm to the
transmitter. When process pressure is applied, the diaphragm is displaced,
transferring the measured pressure through the filled system, by way of the
capillary tubing, to the transmitter. This transferred pressure displaces the
sensing diaphragm in the pressure sensor of the transmitter. This
displacement is proportional to the process pressure and is converted
electronically to an appropriate output current and/or digital protocol.

2 Preface

This guide is designed to assist with general handling and installation
instructions for the Rosemount DP Level Transmitters and both 1199 and
1299 Diaphragm Seal Systems. The Rosemount DP Level Transmitters and
Diaphragm Seal Systems Reference Manual contains supplemental
information about the seal system assemblies that are not covered in the
corresponding transmitter manuals.

3 General handling overview

Check if equipment received conforms to the order. If any issues, contact
your local Emerson sales representative immediately.

When unpacking or handling seal system assemblies, do not lift the seal or
transmitter by gripping the capillaries, doing so could result in disconnecting
the seal and/or capillary from the transmitter, which will void the warranty.

The material of a remote seal is designed to withstand pressure and wear
from process material, but outside of process connection conditions,
remote seals are delicate and should be handled with care.

The protective cover should remain on the seal until the moment before
installation. Try to avoid touching the diaphragm with fingers or objects and
refrain from setting the diaphragm side of the seal down on a hard surface.
Even minor dents or scratches in the diaphragm material may impair the
performance of the seal system assembly.

Avoid sharply bending or crimping the capillary tubing. The minimum
bending radius of the capillary tubing is 3-in. (8 cm).

When using heat or steam tracing, exercise caution if PVC coating is added
onto capillary. The PVC coating on the armor will break down at
temperatures around 212 °F (100 °C). Best practice for heat and steam
tracing is to regulate the temperature above the maximum ambient
temperature for a consistent result. To avoid accuracy effects and thermal
stress, the capillary should not be partially heated.
