WARNINGF ollow instructionsFailure to follow these installation guidelines could result in death or serious only qualified personnel perform the could result in death or serious not remove the transmitter cover in explosive atmospheres when the circuit is connecting a handheld communicator in an explosive atmosphere, ensure that the instruments in the loop are installed inaccordance with intrinsically safe or non-incendive field wiring transmitter covers must be fully engaged to meet explosion-proof the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations hazardElectrical shock could cause death or serious the sensor is installed in a high-voltage environment and a fault or installation error occurs.

2 High voltage may be present ontransmitter leads and extreme caution when making contact with the leads and leaksProcess leaks could result in death or serious and tighten all four flange bolts before applying not attempt to loosen or remove flange bolts while the transmitter is in equipment or spare parts not approved by Emerson for use as spare parts could reduce the pressure retainingcapabilities of the transmitter and may render the instrument only bolts supplied or sold by Emerson as spare installationImproper assembly of manifolds to traditional flange can damage sensor safe assembly of manifold to traditional flange, bolts must break back plane of flange web ( , bolt hole) but must not contactsensor module WARNINGS ensor module and electronics housingSensor module and electronics housing must have equivalent approval labeling in order to maintain hazardous location upgrading, verify sensor module and electronics housing certifications are equivalent.

3 Differences in temperature classratings may exist, in which case the complete assembly takes the lowest of the individual component temperature classes (forexample, a T4/T5 rated electronics housing assembled to a T4 rated sensor module is a T4 rated transmitter.)Physical accessUnauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users equipment. This couldbe intentional or unintentional and needs to be protected security is an important part of any security program and fundamental to protecting your system. Restrict physical accessby unauthorized personnel to protect end users assets. This is true for all systems used within the facility. CAUTIONThe products described in this document are NOT designed for nuclear-qualified non-nuclear qualified products in applications that require nuclear-qualified hardware or products may cause who handle products exposed to a hazardous substance can avoid injury if they are informed of and understand thehazard.

6 The manual contains information about the seal systemassemblies that are not covered in the corresponding transmitter manuals. Forinformation regarding transmitter configuration, operation, and maintenance, referencethe appropriate transmitter information is organized into the following categories: Remote Seal Systems provides an overview of Remote Seal Systems. Installation contains mechanical and electrical installation instructions. Configuration outlines how to range a DP Level Remote Seal System. Fill Fluids describes the offering of fill fluids available with Remote Seal Systems. Maintenance and Troubleshooting provides techniques for cleaning and maintainingthe system as well as addressing the most common operating problems. Reference data provides resources for product certifications, ordering information,specifications, drawings, and spare Rosemount DP Level Transmitters and 1199 Seal Systems Product Data Sheet or 1299 Seal System Product Data Sheet for more detailed information on specific RosemountRemote remote seal system consists of a pressure transmitter, a remote diaphragm, and either adirect mount or capillary style connection filled with a secondary fill uses both the 1199 and 1299 models for specifying remote seals.

Flushing ring (optional) system temperature effects (process temperatureeffects)Fill fluids expand or contract with temperature changes, creating a volume change that isabsorbed by the diaphragm seal and is seen as back pressure at the transmitter. This backpressure creates a shift in the transmitter reading. For symmetrical or balanced systems,this error is usually minimal due to the back pressure being equal on both sides. However,head temperature effect is still factors that affect seal temperature effect include diaphragm thickness, seal typeand size, capillary length, and inner 2-3 shows how diaphragm size can affect the measurement reading at thetransmitter.

9 For smaller seal sizes, such as the 1 -in. size, the amount of back pressure onthe transmitter causes an additional inH2O (307 mmH2O)error. Moving to the gives inH2O (43 mmH2O)and the largest 3-in. size shown only has inH2O (13mmH2O)error. Using a larger diaphragm can drastically improve performance andprovides a more stable Seal SystemsReference ManualApril done in Instrument Toolkit with Silicone 200 fill fluid with Rosemount 2-3: Back Pressure on Diaphragm Causing ErrorNoteDiaphragm temperature effects decrease as seal size temperature effects (head temperature effects)Density temperature effect is due to the change in specific gravity of the fill fluid caused bya change in ambient temperature. When installed, the weight of the fill fluid will producean initial pressure read by the transmitter, equaling the height between the high and lowconnection taps multiplied by the fill fluid's specific gravity.

10 As ambient temperaturechanges, the fill fluid specific gravity will change causing the weight of the fill fluid tochange, thus changing the pressure read by the transmitter. Density effect will be seen inbothTuned-System Assemblies and Balanced System Assemblies and will have the sameimpact on the transmitter regardless of where the transmitter is time response and performanceThe time response of a system is based on the type of transmitter, its sensor range, thelength and inner diameter (ID) of the capillary, and the viscosity of the fill fluid (which isdirectly affected by the process and ambient temperatures). These factors all play a role inthe overall performance of any seal system. The relationship between system timeresponse and temperature error is illustrated in Figure 2-4.
