Rosemount 1199 Diaphragm Seals

The Rosemount 1199 diaphragm seal systems offer protection to transmitters, guarding against hot and cold, corrosive or erosive processes. They consist of one or two seals, a fill fluid, and either a direct mount or capillary style connection.

Seal systems provide a reliable process pressure measurement and prevent the process medium from contacting the transmitter diaphragm. Please consider using one in the following situations:

• The process temperature is outside of the operating ranges of the transmitter
• The process is corrosive and/or requires specific exotic materials of construction
• The process contains suspended solids or is viscous and is prone to plugging of connections
• The application requires the use of flush-mount hygienic connections that facilitates CIP/SIP service
• There is a requirement for easier cleaning of the process from the connections to avoid contamination between batches
