Rosemount 1199 Diaphragm Seal System
The Rosemount 1199 Seal System provides a reliable process pressure measurement and prevent the process medium from contacting the transmitter diaphragm.
An 1199 seal should be considered when 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 connection, the application requires the use of flush-mount hygienic connections that facilitates CIP/SIP service, or when there is a requirement for easier cleaning of the process from the connections to avoid contamination between batches.
Features
- Protects transmitter diaphragm from corrosive, erosive or extreme temperature processes
- Wide variety of seals meet varying process requirements and specifications, including industry-specific applications
- SIL 2/3 certified to IEC 61508 (via 3rd party) and prior-use certificate of FMEDA data for safety installations
- Eliminates need for mounting hardware to reduce installation costs
- Adaptable direct mount gage or absolute seal system can be used for pressurized or vented tank applications
- Tuned-Systems can reduce temperature effects by 10-20% and improve response time by 80% vs. traditional installations
- Flanged, threaded, and hygienic process connections
- Meets industry standards such as EN 1092-1, ASME B16.5, JIS B2238, ASME B1.20.1, EN 10226-1, GOST 33259-15, ISO 228-1
- Variety of fill fluids applications including cold temperature, hot temperature, and hygienic and food grade
- Three different capillary diameters allow for optimization of accuracy and time response
- Multiple diaphragm coatings for tough applications including corrosion and hydrogen permeation
- Welded design with no threaded connections
- 100% helium leak tested
- Advanced manufacturing techniques ensure air-free, leak-tight system that is stable over time
- Reliable operation in full vacuum applications
- Backup convolutions on the diaphragm protect seal integrity
- Recessed diaphragms reduce potential for handling damage
