Rosemount 1199 Diaphragm Seal Systems
The Rosemount 1199 seal system provides reliable, remote measurement of process pressure and protects the transmitter diaphragm from hot and cold, corrosive, or viscous processes. Rosemount remote seal systems are designed for reliability in even the toughest applications.
Rosemount 1199 diaphragm seals can be attached to Rosemount 3051S, 3051, 2051, 3095, and 2088 differential, gage, and absolute pressure transmitters. For additional information refer to the technical documentation tab.
