The diaphragm seal system is a key component installed at the measurement end of pressure or differential pressure transmitters. Its main function is to establish a reliable physical isolation barrier between the transmitter's sensitive element and the measured process media. It protects the expensive transmitter core from direct contact, erosion, or blockage by harsh or sensitive process media such as high temperature, high viscosity, strong corrosiveness, easy crystallization, toxic, or high-purity substances. The isolation diaphragm withstands process pressure and transmits it losslessly to the transmitter sensor through an incompressible fill fluid, while ensuring measurement accuracy and response speed. It significantly extends the transmitter's applicable range and service life, and is a guarantee for measurement

Accessory component

The Rosemount 1199 diaphragm seal system protects the transmitter diaphragm from cold, hot, corrosive, or viscous process media. The seal system offers a variety of solutions, including special seals for difficult process industries. The safety-certified system requires no installation hardware and can be used for various pressure measurement applications, providing reliable remote measurement.
