Diaphragm seals isolate pressure instruments from aggressive, viscous, or high-temperature process media. By creating a barrier between the process and sensing element, they help maintain accuracy, reduce contamination risk, and extend the life of gauges and transmitters. They also support easier maintenance and minimize process disruptions.
These seals incorporate a capillary balancing system that compensates for temperature-induced pressure shifts. By allowing both capillaries to expand uniformly, they reduce measurement drift and eliminate the need for heat tracing in many installations. This design offers reliable performance in environments with significant temperature variation.
Flush flanged seals are designed for off-line process connections and are available in standard ANSI flange sizes from 2 to 4 inches, with other sizes available upon request. Pressure ratings typically range from ANSI Class 150 to 2500, with options for additional flange standards depending on process requirements.
Threaded diaphragm seals offer compact, off-line connections in multiple configurations. Options include male or female NPT threads, with types such as flush threaded, offset threaded, and welded mini seals. These seals are rated up to 2500 PSI and are selected based on connection type and installation constraints.
