Flanged / threaded diaphragm seal system that protects pressure / level / DP transmitters from corrosive, erosive, or extreme-temperature process media. Same isolation benefits as the 1199 family but with a streamlined model code, an 800-PSI threaded connection rating option, and a wider material variety. Mounts directly to flanged or threaded process connections — no separate mounting hardware required, reducing installation cost. Supports gauge, absolute, and DP transmitters; usable as a remote seal where physical size fits. SIL 2/3 third-party certified to IEC 61508.
