Note: Maximum Allowable Working Pressure (MAWP) may vary with materials of construction and process
temperature. For more specific information, refer to the appropriate Specification and Model Selection
Guide. In transmitters with Graphite Gaskets, rating of 50 psi remains unchanged while ratings of 4500
psi are reduced to 3625 psi (250 bar). Flange Adapters with Graphite Gaskets have a 3000 psi rating.
NOTE: To convert bar values to kilopascals (kPa), multiply by 100.
For example, 3.5 bar equals 350 kPa.
