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 or transmitter nameplate

Note: To convert bar values to kilopascals (kPa), multiply by 100. For example, 3.5 bar equals 350 kPa.
