1 Permitted pressure rating when the "100 bar (1 450 psi)" option is selected. For exceptions, see the "Process
connections" section. Canadian CRN approval: The maximum permitted process pressure is limited to
90 bar (1 305 psi) only in combination with the CRN approval. More details on the maximum pressure values
are available in the download area of the product page under "www.endress.com".
Optionally available:
• PN: 64 bar (928 psi) at max. 150 °C (302 °F)
• PN: 100 bar (1 450 psi) at max. 150 °C (302 °F)

Overpressure limit

• PN = 64 bar (928 psi): overpressure limit = 1.5·PN maximum100 bar (1 450 psi)
depending on process connection selected
• Membrane burst pressure at 200 bar (2 900 psi)
• PN = 100 bar (1 450 psi): overpressure limit = 1.5·PN maximum150 bar (2 175 psi)
depending on process connection selected
• Membrane burst pressure at 400 bar (5 800 psi)
The device function is limited during the pressure test.
The mechanical integrity is guaranteed at pressures up to 1.5 times the process nominal
pressure (PN).
