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).

Density

Liquids with density > 0.7 g/cm
Switch position > 0.7 g/cm
Liquids with density 0.5 g/cm
Switch position > 0.5 g/cm
Liquids with density > 0.4 g/cm
• Optionally available, not suitable for SIL applications
• Fixed value that cannot be edited
The function of the DIP switch is interrupted
For distinguishing between media/density detection, use the Liquiphant Density
(FEL60D) with a density computer.
