Overpressure limit

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

Density

Liquids with density > 0.7 g/cm³ (43.7 lb/ft³)
Switch position > 0.7 g/cm³ (43.7 lb/ft³), order configuration
Liquids with density 0.5 g/cm³ (31.2 lb/ft³)
Switch position > 0.5 g/cm³ (31.2 lb/ft³), can be configured via DIP switch
Liquids with density > 0.4 g/cm³ (25.0 lb/ft³)
• Optionally available to order
• SIL for defined media and process parameters on request
• Fixed value that cannot be edited
The function of the DIP switch is interrupted
