Technical Information
Liquiphant M FTL50(H), FTL51(H)
Vibration Limit Switch
Level limit switch for all liquids.
Suitable for use in hazardous areas, food and pharmaceuticals
Application
The Liquiphant M is a level limit switch for use in all
liquids
– for process temperatures of –50 °C to 150 °C
– for pressures up to 100 bar
– for viscosity up to 10000 mm
2
/s
– for densities 0.5 g/cm
3
or 0.7 g/cm
3
other settings
available on request
– foam detection on request
The function is not affected by flow, turbulence, bubbles,
foam, vibration, bulk solids content or build-up.
The Liquiphant is thus the ideal substitute for float
switches.
FTL50:
Compact design, ideal for mounting in pipes and for
installation in areas difficult to access
FTL51:
With extension pipe up to 3 m
(6 m on request)
FTL50H, FTL51H:
With polished tuning fork and easy-to-clean process
connections and housings for food and pharmaceutical
applications.
High corrosion-resistant AlloyC4 (2.4610) is available for
the fork and process connections for applications in very
aggressive liquids.
EEx ia, EEx de and EEx d protection enable it to be used
in hazardous areas.
