Product description:

Liquiphant S
Vibronic high-temperature point level switch for all kinds of liquids

Application
The Liquiphant S is a point level switch which can be used in all liquids
– for process temperatures between –60 °C and 280 °C (300 C for max. 50 h cumulative; without thermal shock restriction)
– for pressures up to 100 bar
– for viscosity up to 10,000 mm2/s
– for density of ? 0.5 g/cm3 or ? 0.7 g/cm3, other settings on request
– foam detection on request
The function is not affected by flow, turbulence, bubbles, foam, vibration, bulk solids content or buildup. The Liquiphant is thus the ideal substitute for float switches.
FTL70:
Compact design, also for pipes
FTL71:
With extension pipe up to 3 m (6 m on request) High corrosion-resistant AlloyC4 (2.4610), AlloyC22 (2.4602) 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.

Your benefits
• Use in safety systems requiring functional safety to SIL2 in accordance with IEC 61508/IEC 61511-1
• With high-temperature resistant components: for process temperatures to 280 °C (300 °C for max. 50h cumulative)
• With welded gas-tight feed-through: maximum safety in the event of damaged sensor
• Process connections from ¾\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\" and small tuning fork dimensions: also for areas difficult to access
• Large number of process connections to choose from: universal usage
• Wide variety of electronics, e.g. NAMUR, relay, DC–PMP, thyristor, PFM signal output: the right connection for every process control system
• PROFIBUS PA interface: for optimum startup and maintenance
• No adjustment: quick, low-cost startup
• No mechanically moving parts: no maintenance, no wear, long operating life
• Monitoring of fork for damage: guaranteed function
