ENDRESS+HAUSER  FTL51C-AB8KDK1E4AA

The Liquiphant M is a point level switch for use in all liquids.

• for temperatures of –50 °C to 150 °C (-58 to 302 °F)
• for pressure up to 40 bar (580 psi)
• for viscosities up to 10000 mm  /s (cSt)
• for densities of >= 0.5 g/cm3 (SGU) or >= 0.7 g/cm3 (SGU)

The device functions reliably regardless of flow, turbulence, bubbles, foam, vibration, solids content or buildup, making the Liquiphant an ideal substitute for float switches.

All the wetted parts of the sensor (process connection, extension pipe and tuning fork) are coated in enamel or various synthetic materials, making the point level switch suitable for applications in very aggressive liquids.

International approvals certify use in hazardous areas.

• Use in safety systems requiring functional safety to SIL2/SIL3 in accordance with IEC 61508/IEC 61511-1
• Optimally adapted to the process with a wide range of materials for corrosion-resistant coating
• Large number of process connections to choose from
  • Flanges for various standards
  • Universal usage
• No adjustment: quick, low-cost startup
• No mechanically moving parts: no maintenance, no wear, long operating life
• FDA-approved material (PFA Edlon)

Maximum or minimum detection in tanks or pipes containing all kinds of liquids, including use in hazardous areas. Particularly suitable for very aggressive liquids that to high level of corrosion protection.

The sensor's fork vibrates at its intrinsic frequency. This frequency is reduced when covered with liquid. This change in frequency causes the point level switch to switch.
