Applications

The Liquiphant FailSafe is a point level switch for minimum and maximum detection (MIN/MAX) which can be used in liquids:

  • Process temperatures 60 to 280 C (76 to 536 F)
  • Ambient temperatures 60 to 70 C (76 to 158 F)
  • For highly corrosive media
  • Pressures up to 100 bar (1450 psi)
  • Viscosity up to 10000 mPas
  • Density from 0.4 g/cm3 (0.4 SGU)

Liquiphant FailSafe is the reliable point level switch for MIN and MAX safety applications up to SIL3.

Outstanding features of the point level switch are its fail- safe design and its high availability.

A permanent LIVE signal also monitors function safety.

Your Benefits
  • 4-20 mA interface (acc. to NAMUR NE 06/NE 43): easy integration via the switching unit (Nivotester FailSafe FTL825) with a two-channel output (safety contacts) and locking function or direct integration into a safety PLC
  • Use in safety systems requiring functional safety to SIL3 in accordance with IEC 61508 Ed.2.0/IEC 61511-1/ISA 84-1 and DIN EN ISO 13849
  • Proof test: proof testing interval up to 12 years
  • Slave devices tested at the press of a button
  • Permanent self-monitoring/internal redundancy
  • No adjustment: quick, low-cost startup
  • No mechanically moving parts: no maintenance, no wear, long operating life
  • Monitoring of fork for damage, corrosion, buildup and mechanical blocking
  • 2. process seal (2 nd line of defense) is provided as standard in the high-temperature version or can be optionally selected for all other versions
Point level detection

Maximum or minimum detection for liquids in tanks or pipes (leak monitoring, dry running protection/pump protection or overfill protection), particularly for the chemical, energy and oil & gas industry.

Special versions are suitable for use in hazardous areas and for applications with high pressures. As a coated version, the Liquiphant FailSafe is highly resistant to corrosion, making it particularly suitable for very aggressive liquids.

The point level switches make a distinction between two states: "covered" and "exposed" Depending on whether you have selected the MIN (minimum detection) or MAX (maximum detection) operating mode, this results in two specific scenarios in each case: the "Good" state and demand mode.

"Good" state:
The fork is covered in the MIN operating mode (e.g. pump protection).
The fork is exposed (uncovered) in the MAX operating mode (e.g. overfill protection).

Demand mode:
The fork is exposed (uncovered) in the MIN operating mode (e.g. pump protection).
The fork is covered in the MAX operating mode (e.g. overfill protection).

Measuring principle

The sensor's fork vibrates at its intrinsic frequency. When the tuning fork is immersed in a liquid, its intrinsic frequency changes due to the change in density of the surrounding medium. This change in frequency causes the current signal to switch.
