  • No calibration: quick and low-cost start up
  • No mechanically moving parts: maintenance-free, no wear, long operating life
  • Monitoring of the vibrating fork for damage: guaranteed function
  • PROFIBUS PA protocol: commissioning and maintenance quick and easy
  • Up to SIL 2 acc. to IEC/EN 61508

Please note: All product-related documents, such as certificates, declarations of conformity, etc., which were issued prior to the conversion under the name Pepperl+Fuchs GmbH or Pepperl+Fuchs AG, also apply to Pepperl+Fuchs SE.

General specifications
Function principlelimit detection
Maximum or minimum detection in tanks or pipelines containing all types of liquids including use in explosion hazardous areas. Particularly suited to very aggressive liquids thanks to high degree of corrosion protection.
Measuring methodThe forks of the sensors vibrate at their intrinsic frequency. This frequency is reduced when covered with liquid.
The change in frequency then activates the limit switch.
Construction typecompact device
SeriesVibracon LVL-M1

Input
Switching pointsee section switch point
Measured variablelimit level (limit value)
Measurement rangedepends on mounting point
Output
Switching delaywhen fork is covered: approx. 0.5 s, when fork is exposed: approx. 1.0 s (other switching times on request)
additionally configurable for PROFIBUS PA (electronic insert FEL50A (PA)): 0.5 ... 60 s
Switch behaviourswitch-over for minimum/maximum residual current safety on electronic insert
MAX = maximum safety:
The output switches to the power fail response when the fork is covered.
for use with overspill protection for example
MIN = minimum safety:
The output switches to the power fail response when the fork is exposed.
for use with dry running protection for example
When switching on the power supply the output assumes the alarm signal. After max. 2 s it assumes the correct switching mode.
Directive conformity
Electromagnetic compatibility
Directive 89/336/EECEN 61326
If the fork tines are joined together on account of build-up, the useful signal is attenuated to such an extent that the original EMC values can no longer be completely observed (EN 61000-4-3 electromagnetic fields,
EN 61000-4-6 HF coupling).
