Vibration Limit Switch LVL-M3

LVL-M3
  • Vibration limit switch for liquids
  • Large selection of process connections: universal use
  • Wide variety of electronic modules (e. g., relay, thyristor signal output): the right connection for every process control system
  • No calibration: quick and low-cost start up
  • No mechanically moving parts: maintenance-free, no wear, long operating life
  • Operation via push buttons and DIP switches on the electronic insert

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.

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
