What the Vibracon Mini can do

Applications

The Vibracon Mini LVL-A1 is a level limit switch for
all kinds of fluids and is used in tanks, containers
and pipelines.
It is used in cleaning and filtering systems and
coolant and lubricant tanks as an overspill
protection or as a pump protector.
The LVL-A1 is ideal for applications which
previously used float switches and conductive,
capacitive and optical sensors.
It also works in applications which are unsuitable
for these measuring methods due to conductivity,
build-ups, turbulence, flows or air bubbles.
The LVL-A1 is not suitable for hazardous areas,
hygiene areas and areas where the liquid
temperature is over 100 °C.
Benefits
• Operational safety, reliability and universal
applicability through use of the tuning fork
measuring principle
• External test option using test magnet
• On-site control using external LED display
• Easy to install even at points difficult to access
due to compact construction
• Rugged stainless steel housing (316L)
• Service-friendly plug-in connections

Functional description

The tuning fork of the LVL-A1 is excited to its
resonance frequency by means of a piezoelectric
drive.
This frequency changes if the tuning fork is
covered by fluid.
The LVL-A1 electronics monitor the resonance
frequency and indicate whether the tuning fork is
oscillating freely or whether fluid is covering it.
