Function and system design
Vibracon LVL-B1, LVL-B2
Function and system design
Measuring principle A piezoelectric drive excites the vibrating rod of Vibracon LVL-B1, LVL-B2 to its resonance
frequency. If medium covers the vibrating rod, the rod's vibrating amplitude changes (the vibration
is damped). Vibracon’s electronics compare the actual amplitude with a target value and indicates
whether the vibrating rod is vibrating freely or whether it is covered by medium.
A = amplitude
Measuring system Vibracon LVL-B* is a compact electronic switch.
Thus, the entire measuring system only consists of:
• Vibracon LVL-B1 or LVL-B2 with FEM 22 (E5) or FEM 24 (WA) electronic insert
• a supply point and
• the connected control systems, switching units, signalling systems (e. g. lamps, horns, PCS,
PLC, etc.)

Cable specifications Vibracon LVL-B1, LVL-B2
Cable specifications
Use a shielded cable in the event of strong electromagnetic radiation.
Immunity to temperature change of connecting cable
The connecting cables must withstand the ambient temperature +15 K.
Cable entries M20 x 1,5 (cable gland); ½ NPT; G½
Input
Measured variable Level (according to the mounting location and the overall length)
Measuring range
(application) The measuring range depends on the mounting location of Vibracon LVL-B* and the length of the pipe extension selected. The pipe extension is available in the following lengths:
500 mm, 1000 mm, 1500 mm, 20 in, 40 in, 60 in.
Input signal Probes covered !small amplitude
Probe not covered !large amplitude
Measuring frequency 700 Hz ... 800 Hz
Output
Galvanic isolation FEM 22 (E5): between sensor and power supply
FEM 24 (WA): between sensor, power supply and load
Switch behaviour binary
Power-on behaviour When switching on the power supply the output is set to "signal on alarm".
After a maximum of 3 s it switches to the correct output signal.
Fail-safe mode Minimum/maximum quiescent current safety can be switched at electronic insert.
Max. = maximum safety:
When the vibrating rod is covered, the output switches in the direction of the signal on alarm.
Used for overfill protection for example.
Min. = minimum safety:
When the vibrating rod becomes exposed, the output switches in the direction of the signal on
alarm.
Used for empty running protection for example.
Switching delay 0.5 s when the sensor is covered, 1 s when the sensor is exposed
Ex specifications FEM 22 (E5), FEM 24 (WA):
Explosion protection for explosive dust-air mixtures: Dust-Ex, DIP
