• Introduction
The vibrating level sensor, VBL-12, VBL-22, and VBL-32 are made specifically
for solid level measurement in containers. It is designed for minimum density of
bulk solid (loose) 12 lbs. per cubic feet (0.2 g/cm3). Not only fine powders,
ordinary powder, granular materials and pellets, but also for detecting sediments
in the liquids such as sludge, sand, etc. The model VBL is usable in a wide range
of specifications. Since the detecting point is at the tip of the vibration pipe, it is
immune to buildup of the medium on the inside wall of the vessel.

Detecting part which touches
directly to the powders. It
vibrates when there’s no
powders, but vibration will
dampen or stop when it becomes
buried in the measured materials.
2. Plug for VBL-12N/NT and VBL-
22N/NT
Screw to install the sensor to the
tank.
3. Flange forVBL-12F/FT,

• Principle of Operation
The vibration rod vibrates by installing piezo-electric element and
acceleration pickup mounted vibration board at the tip of the internal pipe. The
piezoelectric element provides vibration and the acceleration pickup detects
changes in the vibrational frequency. Covered with solids dampens vibration of
the vibration pipe. The electronic circuit detects the damping of these vibration
pipe. The electronic circuit detects the damping of these vibration and converts
into an relay output.
