III. PRODUCT DESCRIPTION
FUNCTION
The LP
®
II Series is an electronic, vibratory level control designed for use in powders and granular solids. A vibrating rod is
used to sense the presence of material.
The rod contains two piezoelectric crystal assemblies. The Piezo crystals convert electrical signals to mechanical
movement, and vice versa.
When material comes in contact with the rod it will cause a reduction in the level of vibration. If the reduction of the
vibration is greater than the set threshold determined by the sensitivity setting the alarm relay will turn ON or OFF
depending on the fail-safe settings.
APPLICATIONS
Unlike radio frequency and capacitance technology sensors, the LP II Series devices sense material using a mechanical
principle and are therefore not affected by the dielectric constant of the material. These are ideal sensors in plastics, dust,
shavings, and low-density powders and food. The rod is more often used in larger size materials such as gravel or pellets.
FEATURES
Universal input power; AC or DC (see specifications for input ranges)
