III. PRODUCT DESCRIPTION
FUNCTION
The LP®II Series units are electronic, vibratory level controls designed for use in powders and granular solids. A
vibrating “tuning fork” is used to sense the presence of material.
The tuning fork contains two piezoelectric crystal assemblies: one “transmit” and one “receive”. The Piezo
crystals convert electrical signals to mechanical movement, and vice versa. High-voltage DC is applied to the
transmit crystal cause the tines of the fork vibrate. This vibration is mechanically coupled to the receive crystal
which produces a small electrical signal. The receive crystal will produce low voltage as long as the fork is
vibrating.
If the fork stops vibrating, as it does when in contact with material in the vessel, the receive pulses stop. The
electronics recognize this loss of signal and cause the main relay to change state.
APPLICATIONS
Unlike radio frequency and capacitance technology sensors, the LP II Series devices sense material using a
mechanical principle and are therefore not aected by the dielectric constant of the material. These are ideal
sensors in plastics, dust, shavings, and low-density powders and food. Material as light as 0.5 lbs/ft3(8 kg/m3)
can easily be sensed. LP II can be used in any free owing dry material up to 3/8” (9.525 mm) in particle size.

IV. MECHANICAL INSTALLATION
WARNING: VERY HIGH VOLTAGE IS PRESENT ON THE FORK TERMINALS.
REMOVE POWER FROM THE UNIT BEFORE INSTALLING, REMOVING, OR MAKING ADJUSTMENTS
GUIDELINES
The following precautions should be observed when installing and operating an LP II device:
• The installation and wiring of this product must comply with all national, federal, state, municipal and
local codes that apply.
• The LP II Series are precision devices - handle carefully to prevent damage to the forks.
• Do not allow moisture to enter the electronics enclosure. Conduit should slope downward from the LP II
housing. Install drip loops (or drain tting) and seal conduit with silicone rubber product.
• The resonant frequency of the forks is 85 Hz (±10%); locations subject to this vibration frequency should
be avoided.
CAUTION: ATTEMPTING TO TIGHTEN THE UNIT BY ROTATING THE HOUSING OR FORKS MAY
DAMAGE THE UNIT AND VOID THE WARRANTY.
CAUTION: WHETHER MOUNTING DIRECTLY THROUGH A SIDE WALL, OR PIPE EXTENDED AND
MOUNTED VERTICALLY THROUGH THE TOP OF A VESSEL, NEVER ATTEMPT TO MOUNT THROUGH
A FULL COUPLING.
The LP II unit must be located at the position where level indication is desired. The forks may be mounted
through the top or side wall of the vessel. To ensure reliable operation, observe the following guidelines when
choosing the mounting location.
• DO NOT mount the forks in an area where they can contact the vessel.
• The forks assembly must be horizontal or pointing downward. DO NOT mount the forks pointing upward.
• If the unit is to be used with powders, it should be installed vertically, or at a downward angle that
exceeds the angle of repose to reduce material build-up on the forks.

CAUTION: THE MAXIMUM ALLOWABLE DOWNWARD FORCE ON THE FORKS IS 88 LBS 40 KG.
To calculate the maximum solids head height above a horizontally mounted fork, use the following equation:
Maximum height of material (ft) = 2200 / bulk density (lbs/ft3)
Do not mount the fork directly in the ow of material. If necessary, use a bae to protect the fork from falling
material. The bae should be placed 6 to 8 inches above the fork so that material will not become packed
between the fork and the bae.
If using a remote unit, remote turtle cannot be mounted more than 100 feet away.
Figure 2. Mounting In Relation To Flow of Material
If the fork is mounted horizontally, it must be positioned so that the material will not accumulate on top of the tines.
There is an index mark on the mounting nut to assist in proper positioning of the fork.
