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 aected 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 specications for input ranges)
No calibration required
Adjustable time delay
Selectable fail-safe operation (high or low level)
Adjustable Sensitivity

IV. MECHANICAL INSTALLATION
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 rod.
• 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 rod is 400 Hz (±10%); locations subject to vibration frequencies greater than 100
Hz should be avoided.
CAUTION: WHEN MOUNTING UNITS, NEVER ADJUST THE ORIENTATION BY TURNING THE HOUSING. USE A
WRENCH FOR PROCESS FITTING UNITS, OTHERWISE A STRAP WRENCH SHOULD BE USED TO TIGHTEN INTO PLACE.
ATTEMPTING TO TIGHTEN THE UNIT BY ROTATING THE HOUSING OR ROD 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.
WARNING: HIGH VOLTAGE IS PRESENT. REMOVE POWER FROM THE UNIT BEFORE INSTALLING, REMOVING, OR
MAKING ADJUSTMENTS.
WARNING: IN ORDER TO MAINTAIN SAFE OPERATION IN HAZARDOUS LOCATIONS, THE INTEGRITY OF THE
ALUMINUM CASTING AND THE ENVIRONEMENTAL SEALS MUST BE MAINTAINED. THE USER/INSTALLER
MUST AVOID INSTALLATIONS WHERE AGGRESSIVE SUBSTANCES MAY BE PRESENT AND COULD AFFECT THE
PERFORMANCE OF THESE MATERIALS. CARE MUST ALSO BE EXERCISED WHEN REMOVING AND REPLACING THE
COVER, SO NO MARRING, SCRATCHING OR DAMAGE OCCURS TO THE FLANGES, AND THAT FLANGE SURFACES
REMAIN COMPLETELY CLEANED OF DEBRIS.
WARNING: FOR UNITS INSTALLED IN HAZARDOUS LOCATIONS, TO REDUCE THE RISK OF IGNITION OF HAZARDOUS
ATMOSPHERES, CONDUIT RUNS MUST HAVE A SEALING FITTING CONNECTION WITHIN 18 IN. OF THE ENCLOSURE.
WARNING: FOR PRODUCTS MARKED AS TYPE 4X, USE TYPE 4X HUB FITTING; FOR IP66 USE IP66 HUB FITTING.
GUIDELINES
6LVP180914 Rev. D
www.bindicator.com
The LP II unit must be located at the position where level indication is desired. The unit 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.
If using a remote unit, remote turtle cannot be mounted more than 50 feet (15m) away from the probe.
DO NOT mount the unit in an area where the rod can contact the vessel.
The assembly must be horizontal or pointing downward. DO NOT mount the rod 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 (see gure 1).
Figure 1. Mounting Orientation
Do not mount the rod directly in the ow of material. If necessary, use a bae to protect the rod from falling material. The
bae should be placed 6 to 8 inches (15 to 20 cm) above the rod so that material will not become packed between the
rod and the bae (see gure 2).

CAUTION: THE MAXIMUM ALLOWABLE DOWNWARD FORCE ON THE ROD IS 700 IN. LBS.
CAUTION: PROPER AND SAFE OPERATION REQUIRES THE UNIT TO BE SECURELY MOUNTED TO THE VESSEL AND
WRENCH TIGHTENED. THE COVER MUST BE PROPERLY INSTALLED WHEN POWER IS SUPPLIED.
