Bladed level gauges PFG-86
00625 97.06 - Rev. 05
The PFG-86 level gauge is made in compliance with the regulations in force in the European Union and specifically with:
- Die-cast aluminium casing UNI 5076. IP65 protection.
- Stainless steel shaft on ball bearings, watertight with permanent lubrication, with neoprene Corteco ring for dust sealing.
- Standard Nylon screw, on request made of stainless steel or other materials and versions with 1, 2, 3 or 4 blades.
- Electrical construction in compliance with Directives 2014/35/EU (low-voltage electrical material) and 2014/30/EU (electromagnetic
compatibility).
- Output speed (screw shaft): 1rpm.
SAFETY RULES
All the appropriate safety precautions must be taken when electrically operated equipment is used, in order to reduce
the risk of fire outbreaks, electric shock and injuries to persons.
- Keep the work zone clean and orderly. Accidents are more likely to occour in untidy areas and environments.
- Before beginning work, make sure that the level gauge is in a perfect condition. Damaged or broken parts must be
repaired or replaced by competent personnel authorized by the Manufacturer.
- All verifications, inspections, cleaning and maintenance operations, part changes and replacements must be carried
out with the level gauge disconnected and the plug removed from the power socket.
- It is absolutely forbidden for children, unauthorized and/or inexpert persons to touch or use the level gauge.
- Make sure that the electricity system complies with the laws in force. Make sure that the earthing is efficiently
connected when the instrument is installed. Check to be sure that the power socket is suitable, that it complies
- The level gauge must never be stopped by detaching the plug from the power socket. Moreover, never use the
cable to pull the plug from the socket.
- Periodically check to be sure that the cable is in a perfect condition and replace it if damage is discovered.
This operation must only be carried out by competent and authorized persons. Only use extensions cables of the
- Protect the cable against high temperatures, lubricants and sharp edges. Do not twist or knot the cable.
- Do not allow children or unauthorized persons to touch the cable when the instrument is plugged in.
Before installation, inspect the outer structure of the level gauge. Check the movement of the screw shaft and
the operation of the clutch assembly. If this check reveals anything irregular, the level gauge must be sent to
CAMLogic to be restored to efficiency. CAMLogic level gauges can be installed in any position. With the shaft in a

be mounted with the wiring plate inside the casing
in an upright position and the cable passages on
the right-hand side ( Fig.1 ).
The level gauge is mounted on the chambers or
silos, on the side or top.

permitted type and marked.
The level gauge can be mounted on the silos by the standard connection with threaded sleeve ( 2" 1/2 Gas ) to be
welded onto the silos ( PFG-86 ) or by flange connection with 6MA screws ( PFG-86/F ). These two methods involve
around the gauge. Protective deflectors ( Fig.2 )
are advisable when there is considerable weight
no modifications to the level gauge since the flange uses the thread on the body of the gauge envisaged for the
sleeve. When mounting with the sleeve, the gauge must be fully screwed onto the sleeve, then it is necessary to
turn it to obtain an upright position of the wiring plate, then tighten the securing screw on the threaded sleeve.

The conductors forming the power supply and signal carrying cable must have an adequate cross-section so that
the current density, in each conductor, is no higher than 4 A/mm². One of these is used only for the earthing of
the level gauge. The cross-section of the conductors must also be adequate in relation to the length of the cable
used to avoid a drop in voltage along the cable over the values prescribed by the regulations on the subject.
It is likewise reccomended to use flexible cables with an adequate outside diameter for the cable entries used
( not supplied ) to ensure a perfect seal of the cable clamp on the power supply and signal carrying cable.
CAUTION : The terminal box contains a screw whose position is marked by the
symbol made in the casting ( Fig.3 ) which has the function of making the ground
connection for the level gauge. This screw must be connected to the yellow-green
conductor ( only green for the USA ) of the power cable. The ground connection of
the level gauge, through the yellow-green conductor, is compulsory.
By the terminal box there is the wiring plate ( Fig.1 ) which has printed on it the
that the mains voltage and frequency correspond to those given on the plate of the level gauge before powering up.
CAMLogic level gauges need no routine
maintenance. Possible extraordinary maintenance
is restricted to replacing parts that are
deteriorated by use.
The gauge must not be lubricated; the shaft,
the only moving part, is mounted on ball
bearings with permanent lubrication.

CAMLogic, in addition to the terms of the supply
contract, guarantees its products for a period
of twenty-four ( 24 ) months from the date of
shipment. This warranty is expressed only in the
repair or replacement free of charge of parts that,
after careful examination by the Manufacturer,
turn out to be defective.
Warranty, excluding all liability for direct or
indirect damage, is considered to be restricted
to only defects in materials and has no effect
if the parts returned turn out to have been
anyhow dismantled, tampered with or repaired
by anyone other than the Manufacturer.
Warranty likewise excludes damage deriving
from negligence, carelessness, bad or improper
use of the level gauge, or from bad handling
by the operator and faulty installation.
Warranty is moreover forfeit if non-genuine
spare parts have been used.
A returned level gauge, even if under
warranty, must be shipped carriage free.
All the information contained in this manual is confidential and no
part of it may be disclosed without written authorization from CAMLogic.
