Installation and Maintenance Rules for:
Bladed level gauges for high temperatures
PFG-86/AT
STANDARD FEATURES
The PFG-86/AT 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 FPM 75 Corteco ring for dust sealing.
- Standard stainless steel screw, on request different 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).
- Noise level measured in open field: zero.
- Motor absorption: 4 Watts.
ATEX MARKING: II 1/2 D Ex ta/tb IIIC T85°C Da/Db
II Group II, intended for use in surface industry.
1/2 D Suitable for Cat. 1 - Zone 20 inside silos (shaft with screw); Cat. 2 – Zone 21 external (indicator casing).
Ex ta/tb Protection method Ex t - protected against dust (ta internal / tb external).
IIIC Dust group C (suitable for operation in presence of all types of dust, conductives included).
T85°C Temperature class - maximum superficial temperature of the device 85°C.
Da/Db Equipment Protection Level for dust atmospheres. Da (very high) for zone 20 (internal); Db (high) for zone 21 (external).
VERSIONS
Level gauge PFG-86/AT is produced in three main versions:
PFG-86/AT/F - with flange connection.
The metal parts of the gauge are insulated from each other by heatproof material with characteristics suited to the operating
temperatures. All other parts in contact with the product are made of stainless steel. On request, the gauge can also be
made of a different heatproof material with insulating specifications able to withstand higher than standard temperatures.
In particular, level gauge PFG-86/AT/F/V is suitable for operation in places and with materials with a high degree of humidity
and in presence of steam. The particular structure, with double flange connection, allows the condensation to be drained off.
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
with the laws in force and that it has a build in automatic protection circuit-breaker.
- Make sure that the surface temperature of the level indicator casing does not exceed the specifications on the nameplate.
- 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 is damaged. This operation must
only be carried out by competent and authorized persons. Only use extensions cables of the permitted type and marked.
- 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.
INSTALLATION
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 gauge can be installed in any position.
With the shaft in a horizontal or sloping position, the level
gauge must 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. It is important
to choose the position so that the device is not hit by
the falling load, likewise taking care that the material can
move freely all around the gauge. Protective deflectors
