Introduction
The Nivobob®NB 3000 is an electromechanic level measuring
instrument for continuous measuring of level or volumes in silos,
hoppers or tanks.
Applications
• Powder, granulate, small or coarse bulk goods
• Interface measurement (solids in water)
Applicable for industries such as
• Chemistry
• Food
• Cement
• Mining
• Plastics
• others
Features
Process
• Suitable for most types of bulk goods
• Independent of bulk material properties, such as:
Dielectricity and conductivity of the bulk good
Dusty atmosphere in the silo
Changing humidity inside the product
Products that tend to stick
• No mechanical load on the silo roof, the sensor weight
just touches the surface of the material
• Very accurate measurement
Service
• Simple installation and commissioning
• Measurement principle easy to understand
• Rope, tape and (optional) motor with increased service life
• Low maintenance
Approvals
• Approval for use in Hazardous Locations
ATEX II 1/2 D (zone 20/21) and FM Class. II, III Div.1 Gr. E-G
Mechanic
• Measurement range upto 40m (133ft)
• 1 1/2" process connection possible
• Different sensor weights, suitable for every application
• Internal tape cleaner for difficult materials
• Window in lid and external start button (optional)
• Robust cast housing, ingress protection IP66
Electronic
• Micro processor controlled measurement
• Remote Box for external programming, display of level and
diagnose, start of measurement of up to 10 Nivobob units
• Comprehensive Diagnose possibilities
• Output 0/4-20mA / Modbus / Profibus DP / counting pulses
• Programmable relais (can be used as level limit switch outputs)
• Measurement start with external signal or integrated timer
Function
The Nivobob® NB 3000 is mounted on the top of the silo. A sensor
weight is driven down into the silo. It is mounted at the end of a rope
or tape which is wound on a motor driven roller. Upon contact with
bulk material, the motor changes the winding direction and the sensor
weight is driven back to the upper stop position.
During downwards movement of the sensor weight the distance is
electronically measured by the rotations of the internal rope / tape
roller. The microcontroller converts the measured distance into an
output signal, which is a volumetric signal based on the silo geometry.
The output signal is updated, when the sensor weight touches the bulk
material.
Diagnostics
Comprehensive diagnostics possibilities are present:
• Measurement control is done by comparing the moved distance
between up and downward movement and checking for discrepancy.
In case of discrepancy, the sensor weight is pulled to the upper stop
position to ensure, that the sensor weight is not inside the silo.
• Service interval after a certain amount of measurements and running
time.
• Internal control of motor, motor driver electronic and smooth
movement of rope / tape rollers.
Diagnostics is in accordance with NAMUR recommendation NE107.

General Safety Instructions
Process pressure Improper installation may result in loss of process pressure.
Chemical resistance
against the medium
Materials of construction are chosen based on their chemical compatibility (or inertness) for general purposes.
For exposure to specic environments, check with chemical compatibility charts before installing.
Mounting location The right mounting place is significant for a proper function. Observe mounting instructions.
Vibrations Avoid mounting in applications with strong vibration. Use rubber mounts for absorption in case of light
vibrations.
Mounting instructions
Mounting position • The unit is mounted vertically on the silo. Max. deviation is 2°.
• There must be at least 200mm (7.87“) space for the sensor weight to move down in case of a full silo.
Observe the bottom of the sensor weight at "upper stop position" (dimensions see page G4 - G6).
Additional Safety Instructions for Hazardous Locations
Installation regulations For devices to be used in Hazardous Locations the respective valid installation regulations must be observed.
Sparks The installation has to be done in a way, that mechanical friction or impact does not cause sparks between
the aluminium enclosure and steel.
• The socket pipe of the unit must
protude at least 50mm (2") into
the silo. A version with longer
socket pipe is available.
• Proper movement of the sensor weight must be
guaranteed, even if the sensor weight oscillates.
Observe enough distance to the silo wall, stanchions
and built-in fittings.

Mounting
Measurement during filling
of the silo
Filling of the silo while measuring might cover the sensor weight with bulk material. Measurements during filling
are possible, if there is enough distance to the infeed, so that no material can fall on the sensor weight.
Sensor weight
"Bag" and "Float"
• The weights are lled with plastic granulate or sand. They shall be lled on site with bulk material or liquid,
which is not critical if mixed with the material stored in the silo. Consider ageing of the material.
• When lling, observe the total weigth of the sensor: rope version 1.0kg (2.2lbs), tape version 2.1kg (4.6lbs)
Sealing • A rubber seal must be used to tighten the ange.
• Close both lids of the enclosure tightly.
Sensor weight which
does not fit through
the mounting hole
The sensor weight must be removed before
placing the unit on the silo. An inlet close to the fixing
loacation and a hook is needed.
See installation manual for more details. Hook

Electrical installation
Handling In case of improper handling or handling malpractice, the electric safety of the device cannot be guaranteed.
Installation regulations The local regulations or VDE 0100 (Regulations of German Electrotechnical Engineers) must be observed.
Fuse Use a fuse as stated in the connection diagrams.
RCCB protection In case of a fault, the supply voltage must be automatically switched off by a RCCB protection switch to
protect against indirect contact with dangerous voltages.
Power supply switch A voltage disconnection switch must be provided near the device.
Wiring diagram The electrical connections are made in accordance with the wiring diagram.
Supply voltage Compare the supply voltage applied with the specifications given on the name plate before switching the
device on.
Cable gland Make sure that the screwed cable gland safely seals the cable and that it is tight (danger of water intrusion).
Cable glands that are not used have to be sealed with a blanking element.
Conduit system In case of using a conduit system (with NPT thread) instead of a cable gland the regulations of the country,
where the unit is installed, must be observed. The conduit must have a tapered thread either NPT 1/2“ or
NPT 3/4” in accordance with the unit and ANSI B 1.20.1. Not used inlets must be closed tight with a metal
blanking element.
Field wiring cables All field wirings must have insulation suitable for at least 250V AC. The temperature rating must be at least
80°C (176°F).
Relay protection Provide protection for relay contacts to protect the device against inductive load surges.
Protection against static
charging
The housing of the unit must be grounded to avoid static charging of the unit. This is particularly important
for applications with pneumatic conveying and non-metallic containers.
General Safety Instructions
External equipotential
bonding terminal
Field wiring A strain relief must be provided for the eld wiring cables, if the device is installed with the factory provided
cable glands.
Cable glands for ATEX
Hazardous Locations
The used entry devices and blanking elements must have an adequate type approval and a temperature
range as defined in the technical data of the unit. In addition they shall be suitable for the conditions and
correctly installed. Where applicable the provided original parts of the manufacturer must be used.
Conduit system for
ATEX and FM
Hazardous Locations
In addition the regulations of the country must be observed. The used flameproof seals and blanking
elements must have an adequate type approval and a temperature range as dened in the technical data
of the unit. In addition they shall be suitable for the conditions and correctly installed. Where applicable the
provided original parts of the manufacturer must be used.
Comissioning / opening the
lid
Comissioning only, when there are no dust deposits or swirls present.
Additional Safety Instructions for Hazardous Locations
Connect to equipotential
bonding of the plant
