Introduction
Applications
The device is used for level monitoring in all types of contai-
ners and silos.
It can be used with all powdery and granulated bulk materials,
slurry and liquids.
The units can be delivered with Ex-approvals for use in Dust
and Gas Hazardous Areas.
A selection of elds of application:
• Building materials industry
lime, moulding sand, etc.
• Food industry
sugar, our, salt, etc.
• Plastics industry
plastics granules etc.
• Chemical industry
pigments
• Mechanical engineering
The RFnivo is normally screwed into the lateral container wall
at a position, where the material shall be measured.
The device can also be mounted from the top of the container.
In this case an extension piece is used to mount the probe
level with the height to be measured.
The length of the probe can be up to 2.5 m (98.4”) with rod
extension or 20 m (787") with rope extension.
The use of a sliding sleeve is recommended so that the switch
point can be changed continuously during operation of the
device.
Function
The unit detects the capacitance between the probe and
the container wall.
The performance allows to use the unit in a wide range of
even difcult applications combined with simple handling:
• Active shield technology
The powerful active shield technology allows to ignore
material build up on the probe. Even the inuence
of conductive build up on the probe is electronically
compensated and thus ignored. This allows to measure
with high sensitivity in combination with material build up.
• Self diagnostics
The unit is able to check the internal electronic for proper
functionality. This can be done by setting a frequent auto
test or by pressing a manual test button.
• Auto calibration
The unit will auto calibrate to uncovered state after rst
time power up.
It allows to set for auto recalibration to uncovered state.
This is useful in case of a covered probe during power up.
An auto recalibration is done when the probe becomes
uncovered.
• Manual recalibration to uncovered state can be done by
simply pressing a push button.
• Full manual calibration can be selected as well.
The sensitivity is preselected to work in most applications
and can be changed if required.
