Point level detection with capacitive measurement technology

Capanivo® capacitive level switches are universally applicable in bulk solids, granulates, powders, liquids, highly viscous oils, slurries and pastes as full detectors, overfill protection, demand or empty detectors, as level switches or for interface measurement in mixers, silos, tanks, process vessels, hoppers, troughs as well as channels and pipelines. Due to different device versions, installation situations from above, below, the side or with little space requirement can be realized. Further the capacitive sensors of the Capanivo® CN 7000 and CN 8000 series can be used for single media detection (e.g. when foaming) or as sensors for leakage detection.

The robust sensor tip made of fiberglass-reinforced plastic is suitable for use in foodstuffs as well as being resistant to aggressive chemical media. The Capanivo® can be used in storage tanks, silos and process vessels or also in pipes as a level switch, back pressure detector, as dry run protection or as a valve control.

As a capacitively measuring sensor it reacts with a change in capacitance when the sensor tip is touched by a solid, liquid or foaming medium and then switches a signal output (relay or transistor). The versions for solids additionally have active lug compensation due to the built-in Active Shield technology ensures reliable functionality within applications with foam, bridging, material deposits, caking or other types of buildup properties. 

In addition to WHG or SIL 2 approval, the various sensors in the Capanivo® series also have international approvals for gas and dust explosion hazardous areas. This makes them the ideal solution for most industries when it comes to level monitoring.


FAQ – Capanivo® LEVEL MEASUREMENT

› When is the Capanivo® the right solution for capacitive point level detection?

The Capanivo® is the right solution when point levels in bulk solids or liquids need to be monitored reliably. It is suitable for full, empty and demand detection, overfill protection and, depending on the version, for applications such as dry-run protection, leakage detection and interface measurement. Typical installation points include silos, tanks, process vessels, pipelines, hoppers and mixers.

› Which media is the Capanivo® capacitive sensor suitable for?

The Capanivo® is suitable for bulk solids, granules, powders, liquids, highly viscous oils, pastes, slurries and foams. Depending on the sensor version, it can reliably detect a wide variety of media across numerous industrial applications.

› What are the advantages of a Capanivo® capacitive level sensor?

The Capanivo® features a robust design, versatile installation options and easy integration into a wide range of process plants. Depending on the series, international hazardous area approvals, SIL 2, WHG approval and various versions for demanding applications are available.

› Can the Capanivo® also measure reliably in applications with material build-up or foam?

Yes. The versions for bulk solids are equipped with Active Shield technology. This compensates for material deposits and build-up on the probe, ensuring reliable point level detection even under demanding conditions. Special device versions are also available for applications involving foam or specific media detection.
