Capacitive Level Limit Switch

Capacitive level sensors measure the level of a medium in a tank by observing changes in capacitance. As the level of liquid or other medium in the tank increases or decreases, the capacitance changes. This sensor converts this change into a signal that displays the current level of the medium.

Applications of Capacitive Level Limit Sensors

Capacitive level sensors are commonly used in the food, chemical, agricultural, and beverage industries. Due to their accuracy and versatility, they are ideal for monitoring the level of liquids, pastes, suspensions, and bulk materials.

Vibrations-Füllstandssensor - Funktionsprinzip

Vibrations-Füllstandssensoren, die oft auch als Resonanzsensoren bezeichnet werden, arbeiten nach dem Prinzip, dass sie die An- oder Abwesenheit eines Mediums durch Veränderung der Schwingungen im Inneren des Sensors feststellen. Hauptbestandteil eines solchen Sensors ist ein Nockenstein oder ein anderes Vibrationselement, das Schwingungen mit einer bestimmten Frequenz erzeugt. Wenn das Medium das Vibrationselement berührt, ändert sich seine Schwingungsfrequenz. Diese Änderung wird dann erfasst und verarbeitet, um den Füllstand des Mediums zu bestimmen.

Anwendungen von Vibrations-Füllstandssensoren

Vibrations-Füllstandssensoren werden häufig in der chemischen Industrie, im Baugewerbe, in der Landwirtschaft und in der Lebensmittel- und Getränkeherstellung eingesetzt. Sie werden dort eingesetzt, wo eine genaue und zuverlässige Füllstandüberwachung von Schüttgütern, Pulvern, Granulaten oder Flüssigkeiten erforderlich ist.

Capacitive vs. Vibratory Level Sensors - Comparison

Construction and Operation:

• Capacitive level sensors work on the principle of capacitance change in response to the presence of a medium.
• Vibratory level sensors operate based on vibrations, the change of which is detected when in contact with the medium.

Applications:

• Capacitive level sensors are versatile and can be used for both liquids and solids. The JUMO ZELOS C01 capacitive level limit switches, with their Teflon measuring element, are also optimal for food applications.
• Vibratory level sensors are particularly effective in detecting solid and liquid media, even in challenging conditions such as turbulence or strong external vibrations.

Benefits:

• Capacitive level sensors are characterized by a compact design and streamlined shape. Additionally, the JUMO ZELOS C01 capacitive sensors are made of materials safe for use in the food industry and feature foam detection.
• Vibratory level sensors offer durability.

Price:

• Capacitive level sensors often have a significantly lower price compared to vibratory level sensors.

Limitations:

• Vibratory sensors may have limitations in certain applications, for example in the food industry, where there is a risk of contamination due to the possibility of material accumulation.
• Capacitive sensors may require more precise configuration in specific applications and can be sensitive to extreme environmental conditions.

Vibrating level sensor vs. capacitive boundary level sensor – summary

Capacitive level sensors are versatile and can be used for both liquids and solids. JUMO ZELOS C01 capacitive level beacons, due to their measuring tip made of PEEK material, are also optimal for food applications.

The choice between vibration and capacitive level sensors depends on the specific application and requirements. In some cases, a vibrating sensor may be a better choice due to its robustness, while in other situations a capacitive level sensor may be more suitable due to its versatility and cost advantages.
