Level sensors play a key role in many industrial applications, serving to monitor the level of various media, from liquids to bulk materials. There are various technologies available for this purpose, and among the most common are vibration and capacitive level sensors. In our experience, in many industrial applications it is more advantageous to use a compact capacitive sensor for level measurement. In this blog post, we discuss the principles of both devices, fairly compare their advantages and disadvantages, and share tips on which technology to use for specific applications. Read on and choose the right liquid and bulk level sensor!
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.
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.
The JUMO ZELOS C01 (408401) capacitive level sensor has an LED that lights up in as many as 5 colors to indicate the event assigned to a particular color.
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.
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 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.
