Level sensors | Choosing the right level sensor
In all industrial processes that use reservoirs, silos or storage tanks, you need to know the level of the stored elements, or at least be able to detect significant levels (i.e. a full or empty tank). This is what level sensors and detectors are used for. Although these two terms might seem like synonyms, the two devices are fundamentally different: while a detector indicates whether the level has reached a certain height,  a sensor gives a continuous measurement...

How to choose this product
level-sensor

A level sensor measures the level of a liquid or loose, dry material in a container. It uses analog or digital technology to perform continuous, real-time measurements. Most are mounted vertically in the container.

Applications

These devices are found in every industrial domain for the continuous measurement of content levels.

Technologies

Measurement technology includes float, hydrostatic and capacitive systems. Non-contact measurements can be made using ultrasound or radar.

How to choose

Choice will depend on the material to be measured, whether liquid or a loose solid. Other factors include operating temperature and pressure, the characteristics of the container and the possible need for explosion protection.
