How Much Do You Know About Level Sensors? Let’s Find Out in This Article.
Level sensors are devices used to measure fill levels. They are particularly employed for the continuous measurement of the fill level of liquids and bulk materials. Broadly speaking, even a level limiting switch, which signals a specific fill height and triggers a reaction, is considered a level sensor.
In continuous fill-level measurement, the level sensor provides an analog or digital display of the measured values in various absolute and relative units. For instance, some sensors indicate the percentage value. It is also common for a fill-level sensor to output the value as voltage or current. Pressures, on the other hand, are displayed as a water column or in bar units. Conversely, in a level limiting switch, the value is generated via a switching contact.
Level Sensor Applications
The industrial applications for level sensors are practically endless. Fill-level measurements detect liquid and bulk material losses, prevent hazardous dry-running conditions, and help protect against explosions and system failures.
Advantages and Disadvantages of Level Sensors
A level sensor can be an extremely precise measurement tool. However, it is essential to choose the right sensor since some measurement techniques are highly sensitive to dust or impurities in the measured medium. Certain types are very easy to install, as they can operate even behind the walls of containers. In general, the wide variety of technological solutions for fill-level measurements ensures there is a suitable option for every use case.
Level Controllers: What Are They?
Level controllers are devices designed to send commands to regulate the level of liquids in tanks or wells.
