New potentiometric sensor raises the bar for level measurement

The latest IO-Link sensor from Baumer is the CombiLevel PLP70 level sensor, meeting the needs of applications with high grade diversity and frequent media changes such as those occurring in the beverage, brewing and other similar liquid handling processes.

The key benefits of this potentiometric sensor are to make continuous level measurement easier and more flexible, including the ability to automatically adapt to a wide range of media. Typical applications include precise monitoring of process levels in feeding containers, storage and buffer tanks and fast changing levels in filling lines.

One of the most important features of the PLP70 sensor is its ability to measure very low minimum conductivity media. For example, previous sensors were able to measure media with a conductivity starting at 50 microsiemens/cm whereas this new option will detect extremely low conducting media starting at 5 microsiemens/cm. This pushes the conventional limits of these sensors and allows for use in media such as process water.

Thanks to its media-independent measuring principles, the PLP70 sensor ensures ultra-high precision and repeatability even in the most demanding applications which involve low-conducting, pasty, adhering or foaming media which are difficult to measure with less advanced sensors. The sensor also provides short response times of less than 100 milliseconds and this, combined with ultra-high precision, helps to maximise process efficiency.

Operators will also appreciate the easy monitoring and control of the sensor via the proven Baumer display which includes a background changing colour and effectively provides all the required information at a single glance, even from longer distances. Functions of the touch display include temperature, pressure and conductivity enabling quick and convenient operator intervention directly at the sensor display.
