Capacitive Smart Level Sensors in Block-style Housings – Now also with IO-Link

Ideal level measurement sensors for foaming or adhesive media

Anyone who has ever tried detecting the level of strongly foaming, conductive liquids using conventional capacitive sensors knows how difficult this is. The solution is compact capacitive Q40 sensors with Smart Level technology from Balluff. Thanks to patented pulse technology liquid films or dirt buildup inside or outside the container do not affect the measuring result. Brand new in the range is a version with IO-Link. This offers the user additional features and setting options.

For these non-contact sensors using Smart Level 50 technology non-metallic walls up to 6 mm thick are no problem. They automatically compensate for the wall as well as for foam and build-up. In standard applications this eliminates cumbersome adjustments. Users can count on precise measuring results even with highly conductive or aggressive media. No more regular sensor and container cleaning is required.

Thanks to the IO-Link interface users of the new version enjoy expanded application and setting options. The sensor is easy to install using industry standard 3-conductor cable. You can also position the sensors in the machine directly at the location of operation access to the sensor is no longer critical. Process monitoring, configuration and error analysis of the IO-Link sensors take place in the controller and over the IO-Link interface. The sensor can be operated in either standard I/O or IO-Link m ode. The switching point as well as the output configuration (factory set to PNP normally open) can be easily changed over IO-Link.

The rugged, time-tested PBT housings and IP 67 protection of the Smart Level sensors with dimensions of 40 x 40 x 10 mm can be easily installed using screws, brackets or simply using cable ties. Cable ties are particularly practical on pipes and tubes, since no adjustable mounting brackets or time-consuming adjustment are necessary. Two colored LEDs indicate the ready state and switching status.
