Balluff's new SmartLevel sensors provide accurate level detection in demanding applications where extensive foaming, filming, and material build-up are present. Capacitive sensors are used for level indication of a wide variety of materials, ranging from dry bulk materials - such as powders and granulate - to liquid compositions. Liquids impose special difficulties for level sensors in general, since some tend to foam, whereas others are adhesive or create material build-up on the sensors or container walls.
A sensing technology described as 'groundbreaking' enables SmartLevel sensors to distinguish reliably between true liquid level and foam, film, or build-up that would cause conventional capacitive sensors to give a false trigger.
SmartLevel sensors are only suitable for water-based liquids or other highly conductive liquids. They automatically tune-out plastic or other non-conductive wall materials without teach-in procedures or other user interaction, thereby reducing the assembly time and simplifying set-up routines.
Available in a wide range of housing shapes and materials including M18 and M30 in PVC or PBT housings; cPTFE models offer complete PTFE housing and cable in M18, M30 and 50mm diameter housings that are suitable for use in harsh chemical environments.
