Level Sensors - SICK

Level sensors in automation detect liquids, powders and granules in tanks, hoppers and machine reservoirs. They prevent overfills, protect pumps from running dry and keep material supply steady for production.

Level Sensor Types

• Capacitive level sensors – detect through non-metallic tank walls
• Ultrasonic level sensors – non-contact continuous measurement
• Optical level sensors – compact point detection
• Float and vibrating sensors – simple, reliable switching
• Guided wave sensors – continuous level in small tanks

Choosing a Sensor

Consider the media, tank material, mounting space and whether you need point or continuous measurement. Foam, buildup and turbulence affect some technologies. IO-Link sensors provide extra diagnostics.

Centro supplies level sensors for machine and process automation.
