Product Description

The SICK UP56 Ultrasonic Level Sensor is a non-contact industrial level measurement device designed for continuous monitoring of liquids and bulk materials.

It uses ultrasonic echo technology to provide stable and reliable level detection even in challenging conditions such as aggressive media, viscous liquids, or dusty bulk solids.

With multiple output options including analog signals and IO-Link communication, the UP56 is widely used in industrial automation systems where accurate tank level measurement sensor performance is required.
