3. Level Detection of Opaque Liquids in Small Industrial Tanks

Leveraging its adjustable reflective sensing and chemical resistance, this sensor can monitor high or low levels of opaque liquids in small industrial tanks or reservoirs without direct immersion. The 20-300mm range provides flexibility for mounting above the liquid surface.

Problem Solved

Automates liquid replenishment or prevents overfilling/underfilling, providing critical level control in applications where chemicals like ethanol, oils, or coolants are used, and where the sensor needs to withstand splashing or corrosive vapors.
