Industrial Applications

1. Liquid Level Detection in Chemical Processing

This sensor can accurately detect the presence or absence of liquids, including aggressive chemicals, within non-metallic tanks or through sight glasses. Its 4mm flush sensing distance and adjustable sensitivity allow for precise level control without direct contact.

Problem Solved

Prevents overfilling or underfilling of tanks containing corrosive or hazardous liquids, ensuring process safety and efficiency. The stainless steel (AISI 316L) housing and PEEK sensing face provide excellent chemical resistance, and the IP65 rating ensures protection in washdown or harsh chemical environments.

2. Granular Material Detection in Food & Beverage Packaging

Ideal for detecting granular materials like sugar, flour, or coffee beans in hoppers, chutes, or packaging lines. Its suitability for foodstuff conditions and robust construction make it perfect for hygiene-critical applications.

Problem Solved

Ensures accurate material flow and prevents blockages or empty containers in packaging processes. The ability to detect non-conductive materials and the IP65 rating for washdown, combined with food-grade materials (stainless steel, PEEK), address the strict hygiene requirements of the food industry.
