Guided radar level sensor for sterile containers and hygienic applications

The VEGAFLEX 83 guided radar level sensor is ideal for level and interface (separation layer) measurement in tanks or sterile containers in the food and pharmaceutical industry. With its bare stainless steel probe, it meets the highest standards of hygiene and is the perfect solution for all hygienically sensitive media. The high-quality stainless steel probe easily withstands aggressive or corrosive liquids. Measurement is completely independent of product properties such as density or temperature, as well as foam formation or build-up.

The VEGAFLEX 83 guided radar level sensor is a special probe for hygienically sensitive liquids, e.g. for:

Level measurement in a ketchup mixer
Level measurement in milk tanks
Level measurement in acid containers
