Non-ferrous metal detection for food industry

What is the difference between a non-ferrous and a ferrous detector There is a difference between non-ferrous and ferrous products to be identified

Any steel can make ferrous products

Non-ferrous Products: Any metal, except steel (brass or copper, etc.).

Attention, non-ferrous doesn’t necessarily mean all materials (wood, plastics, etc.). It refers to metals

There is a difference between non-ferrous and ferrous sensors

Sensors can detect:

Preference for ferrous metals (steel, Iron)

These products have different sensing distances. Maximum for ferrous metals. Km coefficients are typical for each metal. Km = 1 for Steel.

This coefficient decreases the sensor detection range. Km = 1. For cast iron, but only 0.25 for for copper.

This is the traditional inductive sensor

Non-ferrous metals (steel, iron, etc.) as well as ferrous (steel and iron). Metals

These sensors can sense both ferrous and nonferrous materials at the same distance. Km coefficient is always 1.

These sensors are known as Ferrous/Nonferrous sensors.

Schneider part numbers are XS1M18KPM40x and XS1M30KPM40x 18- and 30-diameter sensors, respectively, and XS7C40KPM40x40x

Choose from ferrous or non-ferrous materials

Schneider part numbers: XS1M18PAS40x sensitive to ferrous materials, and XS1M18PAS20x sensitive to non-ferrous substances

These sensors are known as selective ferrous/non-ferrous sensors.
