Installation Hints
Capacitive sensors have the
unique ability to detect al-
most all materials, either in li-
quid or solid form. Capacitive
sensors can detect metallic
as well as non-metallic ob-
jects, however, their tradition-
al use is for non-metallic ma-
terials such as:

Cleansers, fertilisers, liquid
soaps, corrosives and
petrochemicals.
• Packaging Industry
Package inspection for
level or contents, dry
goods, fruits and vege-
tables, dairy products.

Technical Information.
• Semi-conductor Industry
• Food & Beverage
Materials are detected due
to their dielectric constant.
