Adjustment Guide

The environments in which
capacitive sensors are install­ed can often be un

stable re­garding temperature, humidity,
object distance and industrial
(noise) interference. Because
of this, Carlo Gavazzi offers as
standard features in all TRIP-
LESHIELD™ capacitive sen­sors a user-friendly sensitivity
adjustment instead of having
a fixed sensing range, extend­ed sensing range to accom-

modate mechanically demand­ing areas, temperature stability
to ensure minimum need for
adjusting sensitivity if temper­ature varies and high immuni­ty to electromagnetic interfer­ence (EMI).

Note:

Sensors are factory set
(default) to maximum rated
sensing range.

Output

Capacitive sensors have the
unique ability to detect al­most all materials, either in li­quid or solid form. Capacitive
sensors can detect metallic
as well as non-metallic ob­jects, however, their tradition­al use is for non-metallic
materials such as:

Resins, regrinds or mould­ed products.

• Chemical Industry

Cleansers, fertilisers, liquid
soaps, corrosives and pe­trochemicals.

• Wood Industry

Materials are detected due to
their dielectric constant. The

the higher the density of ma­terial, the better or easier it is
to detect the object. Nominal
