Tank cap monitoring Cheeseproduction
Inductive fail-safeproximity switch
category 4 detectsthe stainless steeltank cap without
contact and
without any specific
counterpart (man-hole monitoring).
Thecompany In cheese produc-tion the use of
aggressive cleaningagents is very com-mon. The photo-
electric sensors
need to be abso-lutely ingress-resis-tant in these condi-
tions.
A group of valves iscommonly called avalve matrix. Valvematrices make it
possible to distrib-
ute the product
between differentparts or blocks. Dueto their compact
design they require
little space. AS-interface is used toindicate valve
position and to
control the valves.
General
information Proximity switches Pneumatically-operated actuators
(quarter-turn) for
the automatic trig-gering of butterflyvalves. Inductive
dual sensors type
IND are used for
position feedback. Types GG, GI, GM

The transparentmaterial PET is usedmore and more
often in the bever-
age industry. In the
past the adjustmentof the sensors tothe application was
very complex. A
new system of
retro-reflective sen-sors with polarisa-tion filter (type OJ
PET) with a very
fine prismatic
reflector is used
here.

Inductive proximity switcheswith IP 69 K in M8, M12, M18, M30
and smooth housing. Due to limitedspace compactphotoelectric sen-
sors are used to
detect the position
on bottling andpackaging machi-nes in the beverage
industry. See page 14-19
Flowsensors These valves areactuated by a linear
stroke. Inductiveproximity switches(standard solution)
or efector valvis are
used for position
feedback.
Pneumatic cylindersare used in manyareas of the food
industry. To meet
the high require-
ments special ifmcylinder switcheswith the high posi-
tion rating IP 69 K
are used to sense
the position ofpistons.
