Functionality
A bellow monitor can be operated with both the
DS and LW systems. By default, both installations
require the use of blind covers for a connection on
the housing / flange and the connection of a level
container to the other connection. During commissioning, the container of the system is filled with
pure glycerine up to a defined level. Through the
actuation of the valve, the volume inside the internal assembly is displaced.

Design Characteristics
-t Visual status display in the container via LED
-t Yellow LED = System OK
-t Blue LED = System alarm
-t Class of protection IP65
-t Adjusted container size for all GEA Aseptomag
valve types and nominal diameters
-t The level container is sealed against the atmosphere in an air-tight manner
-t Air compensation in the level container takes
place via a folding bellow

This volume is taken up in the level container and
monitored with a magnetic float switch. If leakage
occurs in the bellow and product penetrates the
system, the level in the container rises. If leakage
occurs in negative pressure conditions, the glycerine
level in the level container drops. In both cases,
bellow monitoring electronics trigger an alarm and
sends it to the PLC.

Installation
-t Valves that have either the DS or LW system can
be retrofitted at any time
-t The base plate of the bellow monitor may be
mounted directly to the pneumatic actuator or
between the actuator and the feedback unit
The use of the bellow monitoring system does not
preclude the use of a valve feedback unit
-t The level container can be disassembled without
the electronics having to be removed from the
valve
