DESCRIPTION:
GENERAL INFORMATION
The pressure gauge installed on the machine is a critical component inasmuch as it measures the
machine's operating pressure and hence its operation.
A defective or inoperative pressure gauge means the machine cannot operate at the required
pressure; make sure to keep a spare pressure gauge on hand in case of need.
The type of pressure gauge depends on the model of machine or optional configurations.
The standard pressure gauge is the analogue type with a Bourdon spring, with an aseptic design
diaphragm and a connection with specific design and dimensions for GEA Niro Soavi S.p.A. ; it
is also equipped with a separator with the function of filtering the normal pulsations of the piston
machine to allow a stable reading of the operating pressure.
Never separate the pressure gauge from its separator.
Other versions of pressure gauges or pressure meters are available as an alternative:
• analogue pressure gauge with signal transmitter: equipped with a 4-20 mA output for remote
transmission of the pressure signal
The pressure gauge does not normally require any maintenance, but it should be checked periodically
as follows:
• check the condition of the diaphragm in contact with the product; if any holes or damage to the
diaphragm are found, the pressure gauge must be replaced
• for analogue pressure gauges, check there is glycerine inside the dial; if necessary, fill up to 3/4
of the dial with 99.5% pure glycerine
• replace the gasket between the pressure gauge and head
