Slide 3
Basis of hygienic instrumentation
The instrument should not effect the process.
The instrument should not effect the cleaning.
The process and the cleaning should not effect the instrument.
This basics where used by the EHEDG to develop their test.

Series 2 - sealing version
A, flange
We also have to differentiate between flange and screwed connection.
For both versions, two series each exist.
Series 1 is the screwed,
series 2 is defined as the flange version.
The sealing is equal for both.
Series 1 - sealing version

Varivent Inline housing
15/11/2005
Hygienic Process Connections
Michael Mies
Slide 23
The speciality of the inline housing
is that there is one process
connection size for several pipe
sizes. This means:
• Varivent Typ T/L is valid for pipe
diameters of DN 10 and DN 15
• Varivent Typ F is valid for pipe
diameters of DN 25 and DN32
• Varivent Typ N is valid for pipe
diameters from DN 40 up to
DN 162
This means e.g. that a Cerabar
pressure transmitter with Varivent
connection can be mounted in pipe
sizes of DN 40 - DN 162.
E+H sensors are not available for all sizes.
Varivent housing
We have to supply only 3 internal diameters:
31 mm, 50 mm and 68 mm.
