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.

Varivent Inline housing

15/11/2005


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.
