Extension neck
Manufactured in stainless steel, the extension neck (part between the process connection and the housing) is
made up of a tube with a standard diameter of 15 mm and is 82 mm in length.
The upper connection of the neck permits adjustments to the orientation of the sensor head.
Process connection
This can be chosen form the following types:
Standard
connections are available in several sizes. Others (i.e. Neumo, APV) are available on request.
The process connection is continuously welded on the probe or on the well so as to obtain a minimum welding
radius of 3.2 mm between the lower surface of the connection and the sensor stem (according to EHEDG and
3-A
®
standards).
Please refer to paragraph on "Accessories" for information regarding availability of welding adaptors.
The Varivent
®
connections must be used with dedicated Tuchenhagen
®
in-line components or tank adaptors.
For Varivent
®
flanges with small nominal diameter, maximum immersion lengths for usual applications are
listed in the following table (also refer to figure 3).
Please be aware that in the past the Varivent
®
connection DN25 has been used also for pipes with nominal
diameter DN32.
