VEGAFLEX 83 • 4 … 20 mA/HART two-wire

41839-EN-130612

In case of difficult installation conditions, for example in a socket, the

probe can be adapted respectively with a rod extension.
Let the probe length determine automatically by the instrument to

compensate the resulting running time changes.
You can find further information in the supplementary instructions of

the rod extension.

For use in an autoclave, e.g. for sterilization, the VEGAFLEX 83 is

available as autoclaved version.
Hence you can separate the housing from the process fitting.
Open the slotted nut with a hook wrench and remove the housing in

an upward direction.
The side of the process fitting must be covered with a lid after the

housing is removed. Screw the enclosed lid with slotted nut onto the

instrument side of the process fitting and tighten the nut with a torque

of 20 Nm.
Make sure that no liquid or contamination penetrates into the housing

or the process side.
After autoclaving, screw the lid off again and place the housing verti-

cally on the side of the process fitting. Tighten the slotted nut with a

torque of 20 Nm.
