WARNING
Electrical connection
Cable extension and sensor connection should be accomplished by author-
ised expert staff only.
WARNING
Possible electrical interference
If you wish to extend cables by using a terminal box use a box made of metal.
The shields of outgoing as well as incoming cables must be wired to the
ground connection of the terminal box.
Inappropriate connections leading to increased contact resistance or the use
of unsuitable cables may result in interferences or even measurement fail-
ures.
Sensors with integrated pressure cell and sensor connection type „L“ (see Fig.
2-12) are equipped with a specially prepared cable type LIY11Y 2x1.5 mm² +
1x2x0.34 mm² + PA 1,5/2,5. Sensors without pressure measurement cell as well
as the external Electronic Box with sensor connection type "K" are equipped with
cables type LIY11Y 2x1.5 mm² + 1x2x0.34 mm². These cables can be extended
without any problem by using single shielded signal cables.
Sensors with integrated pressure cell and sensor connection types "F" or "S"
are equipped with the respectively wired plugs; type „F“ are equipped with an
additional air filter with a dehydration agent on the connection plug (see Fig.
5-26). These sensors cannot be extended.
