Package Outline
Note: The pressure medium has contact to the following materials : Din 1.4305 Stainless
Steel, Viton
Nitrile rubber, Solvay
, Gold-plated Kovar
, Gold/Tin Solder, Silicon.
The user must ensure compatibility to these materials.
The rear-side of the silicon diaphragm carries the positive supply voltage. As the
pressure medium acts directly onto the silicon diaphragm, media which are ionic
or otherwise conductive cannot be applied to the sensor as this will lead to its
malfunction and/or destruction.
