Basic safety instructions
Wetted parts unsuitable for the process media
Danger of injury or damage to device.
Hot, toxic and corrosive media could be released if the process medium is unsuitable for
the wetted parts.
• Ensure that the material of the device parts wetted by the process medium is suitable for
the medium. Refer to the information in "Technical data" (Page 191).
Incorrect material for the diaphragm in Zone 0
Danger of explosion in the hazardous area. In the case of operation with intrinsically safe
supply units of category "ib" or devices of the flameproof enclosure version "Ex d" and
simultaneous use in Zone 0, transmitter explosion protection depends on the tightness of
the diaphragm.
• Ensure that the material used for the diaphragm is suitable for the process medium.
Refer to the information in the section "Technical data (Page 191)".
Unsuitable connecting parts
Danger of injury or poisoning.
In case of improper mounting hot, toxic and corrosive process media could be released at
the connections.
• Ensure that connecting parts (such as flange gaskets and bolts) are suitable for
connection and process media.
Note
Material compatibility
Siemens can provide you with support concerning selection of sensor components wetted by
process media. However, you are responsible for the selection of components. Siemens
accepts no liability for fa
ults or failures resulting from incompatible materials.
