Sensors used in Ex areas must be con-

nected only to intrinsically safe circuits. The

permissible electrical values are stated in the

conformity certificate or the type approval

certificate.

Intrinsically safe circuits with more than one

active instrument (instrument delivering elec-

trical energy) are not allowed. Please note the

special installation regulations (DIN VDE

0165).

Certain pressure transmitters are provided

with a warning label informing of measures to

be taken to avoid the danger of electrostatic

discharge. Note the content of the warning

label.
