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.
