Ex-classification ATEX

2.6.1 Introduction
According to Directive 94/9/EC (ATEX 95) Appendix I,
the O oxygen sensors type InPro 6XXX is a devices
2
of equipment group II, category 1/2G which, accord-
ing to Directive 99/92/EC (ATEX 137) can be used in
zones 0/1 or 1/2 or 1 or 2 as well as gas groups IIA,
IIB and IIC, which are potentially explosive due to
combustible substances in the temperature T3 to T6.
The requirements specified in EN 60079-14 must be
observed during use / installation.
According to Directive 94/9/EC (ATEX 95) Appendix
I, the O oxygen sensors type InPro 6XXX is a de-
2
vices of equipment group II, category 1/2D which,
according to Directive 99/92/EC (ATEX 137) can be
used in zones 20/21 or 21/22 or 21 or 22, which
are potentially explosive due to combustible dust.
The requirements specified in EN 60079-14 must be
observed during use / installation.
For the analog version of the O
the O measurement circuit, temperature measure-
2
ment circuit and data chip circuit are part of the com-
mon intrinsically safe system and are jointly connect-
ed to and operated by a separately certified
transmitter.
The digital version of the O
nected to and operated by two-wire cable to the certi-
fied transmitter.
The intrinsically safe circuits are galvanically isolated
from the non-intrinsically safe circuits up to a nomi-
nal voltage peak value of 375 V and from the earthed
parts up to a nominal voltage peak value of 30 V.
