2.6.1 Introduction

According to RL 94/9/EG (ATEX 95) Appendix l, lnPro
6XXX*/*/*/*/* oxygen sensors are devices group ll,
category 1/2G and according to RL 99/92/EG (ATEX
137) may be used in zones 0/1 or 0/2 and gas groups
llA, llB and llC that are potentially explosive due to
combustible substances in the temperature class T6.
For use / installation, the requirements of EN 60079-
14 must be observed.
According to RL 94/9/EG (ATEX 95) Appendix l, lnPro
6XXX*/*/*/*/* oxygen sensors are devices group ll,
category 1/2D and according to RL 99/92/EG (ATEX
137) may also be used in zones 20/21 that contain
combustible dusts.
The digital sensor circuit is part of a common intrinsi-
cally safe system and is for opera tion connected to a
separately certified transmitter.
The digital sensor circuit as part of an intrinsically
safe system is isolated from the not- intrinsically safe
electric circuits up to a maximum rated voltage of 375
V and from grounded parts up to a maximum rated
voltage of 30 V.
