Oxymax W COS51D Safety instructions
Hauser 5
1.4 Sensor version for applications in hazardous locations
• The certified oxygen sensor Oxymax W COS51D-G**0 may only be connected via the measuring
cable CYK10-G**1 to approved intrinsically safe digital sensor circuits of the transmitter Liquiline
M CM42-*G*. The electrical connection instruction must be followed.
• The measuring cable CYK10-G and its coupling must be protected from electrostatic charging, if
installed through zone 0.
• The sensor may not be operated under process conditions where electrostatic charging is likely to
occur. The designated use in media with a conductivity of at least 10 nS/cm can be assumed as
electrostatic uncritical.
• Ex versions of digital sensors with Memosens technology are indicated by an orange-red ring on
the plug-in head.
• The maximum permissible cable length is 100 m (330 ft).
