WARNING! Failure to observe this warning may result in serious injury.
The safety alert symbol on the nameplate means: Read these instructions for use, observe
the Specifications, and follow the Safety Instructions.
WARNING! Risk of injury from process medium
• Only correct installation (see dimension drawing) ensures a tight assembly.
• Do not dismantle the sensor as long as the process medium is under pressure!
All Applications
Hazards due to pressure, temperature, aggressive media or explosive atmosphere are pos-
sible, depending on the location of use. Therefore, the installation, operation, and servicing
of the sensor shall only be carried out by suitably trained personnel authorized by the oper-
ating company.
Hazardous Areas
Comply with all applicable local codes and standards for the installation of electrical equip-
ment in hazardous locations. For orientation, please refer to IEC 60079-14, EU directives
2014/34/EU and 1999/92/EC (ATEX), NFPA 70 (NEC), ANSI/ISA-RP12.06.01. The electrical and
thermal parameters of the sensors must be adhered to.
Memosens Ex sensors are marked by an orange-red ring. Combined with a model CA/
MS-***X** or model CA/MS-***X**-L measuring cable or a certified measuring cable which
is identical in hardware and function, the sensor may be connected to a suitable measuring
device, as described in the Certificates BVS 15 ATEX E141 X and IECEx BVS 15.0114X.

Special Conditions
• The cable and the sensor shall only be used within the ambient temperature range specified for
the temperature class.
• The measuring cable including its connecting head must be protected from electrostatic charg-
ing if it passes through areas of Zone 0 (category 1G).
• The Memosens sensors shall not be operated in electrostatically critical processing conditions.
Intense vapor or dust flows directly impacting on the connection system shall be avoided.
• Metallic process connection parts must be mounted at the installation site so that they are
electrostatically conductive (< 1 MΩ).
