Remarks:
1.
No revision to this drawing without prior approval of FM.
2.
Installation must be in accordance with the National Electrical Code (ANSI/NFPA 70),
ANSI/ISA-RP12.06.01, and relevant local codes.
3.
The sensor shall be installed to a certified intrinsically safe Smart Adapter, model
SA11-C1, with the following maximum values: Uo= 6.6 V, Io = 100 mA, Po = 165 mW.
4.
The Installers shall take necessary measures to prevent the possibility of sparking
resulting from differing earth potentials between the sensors and interconnecting
equipment. The sensor itself does not provide 500 V rms isolation from earth, the
interconnecting equipment Model SA11-C1 Smart Adapter however provides this
required isolation.

INSTRUCTIONS
pH sensors containing accessible plastic parts and/or external conductive parts, must
be installed and used in such a way, that dangers of ignition due to hazardous
electrostatic charges cannot occur, especially in the case that the process medium is
non-conductive.
WARNING－POTENTIONAL IGNITION HAZARD – SEE INSTRUCTIONS
Contact Conductivity sensors containing light metals, must be installed and used in
such a way that, even in the event of rare incidents, ignition sources due to impact
and friction sparks are excluded.
