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 HOST with the following
maximum values: Uo= 14.4 V, Io = 116.5 mA, Po = 342.4 mW.
4.
The sensor does not provide isolation from earth. Installers shall take necessary
measures to prevent the possibility of sparking resulting from differing earth
potentials between the sensors and interconnecting equipment. This can be realized
for example by selecting interconnecting equipment which provides input-to-output
and input-to-earth isolation up to 500 V rms.

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.
