INSTALLATION
LOCATION CONSIDERATIONS
2 - 2
•
The sensing area must be completely immersed into the fluid (Fig.
).
Partial and varying immersion will cause measurement errors.
•
The sensor position within the process pipe or any container during cal-
ibration must not cause air entrapment around the sensing area.
•
The sensor cable should be housed in a flexible type of metal or shielded
conduit to minimize the effects of radio frequency interference (RFI)
and electromagnetic interference (EMI). Submersion sensors require
nonflexible piping or conduit.
•
The sensor position must not allow accumulation of excess sediment or
other foreign material around the sensing area.
•
The sensor position must insure that the internal temperature sensor is
facing into the fluid flow path.
NOTE:
The temperature sensor is located at the sensing area on
the same side as the embossed PEEK insignia (Fig.
).
•
Lubricate all O-rings with a silicone grease or equivalent before assem-
bling the sensor into the installation hardware.
