Process reference electrode (optional)
A process reference electrode can be installed similarly to the measurement electrodes
through the sensor lining. It will be made of the same material as the measurement
electrodes.
Grounding rings (optional)
Grounding rings can be installed between the flange and the sensor face on both ends of
the sensor. Single ground rings can be installed on either end of the sensor. They have an
I.D. slightly larger than the sensor I.D. and an external tab to attach ground straps.
Grounding rings are available in 316L SST, Nickel Alloy 276 (UNS N10276), titanium, and
tantalum. See Product Data Sheet.
Lining protectors (optional)
Lining protectors can be installed between the flange and the sensor face on both ends of
the sensor. The leading edge of lining material is protected by the lining protector; lining
protectors cannot be removed once they are installed. Lining protectors are available in
316L SST, Nickel Alloy 276 (UNS N10276), and titanium. See Product Data Sheet.
