Mounting a centering disc for pipe installations
To prevent the probe from contacting the chamber or pipe wall, centering discs are
available for rigid single, flexible single, and flexible twin lead probes. The disc is attached to
the end of the probe. Discs are made of stainless steel, Alloy C-276, Duplex 2205, or PTFE.
The centering disc in PTFE is not available for HTHP probes.
For the segmented rigid single lead probe, up to five PTFE centering discs can be mounted
along the probe, but keep a minimum distance of two segments between the discs.
Additionally, a disc in SST or PTFE (part number 03300-1655-xxxx) can be attached to the
end of the probe.
See
for the appropriate disc diameters.
When mounting a centering disc, it is important that it fits correctly in the chamber/pipe.
See
for dimension D.
