Flush Mounting
Flush mounting in a conductive fixture requires a cut-out area around the sensor
head. The depth and width of the cutout are relative to sensor face diameter as
shown in the diagram below. The cutout should never be any smaller than the
dimensions arrived at by making these calculations. Smaller width and/or depth
can result in loading effects so severe that you may not be able to calibrate the
system. The cut-out area may serve as a collection point for refuse, metal filings,
cutting oils, coolants, etc. It may also disrupt the gaseous or liquid flow patterns
in the measurement area. You can effectively solve this problem by backfilling
the cut-out area with a nonconductive material, such as silicon rubber or epoxy.
