Sensonics has added a new option to
its range of proximity probes which,
it says, virtually eliminates the
detrimental effects on measurements
caused by both side and rear targets.

The new PRSVBeam offers a fully
protected rear and side view through
complete metallic encapsulation of
the probe sensor assembly and its
special tip design provides a beam
effect towards the target resulting in
good linearity, even if fitted with the
tip flush to the machine case or
mounting assembly. At the extreme
end of the probe range the effect is a
0.5% measurement error which
reduces to less than 0.2% in the
middle of the measurement range.

Another benefit claimed for this tip
design is its ability to withstand
pressures to 300bar and to provide
sensor tip protection when used in
heavy particle based fluids.
