External access to a radially mounted probe is provided by Bently Nevada 31000-28-05-00-020-03-00 / 31000-28-05-00-066-03-02. The conductive PPS housing keeps the probe connector and retaining hardware outside the machine case while the sleeve carries the sensing tip toward the target.

Both 31000 records include a multiple-approval 3300 XL 8 mm probe with a 0.5 m cable and fitting set 03. The first uses a 2.0 in penetration without the outer mounting sleeve; the second uses a 6.6 in penetration and the 3/4-14 NPT outer-sleeve selection.

The full code controls whether the enclosure is only a probe-access housing or a complete threaded machine-case assembly. For 31000-28-05-00-020-03-00 / 31000-28-05-00-066-03-02, retaining hardware, cable grip and sleeve support must therefore follow the selected outer-sleeve option.
