Oiltech Controls Limited’s Insight
The 330709-050-120-10-02-00 is the primary choice for large turbomachinery with high axial float. Oiltech Controls Limited recommends this 11mm system when 8mm probes lack sufficient linear range. This specific 3300 XL 11 mm model excels in deep-reach mounting due to its 120mm case. It is compatible with 3300 XL Proximitor sensors for high-speed vibration diagnostics.

Professional FAQ
Is the 1.0-meter cable length sufficient for direct Proximitor connection?
The 1.0-meter 330709-050-120-10-02-00 requires a 4m or 8m extension cable to form a calibrated 5m or 9m system.
How do I verify the electrical health of the probe tip?
Check the DC resistance; RPROBE should measure 5.9 ± 0.5 ohms between the center and outer conductors.
Does the PPS tip material handle chemical exposure?
The Polyphenylene sulfide (PPS) tip resists most industrial lubricants, though users should avoid mechanical impact.
Why is the unthreaded length (050) important for my application?
A 50mm unthreaded section prevents threads from seizing in thick brackets or oil seals during deep installation.
Can I use an M16x1.5 probe in a NPT-threaded port?
Selection Guidance: Never force threads. Always use the correct M16x1.5 metric port or a verified mechanical adapter.
