Expert Review: Manager’s Insight

For plant reliability managers, the 330191-02-16-90-00 is the workhorse for tight installations. The 0.2-inch unthreaded length (02 option) is key for precise gap setting in confined spaces, while the 9-meter cable (90 option) offers flexibility to route to junction boxes without extra splicing. Its T1 temperature rating ensures dependable performance in high-heat turbine and compressor applications. We recommend this variant when you need the durability of an 8mm probe but have limited clearance for the sensor tip.

Frequently Asked Questions (FAQ)

What is the main function of this specific probe model?
It precisely measures shaft vibration and relative position in rotating machinery like steam turbines, centrifugal compressors, and gearboxes.
Can I use this probe without an extension cable?
No. Probes with a total length of 9.0 meters require a separate extension cable to connect to the Proximitor, except for 1-meter system designs.
How do I choose between this and the 5mm probe series?
The 8mm probe offers a thicker, more rugged case and tip encapsulation. Choose 5mm probes only if your mechanical installation has a smaller mounting hole requirement.
What does the ‘ETR’ in the model description mean?
ETR stands for Extended Temperature Range. This means the probe is rated for reliable operation in ambient temperatures up to +232°C.
Is the FluidLoc cable option necessary for my application?
If your machine uses oil lubrication and you are concerned about oil wicking through the cable interior into the case, select the optional FluidLoc design to prevent leakage.
