Primary Application

This probe is specifically engineered for large rotating equipment like heavy-duty gas turbines, large steam turbines, and major centrifugal compressors. The M16 thread provides a robust mechanical connection, while the specifications ensure accurate vibration measurement on large-diameter shafts.

Expert FAQs

Q: What is the main reason to choose an M16 thread over an M14 thread?

A> The M16 x 1.5 mm thread is larger and stronger. It is used on the biggest, most critical machinery where maximum mechanical security and resistance to vibration loosening are essential. Always follow your machine’s original design specifications.

Q: Why are the recommended target and shaft sizes so large for this probe?

A> The 11mm probe tip has a larger electromagnetic field. To ensure accurate, linear output and to minimize “crosstalk” from nearby probes, it requires a larger target area. Using it on small shafts can change the scale factor and cause measurement errors.

Q: Can I use this probe on a shaft that is smaller than 152mm (6 inches)?

A> It is not recommended for axial position measurement on small shafts. The output may be non-linear. For radial vibration on smaller shafts, consult the technical manual’s “Target Effect” curves, but performance is not guaranteed.

Q: What is the advantage of the FluidLoc cable in this configuration?

A> On large critical machinery, cable reliability is paramount. The FluidLoc cable offers enhanced protection against moisture and chemical ingress over the long term, which is crucial for maintenance intervals and overall system uptime.

Q: How quickly can you ship this model and what are the payment terms?

A> The 330709-000-050-10-12-05 is typically available for quick shipment. We accept major credit cards and bank transfers. For confirmed stock status and to arrange expedited air freight via DHL/FedEx, please contact our sales team directly.
