Expert Q&A for Large Machine Monitoring

Specifications & Use

• Why does this probe recommend a minimum 152mm (6″) shaft diameter?
• This is to prevent “crosstalk.” On small shafts, the probe’s electromagnetic field can wrap around, causing inaccurate readings. The larger shaft provides a proper target.

• What is the difference between M14 and M16 thread probes?
• The M16 thread is larger and stronger. It is often used on heavier machinery or where specification calls for the larger thread size. Always match the thread to your mounting hole.

Application & Selection

• Is the 330709-000-120-10-02-00 suitable for a steam turbine generator?
• Yes, it is an excellent choice. The M16 thread offers robust mounting, and its design for large shafts matches typical turbine generator rotor diameters.

• Can this probe be used for axial thrust position measurement?
• Yes, but ensure the target surface (thrust collar) meets the minimum flat diameter requirement of 30.5mm for accurate axial readings.

Procurement & Support

• Do you offer the same probe with a longer cable, like 5 or 9 meters?
• Yes. The 330709 base model is available in 1m, 5m, and 9m lengths. Contact us with your required cable length for the correct part number and pricing.
