Application-Specific FAQ
Q: Is the 330903-00-25-10-02-00 compatible with the Bently Nevada 3500 rack?
A: Yes. The 3300 XL Proximitor output is fully compatible with all 3500 Series monitor cards that accept –24 VDC proximity inputs.
Q: Can this transducer measure axial position as well as radial vibration?
A: The 330903 probe can be installed in either radial or axial orientation. Axial (thrust) position measurement requires appropriate monitor card configuration (e.g., 3500/60).
Q: What target material is required for accurate readings?
A: AISI 4140 steel is the standard calibration target. Other ferromagnetic alloys may require a correction factor; non-ferromagnetic materials (e.g., titanium, Inconel) require special calibration.
Q: What is the difference between the probe cable length options in the part number?
A: The “-25-” segment denotes a 25 ft probe cable; “-10-” denotes a 10 ft extension cable. Total system reach = 35 ft (10.67 m) from probe tip to proximitor input.
Q: Do you provide calibration certificates?
A: Calibration documentation is available for factory-new units. For surplus units, functional verification reports are provided. Contact us for specifics.
