The Bently Nevada 330104-00-10-10-01-05, also cataloged as the 330104 proximity probe, operates as an armored eddy-current sensor for shaft vibration, axial position, and speed measurements within 3300 XL 8 mm probe systems.
Suffix Breakdown & Model Matrix
330104 → Base model, 3300 XL 8 mm proximity probe, metric thread, stainless steel armor.
00 → Unthreaded length option, 0 mm.
10 → Case length option, 100 mm.
10 → Cable length option, 1.0 m (3.3 ft).
01 → Connector option, miniature coaxial ClickLoc connector with protector, standard cable.
The probe is calibrated for –10 VDC gap voltage validation, ensuring accurate displacement conversion when paired with a matching 3300 XL Proximitor Sensor. Its stainless steel armor provides mechanical protection in harsh environments, while the coaxial system maintains impedance matching and suppresses cross-talk. Interchangeability across the 3300 XL series eliminates the need for bench recalibration.
Frequently Asked Questions
Q: What is the linear operating range of the probe? A: The probe supports a 2 mm (80 mils) linear range.
Q: What certifications are included? A: CSA, ATEX, and IECEx hazardous area approvals are provided under suffix –05.
Q: Is calibration required when replacing probes? A: No, the probe is fully interchangeable with other 3300 XL components without bench calibration.
Field Installation Guidelines
Install probe tip perpendicular to shaft surface for accurate displacement measurement.
Maintain insertion depth to achieve –10 VDC gap reference.
Route armored coaxial cable with shielding grounded at a single point to minimize interference.
Avoid sharp bends in cable to prevent conductor fatigue.
Confirm driver calibration after installation to ensure proper scaling.
