Bently Nevada 330104-01-08-50-01-05 3300 XL 8 mm Proximity Probe

The Bently Nevada 330104-01-08-50-01-05 is a part of the globally respected 3300 XL 8 mm Proximity Transducer System, known for its precision, ruggedness, and long-term reliability in industrial vibration monitoring and machinery protection. This particular probe is designed with an 5-meter system length, suitable for applications where the sensor and driver need to be spaced moderately apart due to layout constraints, temperature zones, or hazardous classifications.

This model is equipped with a 50-series ClickLoc connector, offering improved cable retention and resistance to mechanical loosening due to high vibration. Engineered to deliver accurate non-contact displacement measurements of rotating shafts, this proximity probe is commonly used in turbines, compressors, and high-speed industrial equipment where shaft vibration and position monitoring is critical for operational safety and efficiency.

Product Specifications

Applications

The 330104-01-08-50-01-05 proximity probe is designed for monitoring both dynamic vibration and static shaft position in a wide variety of rotating and reciprocating machines. Its most common applications include:

• Steam and Gas Turbines – For detecting shaft eccentricity, vibration amplitudes, and rotor movement.

• Axial Compressors – Monitoring vibration in high-speed rotary machinery.

• Pumps and Fans – To monitor misalignment, cavitation, or shaft instability.

• Motors and Generators – Assessing shaft displacement and ensuring proper operation.

• Gearboxes and Speed Reducers – To detect abnormal shaft behavior or gear engagement anomalies.

• Petrochemical and Refining Equipment – Particularly useful in ATEX-classified environments with potential exposure to gas or vapor.

Thanks to its robust build and sealing, it is also suited for offshore platforms, chemical processing plants, and remote compressor stations where environmental challenges are common.

Key Product Advantages

Frequently Asked Questions (FAQ)

1. What type of driver or Proximitor should I use with this probe?

   Use the 3300 XL Proximitor Sensor (P/N 3300-15-XX) that corresponds to the 8 mm probe system for best accuracy and linearity.

2. Is this probe rated for hazardous environments?

   Yes, when installed as part of an ATEX- or IECEx-certified system, it is safe for use in explosive or flammable environments.

3. Can the probe be installed near hot surfaces?

   The probe is rated for up to 120°C. Ensure that mounting points do not exceed this range during operation.

4. Does this model require any software configuration?

   No, it’s a passive analog device. Calibration is mechanical, and it integrates seamlessly with vibration monitoring systems.

5. What kind of shaft materials does it work best with?

   It is factory calibrated for AISI 4140 steel, but can be recalibrated for other materials using correction factors.

6. Can it detect both vibration and shaft position?

   Yes, this proximity probe is designed to detect both dynamic (AC) vibration and static (DC) position.

7. What’s the function of the ClickLoc connector?

   It provides a secure, vibration-resistant connection that prevents accidental loosening.

8. Is the probe shielded against electrical noise?

   Yes, the cable and connector are fully shielded to prevent EMI/RFI interference.

9. Can I extend the cable length beyond 5 meters?

   No, system length must match the specified 5 meters (probe + extension cable) for calibration accuracy.

10. How do I clean or maintain the probe?

    Clean using a soft lint-free cloth and mild solvent. Avoid abrasive cleaning materials or strong chemicals.
