Bently Nevada 330704-000-050-10-02-CN 3300 XL 11 mm Proximity Probe

Product Overview

The Bently Nevada 330704-000-050-10-02-CN is a non-contact eddy current sensor used as part of the 3300 XL 11 mm Proximity Transducer System. It measures the gap between the probe tip and a rotating shaft, providing high-accuracy displacement signals for radial vibration, axial thrust position, and phase reference (Keyphasor). It is commonly deployed in critical rotating machinery such as steam turbines, compressors, and other large industrial assets requiring continuous condition monitoring and protection.

Part Number Breakdown

  • 330704: 3300 XL 11 mm probe, 1/2-20 UNF thread, no armor

  • -000: Unthreaded length (0 mm)

  • -050: Case length (50 mm)

  • -10: Cable length (1.0 meter / 3.3 ft)

  • -02: Connector type with protector (ClickLoc coaxial with protective cover)

  • -CN: China regional certification/compliance

Engineering Advantages

  • Versatile 1/2-20 UNF Mounting
    The imperial thread form enables direct installation into legacy machine housings and bearing brackets commonly used in North American-standard equipment.

  • Extended Linear Range for Large Machinery
    The 11 mm probe design provides a 4.0 mm linear range, allowing it to accommodate large shaft movements due to thermal expansion and dynamic operating conditions without saturation.

  • Connector Protection for Harsh Environments
    The integrated connector protector (02 option) shields the ClickLoc interface from oil, moisture, and contaminants, helping maintain signal integrity and reduce false alarms.

  • Stable High-Frequency Signal Transmission
    The gold-plated ClickLoc connector ensures secure electrical contact and minimizes signal loss, even under high vibration and mechanical stress.

  • High Thermal and Chemical Resistance
    The PPS probe tip maintains dimensional stability and calibration accuracy under extreme temperatures and exposure to industrial lubricants and gases.

FAQs

Is this probe brand new and original?
Yes, it is supplied as 100% brand new, original Bently Nevada hardware with factory-sealed packaging and full traceability.

Can this probe be used with an 8 mm Proximitor?
No. It must be used with a compatible 3300 XL 11 mm Proximitor. Mixing probe sizes leads to incorrect calibration and unreliable measurements.

What does the “-CN” suffix indicate?
It signifies compliance with Chinese regional certification and industrial standards, making it suitable for projects implemented within China.

How do I select the correct extension cable?
The total system length must match the Proximitor calibration (commonly 5 m or 9 m). For this 1.0 m probe cable, you should pair it with a 4.0 m or 8.0 m extension cable accordingly.
