The Bently Nevada 330801-28-04-105-00-02 is a PROXPAC XL Proximity Transducer, a self-contained unit combining a 3300 XL 8mm probe and sensor (no external proximitor). It features a 39mm probe penetration, 3/4-14 NPT fitting/reducer, and IP66 housing for harsh environments, commonly used for monitoring rotor position in industrial machinery.

The design of the PROXPAC XL Proximity Transducer Assemblyis similar to our 31000/32000 Proximity Probe HousingAssemblies. The assembly offers the same advantages andfeatures as the 31000 and 32000 housings for accessing andexternally adjusting proximity probes. However, the housingcover of the PROXPAC XL Assembly also contains its own 3300XL Proximitor sensor. This design makes the PROXPAC XLAssembly a completely self-contained proximity probesystem, and eliminates the need for an extension cablebetween the probe and its associated Proximitor sensor. Italso eliminates the need for a separate Proximitor housing, asthe field wiring connects directly between the monitors andPROXPAC XL Assemblies.

The 330801-28-04-105-00-02 Bently Nevada PROXPAC XL Proximity Transducer may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Order in increments of 1 mm. Note that theindividual probe sleeve length does notinclude the distance from the end of thesleeve to the probe tip or the gap from theprobe tip to the target material. If only thepart number of the original housing is knownand the sleeve cannot be measured, use thefollowing formula to determine the sleevelength: AStandoff Adapter Option from originalhousing (330801 option B) * 10 + Probepenetration option from original housing(330801 option C) + 063. Example:
Original part number is 330801-16-08-205-03-02.
A option for replacementsleeve is (080 + 205 + 063) = 3 4 8.
Minimum Probe Sleeve Length:88 mm (3.5 in) = 0 8 8
Maximum Probe Sleeve Length:823 mm (32.4 in) = 8 2 3

The Bently Nevada 330801 and 330880 are both PROXPAC XL proximity transducer assemblies designed to measure shaft vibration and position. They combine the standard 3300 XL 8 mm probe and Proximitor sensor into a single, self-contained housing, though the 330880 features an updated, more chemically resistant Polyphenylene Sulfide (PPS) design. 

FAQs

  • What is the 330801-28-04-105-00-02?

    +
    The Bently Nevada 330801-28-04-105-00-02 is a 3300 XL PROXPAC Proximity Transducer Assembly. It combines a probe, extension cable, and Proximitor sensor into a single, compact housing to measure static and dynamic distances between the probe tip and a target, making it ideal for monitoring machinery vibration and position.
  • What is the fundamental working principle?

    +
    It utilizes the eddy current effect. The system sends a radio frequency (RF) signal through a coil in the probe tip. When a conductive target (like a machine shaft) moves closer or further away, it alters the magnetic field, providing an output voltage directly proportional to the gap.
  • How does 330801-28-04-105-00-02 measure vibration?

    +
    When the distance between the probe and the target surface changes, the eddy current loss also changes, and the sensor converts this change into a proportional voltage signal.
  • Is this assembly waterproof?

    +
    While the sensor and probe are rated for 100% condensing humidity and are non-submersible, they must be properly sealed to prevent moisture from entering the housing.
