The 330881-28-00-214-00-02 is a Bently Nevada PROXPAC XL Transducer Assembly, which integrates a standard 3300 XL 8 mm eddy current proximity probe and a Proximitor sensor into a single explosion-proof housing, enabling direct field wiring without an external extension cable. This specific configuration features multiple approvals (-28), a standard linear range of 2.0 mm, zero standoff length (-00), a 214 mm penetration depth (-214), no terminal fittings (-00), and a 3/4-14 NPT housing mount thread (-02).
Twice the width of a standard probe's linear range
High-fidelity signal with precise anti-interference capabilities
Multinational joint explosion-proof certification
The design of the PROXPAC XL Proximity Transducer Assembly is similar to our 31000/32000 Proximity Probe Housing Assemblies. The assembly offers the same advantages and features as the 31000 and 32000 housings for accessing and externally adjusting proximity probes. However, the housing cover of the PROXPAC XL Assembly also contains its own 3300 XL Proximitor sensor. This design makes the PROXPAC XL Assembly a completely self-contained proximity probe system, and eliminates the need for an extension cable between the probe and its associated Proximitor sensor. It also eliminates the need for a separate Proximitor housing, as the field wiring connects directly between the monitors and PROXPAC XL Assemblies.

Hydroelectric Power Generation
Leverages the 4.0 mm large linear range to measure wide-amplitude, low-frequency radial shaft runout and axial thrust displacement on large hydro-generator units.
Thermal Power Generation
Monitors thermal growth and axial differential expansion (DE) of high-capacity steam turbine generator sets during startup, shutdown, and peak loading.
Oil and Gas Exploration
Tracks high-amplitude vibration profiles on heavy-duty water injection packages and crude oil transfer pump bearing housings across offshore and onshore fields.
Petrochemical and Refining
Provides critical axial displacement machinery protection for million-ton scale ethylene cracked gas compressors and centrifugal main air blowers in hazardous explosive zones.
Coal Chemical Industry
Delivers non-contact condition monitoring for large-diameter shaftlines of Air Separation Unit (ASU) main compressors operating in heavy dust and flammable environments.
Steel and Metallurgy
Deploys the mechanical shielding of its stainless steel armor to resist iron scales and thermal impacts while plotting dynamic shaft centerlines of large low-speed blast furnace fans.
During the use of 330881-28-00-214-00-02, sufficient counterbore side clearance must be ensured around the 11 mm tip to prevent electromagnetic interference and signal distortion. The 21.4-inch cable must match the impedance of the specific 11 mm extension cable and Proximitor without any field cutting, maintaining a minimum bend radius of 25.4 mm. During installation, the static gap voltage must be calibrated to approximately -9 Vdc to prevent measurement clipping across its 4.0 mm linear range.
The 330881-28-00-214-00-02 features a no-fitting/standard configuration, making it suitable for direct cable outlets or standard sealed blind hole installations. It holds local and international explosion-proof certifications for ATEX/IECEx Zone 2 or Class I, Division 2 hazardous areas, meeting the safety compliance requirements of the petrochemical and energy industries.
It is a 3300 XL series 11 mm eddy current proximity displacement probe featuring a stainless steel braided armor sleeve from Bently Nevada.
What does the -28 option mean for 330881-28-00-214-00-02?
