Features:
- 3/8-24 UNF thread with 2.8-inch unthreaded length and 4.3-inch overall case provides balanced reach for medium-depth mounting applications.
- 8 mm construction with thicker PPS tip encapsulation delivers superior impact resistance and structural rigidity compared to 5 mm probes.
- Backward compatibility with non-XL 3300 series 5 mm probes enables direct replacement when mounting hole diameter accepts the larger 8 mm body.
The 330101-28-43-10-12-05 hits the sweet spot for medium-depth mounting. Its 2.8-inch unthreaded section passes through standard casings, while the 4.3-inch case keeps the probe from protruding excessively. No standoffs, no adapters—just a clean fit for typical turbine and compressor walls.
The 8 mm platform isn't just bigger—it's stronger. Thicker PPS plastic around the coil means the 330101-28-43-10-12-05 shrugs off impacts that would crack a 5 mm tip. The larger body diameter resists bending in high-vibration environments, keeping measurements accurate where smaller probes lose calibration.
Replace your old 5 mm probe with the 330101-28-43-10-12-05 without changing mounting holes or cabling. The 3/8-24 UNF thread matches existing ports. One-for-one swap, better durability, same footprint. For facilities tired of fragile probes, this is a straightforward upgrade.
The 330101-28-43-10-12-05 Bently Nevada 3300 XL 8 mm Proximity Probes may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Deep Hole Sleeve Installation: Designed for applications requiring penetration through thick machine housings or bearing housing covers. The non-threaded portion smoothly passes through the mounting hole, avoiding thread friction against the hole wall and facilitating installation near deep shaft surfaces.
- Large Turbine Machinery: Widely used for radial vibration and axial displacement monitoring in medium and large steam turbines, centrifugal compressors, and large gearboxes.
- Oil Environment Monitoring: Equipped with FluidLoc® cable (12), particularly suitable for installation in bearing chambers filled with lubricating oil, preventing oil from seeping out of the machine along the cable core.
- OK Circuit Diagnosis: When used with the 3500 system or Proximitor preamplifier, the system continuously monitors the probe's DC bias voltage (gap voltage). If the cable breaks, short-circuits, or the probe is damaged, the system immediately triggers a "Not OK" signal to prevent false alarms.
- TipLoc™ Technology: The probe tip is encapsulated in a high-strength material to prevent debris from falling into the machine in the event of accidental impacts (such as severe rotor vibration touching the probe).
- CableLoc™ Technology: Provides tensile strength up to 330 N (75 lbf), protecting the cable from breakage during installation or maintenance.
- Non-threaded Section Fit: The 2.8-inch non-threaded section must be fully inserted into the mounting hole, secured to the bracket only by the threaded portion.
- Gap Calibration: During installation, rotate the probe and monitor the output using a voltmeter. Set the gap voltage to approximately -10.0 VDC (center of the linear range).
- Tightening Torque: Use appropriate torque to tighten the nut to prevent probe loosening due to machine vibration.
