Overview Manuals Specifications Applications Protection Features Key Installation Points

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.
Description
The Bently Nevada 330101-28-43-10-12-05 is a precision-engineered 8mm non-armored eddy current proximity probe from the industry-proven 3300 XL Machinery Protection System, specifically designed for non-contact measurement of shaft vibration, axial displacement, key phasing, and rotational speed in critical rotating machinery. Featuring an 8mm sensing diameter, M10×1 threaded interface, 43mm housing length (designated by "43" in the model), and a 1.0m non-armored coaxial cable (indicated by "10") terminated with a robust BNC connector (designated by "12"), this probe delivers reliable high performance with a sensitivity of 100 mV/mil (3.94 V/mm), an output signal range of 0-10 V DC, and a rapid response time of less than 1 ms, operating on a power supply of -17.5 Vdc to -26 Vdc. 

Engineered to thrive in harsh industrial environments, it boasts a wide operating temperature range of -51°C to 177°C, an IP65 protection rating for the stainless steel housing, and braided copper shielding on the cable to minimize EMI/RFI interference, ensuring consistent signal integrity amid oil, dust, and vibration.
