Product Introduction
Bently Nevada 330180-91-05 is a 3300 XL Proximitor Sensor used in eddy-current proximity measurement systems. It receives the signal from a 3300 XL probe and extension cable, then outputs a voltage proportional to the distance between the probe tip and the observed conductive surface. This allows it to measure both static position and dynamic vibration.
The part number follows the 330180-AXX-BXX coding structure. In this format, “91” indicates a 9.0 m system length with DIN-rail mounting, and “05” indicates multi-agency approval. The 3300 XL Proximitor Sensor is commonly used with 3300 XL 8 mm probe systems for radial vibration, axial position, speed, and Keyphasor reference applications on fluid-film bearing machines, compressors, and turbines.
The 3300 XL family is designed for component interchangeability. Probes, extension cables, and Proximitor Sensors can typically be replaced without matching or bench recalibrating individual components, provided the system length and probe type remain consistent. It also supports backward compatibility with earlier non-XL 3300 series 5 mm and 8 mm components.
Some third-party listings describe 330180-91-05 as a display unit, relay module, or generic CPU card. That description is incorrect. 330180-91-05 is a Proximitor Sensor, not a 3500 display, relay, or controller module.

Note: The 9.0 m DIN-rail configuration and multi-agency approval are supported by the 330180-AXX-BXX ordering structure. Exact sensitivity, linear range, supply voltage, output scaling, and environmental ratings should be verified from the Bently Nevada 3300 XL Proximitor Sensor datasheet and the physical label.
Quality Control Process (DYNAMIC GENERATION)
- Label verification. We confirm the part number reads 330180-91-05 and matches the 3300 XL Proximitor Sensor family.
- System-length check. We verify the “91” configuration corresponds to a 9.0 m system and DIN-rail mounting.
- Physical inspection. The housing, terminal block, mounting clips, and connector interface are checked for damage or corrosion.
- Compatibility check. We confirm it is not mislabeled as a display, relay, CPU, or generic I/O module.
- Final packaging. After inspection, the unit is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Do not confuse it with a display or relay module. 330180-91-05 is a Proximitor Sensor; it is not a 3500 display, relay card, or controller.
❗ Match system length before replacement. The “91” suffix means a 9.0 m system. Replacing it with a 5.0 m or 1.0 m Proximitor may change system behavior if the probe and cable lengths are not adjusted.
❗ Confirm DIN-rail mounting. The “1” in “91” indicates DIN-rail mounting; do not substitute it with a panel-mount or no-hardware version without checking mechanical fit.
❗ Verify probe and cable compatibility. Ensure the existing probe and extension cable form a valid 9.0 m 3300 XL system.
❗ Check approval requirements. The “05” suffix indicates multi-agency approval; replacement units should meet the same approval needs if required by the installation.
❗ Maintain single-point grounding. Shielded cable grounding should follow Bently Nevada installation practices to avoid ground-loop interference.
❗ Handle as precision instrumentation. Avoid mechanical stress on terminals and connectors during installation.
Keep these in mind and you’ll cut 90% of rework time.
