The 330180-50-05 is a Proximitor Sensor (pre-amplifier) manufactured by Bently Nevada for the 3300 XL 5mm/8mm proximity transducer system. As the core signal conditioning unit of the entire measurement loop, it provides a high-frequency excitation signal to the field probe and converts the micron-level gap variations into a DC/AC voltage output directly proportional to the distance. This specific model is engineered for a 5-meter total system length and is widely utilized in asset protection and condition monitoring for heavy industrial rotating machinery.

One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability.
All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors (such as this 330180-50-05 model), eliminating the need to match or bench calibrate individual components.
Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable with other non-XL 3300 series 5 mm and 8 mm transducer system components. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

Petroleum Refining Industry
Used for axial displacement and radial vibration monitoring of heavy rich gas compressors and main air blowers in catalytic cracking units, preventing mechanical collisions of impellers during high-speed operation.
Thermal Power Generation Industry
Installed on main bearings, feedwater pumps, and large induced draft fans of large steam turbine generator sets to measure dynamic shaft runout and thrust bearing wear in real time.
Nuclear Power Generation Industry
Implements continuous displacement monitoring for reactor coolant pumps and steam turbine rotors in the conventional island of nuclear power plants, ensuring compliance with extreme safety margins.
Hydroelectric Power Generation Industry
Used for radial swing (runout) measurement of vertical or horizontal shafts in hydro-turbine generator units, capturing mechanical wobbles caused by hydraulic unbalance or electromagnetic impacts.
Metallurgy & Iron and Steel Industry
Monitors the dynamic bearing runout of massive blast furnace blowers and Blast Furnace Gas Top Gas Recovery Turbines (TRT), coping with extreme high-load operating conditions.
Coal & Mineral Processing Industry
Employed for vibration protection of heavy main ventilation fans and massive ball mill gear drive systems in mining facilities, preventing unexpected shutdowns that cause underground hazards.
When using the 330180-50-05 Proximitor, you must strictly maintain a 5-meter total system length without cutting cables, ensure proper housing grounding during installation to prevent ground loops, use safety barriers with insulated connectors in hazardous areas, keep all cable connections clean and dry, and never measure the output terminals directly with a multimeter's resistance mode to avoid burning internal circuits.

Technical notes
Technical notes
The Bently Nevada 330180-50-05 is a high-precision 3300 XL 8mm Proximitor Sensor designed for large rotating machinery, which is compatible with 5-meter systems and compliant with the API 670 standard. Featuring international intrinsic safety certifications, it reliably converts mechanical displacement into a 200 mV/mil voltage signal for axial thrust and radial vibration monitoring. For detailed wiring definitions and hazardous area certificate requirements, please consult the product technical documentation.
It is a Proximitor Sensor (pre-amplifier) for the Bently Nevada 3300 XL transducer system, responsible for converting the probe's gap variations into standard voltage signals.
How to use products like 330180-50-05?
Mount it on a cabinet DIN rail, connect the high-frequency coaxial end to the extension cable and probe, and wire the terminal block to a -24Vdc power supply while outputting voltage signals to a safety monitoring system (such as the 3500 system).
What physical quantities can 330180-50-05 measure in rotating machinery?
It can precisely measure static values (such as thrust bearing axial position and rotor expansion) as well as dynamic values (such as shaft radial vibration runout, Keyphasor reference, and RPM speed).
What kind of signal interchangeability does 330180-50-05 have?
It supports complete interchangeability. Replacing this Proximitor eliminates the need to reassemble the entire measurement loop for individual matching or bench calibration.
What is the output impedance and output signal format of 330180-50-05?
Its output impedance is a standard 50 Ω; its output signal is a negative voltage directly proportional to the gap distance, with a standard scale factor of 7.87 V/mm (200 mV/mil).
