What is the 330104-00-03-50-02-00?

This is a 3300 XL 8 mm reverse-mount non-contact eddy current proximity displacement probe manufactured by Bently Nevada, primarily utilized for physical displacement and vibration safety monitoring of industrial rotating machinery.

Which specific mechanical components usually employ the 330104-00-03-50-02-00 in industrial fields?

This probe is primarily deployed on industrial assets equipped with fluid-film bearings to continuously monitor drive shaft radial vibration, axial (thrust) position, and rotational speed.

What unique structural feature does the 330104-00-03-50-02-00 have during physical installation?

It is classified as a reverse-mount probe, which typically requires utilization in conjunction with a reverse-mount sleeve or an external mounting bracket in the field to allow physical threading from outside the machine housing.

What is the basic electromagnetic operating mechanism of the 330104-00-03-50-02-00?

An internal tip coil generates a high-frequency electromagnetic field. Variations in the physical gap between the conductive metal shaft surface and the probe tip alter the coil impedance, which is then converted into a voltage output by a Proximitor.

What target material is the 330104-00-03-50-02-00 calibrated to by default from the factory?

The factory default characteristic curve calibration is tailored to the physical surface of AISI 4140 steel (or equivalent carbon steel).

Information

Overview Manuals Common Applications Product Precautions

The 330104-00-03-50-02-00 is a 3300 XL 8 mm series proximity probe manufactured by Bently Nevada. As a non-contact, high-precision sensor, it is engineered specifically for the online monitoring of radial vibration, axial thrust displacement, Keyphasor (speed), and differential expansion in large rotating machinery, including steam/gas turbines, compressors, fans, and hydro turbines.

Supports full interchangeability
Backward compatibility
Compliant with American Petroleum Institute (API) 670 standards

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 and Proximitor sensors, 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.

Thermal Power Generation

Threaded into the exterior bearing housings of industrial steam turbines via reverse-mount sleeves to trace continuous axial thrust position and radial shaft vibration near the journal bearings.

Petrochemical Refining

Deployed on multi-stage hydrocarbon centrifugal compressors to monitor dynamic shaft vibration and oil-film physical stability, preventing volatile gas leakage induced by shaft misalignment.

Nuclear Power

Positioned via external brackets on safety-critical steam-driven main feedwater pumps to observe axial shaft displacement inside the non-containment secondary loop.

Hydroelectric Power

Positioned around the upper and lower guide bearings of massive vertical hydro-turbines to monitor the orbital tracking and radial runout of the generator main shaft.

Iron & Steel Metallurgy

Integrated into high-power blast furnace blowers via reverse-mount hardware to record thrust shaft movement against massive structural counter-forces during continuous air supply operations.

When utilizing this reverse-mount probe, it must be fully threaded into a specialized external sleeve or mounting bracket, with the initial mechanical gap between the tip and the fluid-film bearing shaft strictly controlled. Given its integrated 5.0-meter coaxial cable with a holistically pre-matched physical impedance, the minimum physical bend radius must not be less than 25.4 mm during field routing, and this line must be physically connected directly to a 5-meter type 3300 XL Proximitor Sensor without any intermediate extension cables.

Furthermore, precise axial alignment of the threaded case must be maintained during installation. Once the ClickLoc coaxial connector is secured by finger-tightening, original protective sleeving should be applied to achieve a complete physical seal, isolating the physical signal path from the ingress of external moisture, oil contaminants, or condensing steam around the bearing housing.

Technical notes

The 330104-00-03-50-02-00 is a 3300 XL 8 mm reverse-mount non-contact proximity probe manufactured by Bently Nevada, incorporating an integrated 5.0-meter coaxial cable that connects directly to a 3300 XL 5米 Proximitor Sensor. Physically featuring a fully threaded 30 mm (1.2 inches) rigid case, this hardware assembly is typically deployed from the exterior of fluid-film bearing machines via reverse-mount sleeves or brackets. It serves as the terminal physical sensor node within the complete eddy current protection chain, tracing relative shaft movement for radial vibration and axial thrust position monitoring, as well as providing Keyphasor phase reference and rotational speed tracking across critical industrial rotating assets.
