What is the 330104-00-15-50-12-00 sensor component?

This is a 3300 XL 8 mm proximity probe manufactured by Bently Nevada. It is a non-contact industrial measurement component specifically designed to monitor micron-level axial and radial movements of rotating machinery.

How do you properly install and use the 330104-00-15-50-12-00 probe on-site?

Screw it into the machinery's bearing housing bracket via the M10x1 thread on its case so that the probe tip directly faces the target shaft surface. Since it features an integrated 5.0-meter cable, its male coaxial connector must be plugged directly into a 5-meter system 3300 XL Proximitor sensor without an intermediate extension cable.

What is the core application of the 330104-00-15-50-12-00 probe in machinery condition monitoring?

It is primarily used for three major monitoring tasks on high-speed rotating machinery, dynamic radial shaft vibration, axial shaft displacement, and as a Keyphasor sensor for speed and phase angle measurement.

What is the operating principle of the 330104-00-15-50-12-00 sensor?

It operates based on the eddy current effect. A high-frequency signal from the Proximitor generates an alternating electromagnetic field at the probe tip via the cable. When a conductive metal shaft surface approaches this field, eddy currents are induced, causing system impedance changes that the Proximitor converts into a voltage signal proportional to the gap distance.

Do I need to purchase an additional extension cable when installing the 330104-00-15-50-12-00?

No. Because this specific part number features the -50 suffix, indicating it already comes with a 5.0-meter integral cable from the factory. It must be connected directly to a 5-meter Proximitor; adding an extension cable will alter the total electrical length and completely invalidate the calibration.

Information

Overview Manuals Common Applications Product Precautions

The 330104-00-15-50-12-00 is an industrial-grade eddy current displacement sensor probe, part of the industry-standard 3300 XL 8 mm measurement system. It is specifically designed for non-contact monitoring of shaft vibration, shaft displacement, and rotational speed in large rotating machinery.

One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor

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, 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

Utilizing its high temperature resistance (up to 177°C) to monitor the radial shaft vibration of high-pressure cylinder bearings in main steam turbines.

Petroleum Refining

Utilizing the patented FluidLoc leak-proof cable to prevent high-pressure, flammable oil and gas from leaking along the cable interior to the outside of the bearing housing, while monitoring rotor vibration.

Nuclear Power

Utilizing the integrated 5-meter stainless steel armor to route signals directly over a long distance to the Proximitor enclosure around narrow containment areas where intermediate junction boxes cannot be installed.

Hydroelectric Power

Measuring the oil-film thickness and shaft centerline orbit of hydro turbine main bearings under heavy-load operations.

Pulp & Paper Industry

Precisely detecting the micron-level dynamic gap between the rotating disc and stationary disc of high-speed refiners in environments dense with high-temperature steam.

When using the 330104-00-15-50-12-00, the following critical points must be observed. Because this model comes with an integrated 5.0-meter cable, it must be connected directly to a 5-meter system Proximitor sensor. Cutting, splicing, or forcibly adding an extension cable on-site is strictly prohibited as it will permanently invalidate the system calibration. During routing, the minimum bend radius of 25.4 mm must be respected to avoid excessive bending, and the integrated stainless steel armor alongside the ClickLoc self-locking connector should be fully utilized for anti-stepping and dust protection. Additionally, as the probe is factory-calibrated for AISI 4140 steel, the monitoring system scale factor must be adjusted if the target shaft is made of stainless steel or other alloys. When adjusting the installation depth, ensure the initial circuit gap voltage is set near the linear midpoint of approximately -10 VDC.

Technical notes

The Bently Nevada 330104-00-15-50-12-00 is configured with an M10×1 thread, a 0 mm unthreaded length, a 150 mm case length, and a 5.0 m cable. Equipped with a FluidLoc cable and a ClickLoc connector, this device precisely measures vibration and position on fluid-film bearing machines, while enabling complete interchangeability with non-XL 3300 series components. Because this specific model features an integrated 5.0-meter total cable, it connects directly to a 5-meter system 3300 XL Proximitor sensor without requiring a separate intermediate extension cable. Additionally, all components in this system provide excellent backward compatibility and are interchangeable with non-XL 3300 series 5 mm and 8 mm transducer system components.
