The 330102-00-40-05-01-00belongs to Bently Nevada's 3300 XL series 8mm eddy current probes. Unlike common forward-mounted probes, 330102 represents a reverse-mounted probe. This type of probe is typically used with a probe housing or mounted from the inside out of the machine, primarily for use in confined spaces or special monitoring locations where it is impossible to directly screw it into a threaded hole from the outside.
One 3300 XL 8 mm probe
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, eliminating the need to match or bench calibrate individual components.

Hydro Power
Used in conjunction with waterproof housings to monitor the radial vibration and axial movement of large-diameter shafts.
Thermal Power
Used for steam turbine thrust bearing monitoring. The reverse mount design allows for probe adjustment via specialized sleeves on heavy casings to measure axial displacement (thrust).
Oil Refining
Used on large centrifugal blowers. Installed within shaft end protective housings to monitor rotor operating status in real-time, preventing bearing damage.
Cement Production
On the main motor bearings of vertical mills. Utilizing its rugged CableLoc™ design, it monitors the radial position of the motor shaft on high-vibration production lines.
Pulp & Paper
On the support bearings of large paper machine dryer cylinders. It monitors bearing clearance changes in high-temperature environments, with the reverse mount housing protecting the probe from humid steam.
When using the 330102-00-40-05-01-00 reverse-mounted probe, it must be ensured that it is used only in non-explosion-proof areas (as it lacks institutional certification), and installation must be strictly performed in conjunction with the probe protective cover. During installation, a multimeter must be used to monitor and precisely lock the initial gap at the linear midpoint of approximately -10V. It is strictly forbidden to cut the cable without authorization to maintain system impedance matching. At the same time, the coaxial connector must be properly sealed to prevent water and oil damage, and the leads must be secured to ensure signal stability in outdoor or harsh working conditions.
The 330102-00-40-05-01-00 is a 3300 XL series 8 mm Eddy Current Proximity Probe manufactured by Bently Nevada.
How to use products like the 330102-00-40-05-01-00?
To use it, thread it into the machine's bearing housing or mounting bracket so that the probe tip directly faces the rotating shaft surface, and adjust the thread depth to ensure the initial installation gap is within the linear region. It cannot be used alone and must be connected to a 3300 XL Proximitor via a 3300 XL extension cable.
What is the primary function of the 330102-00-40-05-01-00 in the system?
Its primary function is serving as the "front-line sensor" for the monitoring system, converting minute dynamic or static displacements on the shaft surface into electrical signals without contact, enabling continuous monitoring of bearing vibration and axial shift.
What is the function of the stainless steel armor on the 330102-00-40-05-01-00?
The armor provides extremely strong physical protection. In harsh industrial environments, it prevents the cable from being damaged by external pulling, sharp object scraping, mechanical wear, or high-temperature splatter.
What should be paid attention to in the daily maintenance of the 330102-00-40-05-01-00?
The maintenance focus is on keeping the cable connector clean and never letting oil or dust contaminate its interior, which affects measurement accuracy; additionally, sharp bends in the cable must be avoided, keeping the bend radius above 25.4 mm.
