The 330101-00-25-05-01-05 Proximity Transducer Probe delivers precise, non-contact measurement of both static and dynamic shaft positions. Its high sensitivity ensures accurate vibration monitoring for critical rotating machinery in industrial applications. Built with a compact 8 mm diameter and a rugged housing, this probe incorporates TipLoc and CableLoc technology to secure the probe tip and cable. This design improves mechanical stability and reduces maintenance requirements in demanding operating conditions.
Ultra-stable scale factor for micron-level vibration & position sensing
Dual AC (dynamic vibration) & DC (static displacement) 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. 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.

When using 330101-00-25-05-01-05, never over-bend or pull its unarmored cable to prevent internal breakage. Strictly match the 5-meter or 9-meter total system length (probe and extension cable) to guarantee accuracy. Utilize a torque wrench for installation (11.2 N·m recommended) and avoid forcing the ClickLoc connector. Clean any oil contamination from the connector periodically.
330101-00-25-05-01-05 is a Bently Nevada 3300 XL series 8 mm proximity transducer probe used within this system to provide an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface. Featuring a fully threaded 3/8-24 UNF body (2.5 in overall case length, 0.0 in unthreaded length), the probe comes equipped with a 0.5-meter standard cable without armor and is terminated with a miniature coaxial ClickLoc connector. It is engineered to withstand an extreme operating temperature range of -51°C to +177°C and carries multiple international hazardous area agency approvals (including CSA, ATEX, and IECEx). Within its 2.0 mm (80 mils) linear measurement range, the system delivers high-precision static (position) and dynamic (vibration) measurements with a standard scale factor of 7.87 V/mm (200 mV/mil). The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
It is an industrial non-contact eddy current proximity probe belonging to the Bently Nevada 3300 XL 8 mm probe series.
What is the core function of 330101-00-25-05-01-05?
It measures static values (axial thrust position) and dynamic values (radial relative vibration, speed, and Keyphasor references) by fixing directly to the bearing housing.
How to install and use products like 330101-00-25-05-01-05?
Thread the probe into a standard mounting hole on the machine bearing housing, adjust the physical gap between the tip and the shaft surface, and secure it with a locknut.
What is the working principle of 330101-00-25-05-01-05?
Based on the eddy current effect, the matched proximitor generates an alternating magnetic field at the probe tip coil; when a metal shaft approaches, it alters the field, converting the gap distance into a proportional voltage signal.
Can this probe output industrial signals directly to monitoring systems?
No, it must be paired with a 3300 XL extension cable and a Proximitor Sensor to convert the signal into standard DC and AC voltage outputs.
