The 330102-00-83-50-02-05 is an 8mm proximity/eddy current displacement sensor probe from the 3300 XL series. This model is specifically designed for condition monitoring of industrial rotating machinery in confined spaces, harsh oil-rich environments, and high-risk explosion-proof areas.
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.

Oil Refining
Used on compressor hydrodynamic bearings in hydrocracking units; relies on -05 intrinsic safety to safely perform non-contact shaft vibration and displacement measurements in flammable environments.
Petrochemicals
Deployed on ethylene cracking gas compressors; the 5m integrated cable routes the connector to an explosion-proof box, eliminating intermediate joints within oil-mist hazardous areas.
Thermal Power
Used on large boiler feed pump hydrodynamic bearings; the reverse-mount design allows zero-voltage calibration via an external sleeve, without removing thick thermal insulation layers.
Coal Chemical
Used on heavy-duty high-pressure syngas compressors; the PPS probe tip resists erosion from corrosive gases and oil contamination residual from the gasification process.
Hydro Power
Installed on guide bearings of horizontal pumped-storage hydro units; utilizing the 2.0 mm standard linear range to accurately capture shaft orbit caused by hydraulic imbalance.
When using the 330102-00-83-50-02-05 probe, the core focus lies in "precise metric sleeve micro-adjustment, 5-meter intrinsically safe grounding, and noise isolation". First, since this model features an M10×1 metric reverse-mount design, you must ensure its external reverse sleeve is rigidly stable with at least 3mm of metal-free clearance around the tip, using a multimeter to precisely calibrate the initial gap to the center voltage (approx. -10 VDC). Meanwhile, as the probe comes with a 5-meter integrated cable without any intermediate joints, you must strictly maintain a bending radius greater than 25.4 mm during routing, absolutely forbid cutting or splicing the signal wire, and because it carries agency approvals (-05), it must be paired with safety barriers and specified Proximitors in hazardous areas with proper grounding for the armor or housing to thoroughly eliminate impedance mismatch, intrinsic safety failures, and electromagnetic interference (EMI).
It is a 3300 XL series 8mm reverse-mount metric proximity probe manufactured by Bently Nevada. It is a non-contact sensor used for the precision monitoring of industrial rotating machinery.
What is the primary operating principle of 330102-00-83-50-02-05?
It operates based on the eddy current principle. The probe tip coil generates a high-frequency electromagnetic field, which induces eddy currents when near a metallic shaft surface. The resulting impedance change is converted into an output voltage proportional to the gap.
How do you correctly use a reverse-mount product like 330102-00-83-50-02-05?
Users need to secure a dedicated reverse-mount sleeve or external housing to the machine first. Then, insert this probe from the inside of the sleeve outward, adjust the initial gap, tighten the probe, and connect its integrated 5-meter cable directly to the Proximitor.
What is the standard linear measurement range of 330102-00-83-50-02-05?
As a standard 8mm probe in the 3300 XL series, its standard linear measurement range is 2.0 mm. Its official fixed standard output sensitivity is 7.87 V/mm.
In which industrial sectors can the 330102-00-83-50-02-05 be used?
It is widely used in heavy industrial sectors with high hazards and strict explosion-proof requirements. These include oil exploration, petrochemical refining, natural gas pipelines, thermal power generation, and coal chemicals.
