The 330173-00-02-20-02-05 When combined with a 3300 XL Proximitor Sensor and XL extension cable, the system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface. The system can measure both static (position) and dynamic (vibration) data. Its primary use is in vibration and position measurement applications on fluid-film bearing machines, as well as Keyphasor measurement and speed measurement applications.
High precision for accurate monitoring
Reverse mount for narrow installation spaces
Durable & anti-interference for harsh environments
The system provides an accurate, stable signal output over a wide temperature range. All 3300 XL Proximity Transducer Systems achieve this level of performance with complete interchangeability of probe, extension cable, and Proximitor sensor, eliminating the need for individual component matching or bench calibration.

Aerospace & Defense
An engine test bench is used to monitor the rotor dynamics of crop engines during their development phase.
Marine & Shipbuilding
The Bently Nevada 330173 (3300 5mm) eddy current probe is mainly used to ensure the safety of core rotating equipment in ship propulsion systems and offshore operation platforms.
Mining & Cement
The Bently Nevada 330173 (5mm) eddy current probe plays the role of an "electronic stethoscope" in these industries, primarily responsible for monitoring those "throat devices" that, if damaged, would lead to a complete production halt.
Power Generation
Monitor the radial vibration and axial displacement of the turbine shaft to prevent catastrophic accidents caused by friction between moving and stationary parts.
Oil & Gas
Monitoring of critical equipment in long-distance natural gas pipelines and oil refineries.
Because the probe measures gaps at the micrometer level, any scratches, rust, or residual magnetic field on the surface of the measured shaft can be misread as "vibration." Therefore, it is essential to ensure that the shaft surface is flat, smooth, and demagnetized. During wiring, the signal cable should be kept away from high-voltage power lines and frequency converters, and maintained with single-point grounding to eliminate false alarms caused by electromagnetic interference.
What type of sensor is 330173-00-02-20-02-05, and what does it primarily measure?
Belonging to the Bentley 3300 XL series 5mm eddy current probe, it is mainly used to measure the radial vibration, axial displacement, key phase, and rotational speed of rotating machinery.
330173-00-02-20-02-05 的探头直径和量程是多少？
The probe has a diameter of 5mm and a standard linear measurement range of approximately 0–1.27mm (0–50mil).
Why must the 330173-00-02-20-02-05 be installed perpendicular to the surface of the shaft being measured?
Tilting can cause changes in the effective measurement area, resulting in excessive vibration, signal distortion, and inaccurate gaps, which can affect the reliability of protection logic.
How should the shielding layer of 330173-00-02-20-02-05 be grounded?
Use single-point grounding at the preamplifier end, and prohibit grounding at both ends to avoid forming ground loops and introducing interference.
What is the recommended installation gap for 330173-00-02-20-02-05?
Recommended installation gap: 0.50–0.65 mm.
