Product Description
The Bently Nevada 330145-14 is a high-precision non-contacting proximity probe designed for critical machinery protection and condition monitoring. As part of the 3300 XL 8 mm series, it uses eddy current technology to measure both static position (gap) and dynamic motion (vibration) between the probe tip and a rotating shaft.
Engineered for long-term reliability in harsh industrial environments, the 330145-14 provides essential inputs for radial vibration, axial thrust position, and speed measurements on rotating equipment. This specific configuration features a 1.4-meter probe length, making it ideal for installations involving deep bearing housings or complex machine geometries. The PPS probe tip ensures excellent resistance to chemical attack, oil immersion, and thermal expansion.

Application Scenarios
The 330145-14 is widely used in power generation and petrochemical facilities for monitoring critical rotating machinery, including:
-
Centrifugal compressors
-
Steam and gas turbines
-
Large industrial pumps
It is particularly effective for early detection of rotor instability, misalignment, and bearing wear, helping prevent unplanned outages and catastrophic failures.
Frequently Asked Questions
Does the 330145-14 require a Proximitor Sensor?
Yes. The probe must be used with a Bently Nevada 3300 XL Proximitor Sensor and a compatible extension cable to form a fully calibrated measurement system.
Is the 1.4 m length inclusive of the extension cable?
No. The 330145-14 refers only to the probe assembly. The system’s total electrical length (typically 5 m or 9 m) is achieved by adding the appropriate extension cable.
