330102-00-17-50-11-CN Bently Nevada Armored 3300 XL 8 mm Probe

Where This Probe Is Typically Used

330102-00-17-50-11-CN  is a field-proven 3300 XL 8 mm proximity probe designed for continuous shaft motion measurement in high-value rotating assets. Engineers commonly install this probe on steam turbines, centrifugal compressors, and large industrial pumps where vibration data directly drives protection logic.

In most plants, this probe operates as the front-end sensing element of a vibration protection channel. It converts shaft displacement into a stable electrical signal that the monitoring rack uses to trigger alarms or shutdowns. When installed correctly, the probe helps maintenance teams detect imbalance, misalignment, or bearing wear long before mechanical failure occurs.

The armored cable design is particularly valuable in environments where oil contamination, mechanical vibration, and cable abrasion are unavoidable.

Mechanical Identity of Model 330102

This base model is not a generic sensor. It is a specific mechanical configuration defined by Bently Nevada engineering standards.

330102 represents:

• 3300 XL series probe platform

• 8 mm sensing diameter

• 3/8-24 UNF mounting thread

• Integrated armored cable construction

• Industrial turbine-class vibration measurement

This definition remains consistent across all suffix variations. The suffix only changes physical length and connection details.

Configuration Details for 330102-00-17-50-11-CN

Each segment of the model number defines installation geometry. Maintenance teams rely on this structure when ordering replacements during outages.

Matching these dimensions exactly is critical for maintaining calibration and mechanical fit.

Core Hardware Characteristics

What Engineers Usually Verify Before Replacement

Is this a complete transducer system?
No. This model is the probe only. A working measurement channel requires a matched extension cable and Proximitor module.

Can this probe replace other 3300 XL probes?
Yes, if the mechanical length and cable configuration are identical. The monitoring system does not need modification.

What is the most common installation mistake?
Ordering the wrong cable length. A mismatch will not affect electronics but will prevent physical installation.

Does armored cable change measurement accuracy?
No. It improves mechanical durability and service life, especially in high-vibration turbine environments.

Field Installation Notes from Turbine Sites

Always confirm probe insertion depth before tightening the mounting nut. Excessive compression can shift the sensing position and introduce measurement drift.

Keep the probe cable separated from motor power lines and variable frequency drive wiring. Electrical noise is one of the most common causes of unstable vibration signals.

If the machine operates above 120 deg C ambient temperature, verify that the cable routing path avoids direct radiant heat from turbine casings.
