Bently Nevada 330103‑11‑16‑10‑12‑RU

Comprehensive Product Overview & Technical Guide (Offline Version)

1. Product Overview

The 330103‑11‑16‑10‑12‑RU is a high‑precision eddy current proximity probe designed for continuous, non‑contact measurement of rotating machinery motion.

It measures vibration, radial and axial displacement, and shaft position without mechanical contact, providing reliable data for machine condition monitoring and protection systems.

This model belongs to the 3300 XL proximity probe series with an 11 mm nominal probe tip diameter, which is larger than standard probes to provide improved signal strength and measurement clarity, particularly in machines with larger shafts or higher displacement requirements.

The model code 11‑16‑10‑12‑RU breaks down as:

• 11 mm probe tip diameter — for strong signal response.
• 160 mm case length — suited for medium‑depth mounting positions.
• 1.0 m system cable length — convenient for routing in control cabinets or plant conduits.
• Connector variant “12‑RU” — a regional connector option tailored for Russian industrial interface standards, offering mechanical and electrical stability in rugged environments.

This proximity probe is engineered for long‑term, stable operation in harsh industrial environments, delivering precision measurement for predictive maintenance and machinery protection.

4. Technical Specifications

5. Product Description

The 330103‑11‑16‑10‑12‑RU proximity probe uses eddy current sensing technology to detect changes in distance between the probe tip and a conductive shaft surface. When the shaft moves within the electromagnetic field generated by the probe tip, changes in induced current are converted into an analog voltage signal proportional to displacement.

The 11 mm tip diameter offers stronger signal output, particularly useful for larger shafts or conditions where signal quality is critical. The 160 mm case length supports medium‑depth mounting in machine housings or bearing pedestals. The 1.0 m coaxial cable provides flexibility in routing to monitoring or protection modules. The 12‑RU connector variant ensures reliable mechanical and electrical connection in regional industrial standards for rugged installations.

The probe’s IP67 sealing helps protect it from dust, oil spray, and moisture, while rugged internal construction ensures stable performance under vibration and thermal stress.

6. Applications

The 330103‑11‑16‑10‑12‑RU proximity probe is suited for a wide range of industrial rotating equipment, including:

• Steam turbines — monitoring radial and axial shaft motion to protect against rub, imbalance, and bow.
• Gas turbines — tracking vibration levels and shaft displacement.
• Centrifugal compressors — detecting imbalance or misalignment before failure.
• Industrial pumps — monitoring shaft motion and early fault detection.
• Electric motors — tracking rotor dynamics and vibration.
• Gear reduction systems — measuring shaft movement under load.

Measurement functions include:
• Radial shaft vibration monitoring.

• Axial or differential displacement measurement.

• Shaft centerline position monitoring.

• Speed reference (Keyphasor) outputs for phase and timing analysis.

These measurements help identify machinery faults early, enabling predictive maintenance and preventing unscheduled machine shutdowns.
