Bently Nevada 330103‑080‑00‑05

Comprehensive Product Overview & Technical Guide (Offline Version)

1. Product Overview

The 330103‑080‑00‑05 is an industrial eddy current proximity probe used for non‑contact measurement of vibration, displacement, and shaft position in rotating machinery.

It is part of a family of proximity probes with an 8 mm tip diameter, designed to deliver reliable and accurate measurements for machine condition monitoring and protection.

This model is configured with a specific mechanical and system length combination, optimized for standard installation environments requiring short system length and compact probe housing.

The probe forms part of a complete vibration monitoring system by working in conjunction with a sensing module (proximitor sensor) and appropriate cabling.

4. Technical Specifications

5. Product Description

The 330103‑080‑00‑05 is engineered for reliable, continuous, real‑time monitoring of rotating shaft movement.

It functions by generating an electromagnetic field around the probe tip. As a conductive surface (shaft) moves within this field, changes are detected and converted into a voltage signal proportional to displacement.

With an 8 mm sensing tip and 80 mm unthreaded length, this model provides good access to shaft surfaces while accommodating standard mounting depths. The 0.5 m system length allows installations where moderate cable routing is needed, such as in compact machinery cabinets.

This configuration makes it suitable for environments with oil, dust, vibration, and temperature changes, without requiring frequent maintenance.

6. Applications

The 330103‑080‑00‑05 probe is widely used in:

• Steam turbines

• Gas turbines

• Centrifugal compressors

• Industrial pumps

• Electric motors

• Gearboxes

Typical monitoring functions include:

• Radial shaft vibration measurement

• Axial displacement detection

• Rotor position tracking

• Speed reference (Keyphasor)
