Rugged Armored Proximity Probe for Reliable Rotating Equipment Monitoring

The Bently Nevada 330102-05-20-10-02-05 3300 XL 8 mm Proximity Probe is an armored non-contact eddy-current sensor engineered for continuous monitoring of shaft vibration, shaft position, and radial displacement in critical rotating machinery. As part of the industry-proven 3300 XL 8 mm Proximity Transducer System, this probe delivers outstanding measurement accuracy, excellent environmental resistance, and dependable long-term performance for machinery protection and predictive maintenance applications. The armored cable construction provides additional protection against abrasion, vibration, and mechanical damage, making it ideal for demanding industrial environments.

This configuration features a 0.5 in. (12.7 mm) unthreaded length, a 2.0 in. (50.8 mm) overall case length, a 1.0 m (3.3 ft) integrated armored cable, a Miniature ClickLoc™ coaxial connector, and CSA, ATEX, and IECEx hazardous-area approvals. It is fully compatible with matching 3300 XL Proximitor Sensors and extension cables to create a complete proximity transducer system.

Technical FAQs

1. What is the primary purpose of this proximity probe?

It measures shaft vibration, shaft position, and shaft displacement using non-contact eddy-current technology for continuous machinery monitoring.

2. What distinguishes the 330102 series from the 330101 series?

The 330102 series incorporates an armored cable, providing greater mechanical protection than the standard non-armored 330101 series.

3. What does the "05" unthreaded length option represent?

It specifies a 0.5-inch (12.7 mm) unthreaded probe length.

4. What does the "20" case length option indicate?

It represents a 2.0-inch (50.8 mm) overall case length.

5. What cable length is supplied with this probe?

The probe includes a factory-installed 1.0-meter (3.3-foot) armored cable.

6. What connector configuration does this model use?

It uses a Miniature ClickLoc™ coaxial connector with a standard cable configuration.

7. What does Option 05 indicate?

Option 05 signifies CSA, ATEX, and IECEx hazardous-area approvals, allowing installation in certified hazardous locations.

8. Can the probe be used by itself?

No. It must operate with a compatible 3300 XL Proximitor Sensor and matching extension cable to complete the transducer system.

9. Why is an armored cable beneficial?

The armored cable protects against abrasion, vibration, crushing, and accidental mechanical damage, extending service life in demanding industrial environments.

10. Is this probe suitable for permanent online monitoring?

Yes. It is specifically engineered for continuous machinery protection and condition monitoring systems operating around the clock.
