Product Overview

The Bently Nevada 102550-01 is a high-precision eddy current sensor designed for the 3300 XL Proximity Transducer System. This 8mm probe performs non-contact displacement measurements to track shaft vibration and axial position in high-speed rotating machinery. The sensor converts the physical distance between the probe tip and the target into a proportional electrical signal. Engineered for extreme durability, the 102550-01 withstands aggressive industrial fluids and high-pressure environments, serving as the frontline defensive component for turbine and compressor protection.

Part Number Breakdown

The 102550-01 follows Bently Nevada’s metric hardware logic:

• 102550: Refers to the 3300 XL 8mm Proximity Probe with M10 x 1 metric threads.

• -01: Specifies the 1.0 Meter (3.3 feet) integrated cable length.

Technical Specifications

Engineering Advantages

• Harsh Media Resistance: The hermetically sealed TipLock construction prevents the ingress of lubricating oils, high-pressure steam, and corrosive contaminants. This ensures measurement stability even when the probe resides inside a machine's oil sump or casing.

• Precision Metric Integration: The M10 x 1 metric threading simplifies installation in European and Asian manufactured machinery. It allows for direct mounting into existing threaded ports without the need for specialized adapters or re-tapping.

• Advanced Shielding: The polyphenylene sulfide (PPS) probe tip and stainless steel body effectively minimize the "side-view" effect. This focuses the magnetic field directly ahead of the tip, allowing for accurate measurements in tight mechanical clearances without interference from surrounding housing.

• Mechanical Strength: The 303 stainless steel body resists mechanical deformation during installation and operation. The integrated cable features a robust strain relief that prevents damage caused by vibration-induced fatigue at the probe-to-cable transition.

• Gold-Plated Signal Integrity: The Click-Lock coaxial connector utilizes gold-plated contacts. This eliminates oxidation-related signal drift and ensures a low-impedance connection to the extension cable over decades of service.

FAQs

1. Does the 102550-01 probe require a specific Proximitor sensor?

Yes. You must pair the 102550-01 with a 3300 XL Proximitor (typically a 5-meter or 9-meter system depending on your extension cable length). Using it with older 3300 or 7200 series Proximitors will result in incorrect scale factors and measurement errors.

2. Is this probe 100% Brand New or surplus stock?

We supply the Bently Nevada 102550-01 as 100% Brand New original equipment. Each unit ships in original factory packaging with a traceable serial number and manufacturer's quality certificate.

3. Can I install this probe in high-pressure environments?

The 102550-01 features a hermetically sealed tip. It withstands pressures typically found in industrial gearboxes and bearing housings. If your application involves extreme vacuum or pressure, verify your casing seal requirements (e.g., using a probe housing with a pressure-rated seal).

4. What is the benefit of the 1.0m cable over the 0.5m version?

The 1.0m integrated cable offers more flexibility for routing the signal out of the machine casing to a junction box. It reduces the need for the extension cable connector to reside in extremely tight or oily spaces, facilitating easier maintenance and inspection.
