Product Description

Overview

The 330145-14 from Bently Nevada is an 8mm eddy-current proximity probe engineered for precise, non-contact measurement of shaft vibration and position. It is part of the 3300 XL Proximity Transducer System and is commonly employed in turbines, compressors, motors, and other rotating machinery to ensure safe and reliable operation under extreme industrial conditions.

Key Features

High-Precision Measurement

• Non-contact detection using eddy current technology.

• Linear measurement range: 2.0 mm (80 mils), starting at 0.25 mm (10 mils) from the probe tip.

• Standard sensitivity: 7.87 V/mm (200 mV/mil) when used with a full 3300 XL system.

Durable Construction

• Probe body: Stainless steel (AISI 303 or 304) for corrosion resistance.

• Probe tip: Polyphenylene sulfide (PPS) for mechanical strength.

• Cable insulation: Fluoroethylene propylene (FEP) for high-temperature stability.

Robust Environmental Performance

• Operating temperature range: -51°C to +177°C (-60°F to +350°F).

• Patented TipLoc™ and CableLoc™ designs provide mechanical integrity under high vibration or flow conditions.

• Gold-plated ClickLoc™ connectors prevent loosening and maintain consistent electrical contact.

System Compatibility

• Works with 3300 XL extension cables and Proximitor® sensors.

• No bench calibration required when replacing probes or cables, reducing maintenance downtime.

• Compliant with API 670 4th and 5th Edition standards for critical machinery protection.

Technical Specifications

Applications

Ideal for monitoring shaft vibration and position in high-speed rotating equipment:

• Gas and steam turbines

• Pumps in chemical or power plants

FAQ

Q: Can the 330145-14 probe be used with other proximity transducer systems?
A: It is specifically designed for the 3300 XL system. Compatibility with other systems is not recommended.

Q: What is the purpose of the -14 suffix?
A: It indicates a 1.4-meter total probe length, typically chosen when a shorter integral lead is required before connecting to an extension cable.

Q: How does it handle extreme environments?
A: The combination of PPS tip, stainless steel body, and FEP-insulated cable allows operation in temperatures from -51°C to +177°C and in harsh industrial conditions.
