Bently Nevada 330101-00-36-10-01-00 Proximity Probes

Technical Specification Overview

The Bently Nevada 330101-00-36-10-01-00 functions as a high-precision, non-contacting sensor designed for the 3300 XL 8mm Proximity Transducer System. This probe measures both static (displacement) and dynamic (vibration) distances by generating an eddy current field that interacts with a target metal surface. By converting these physical changes into a proportional voltage signal, the probe allows the monitoring system to track shaft behavior with sub-milimeter resolution.

Design and Functional Capabilities

Engineers designed this specific probe configuration for applications requiring a standard 3/8-24 UNF threaded body and a 1.0-meter integral cable. The 8mm tip provides a standard linear range of 2.0 mm (80 mils), which remains the global benchmark for monitoring fluid-film bearings. Furthermore, the 3300 XL series offers enhanced thermal stability and a more consistent Scale Factor compared to legacy models, ensuring that data remains accurate even during significant temperature swings within the machine housing.

Operational Impact and Applications

This proximity probe actively powers predictive maintenance strategies by delivering high-fidelity data to Turbine Supervisory Instrumentation (TSI). Consequently, operators can identify mechanical issues—such as shaft misalignment, rotor imbalance, or bearing degradation—long before they escalate into catastrophic failures. Moreover, the integration of these probes into a 3500 Monitoring System allows for automatic machinery protection, including emergency trip functions.

Primary industrial applications include:

• Radial Vibration: Monitoring the orbit and dynamic movement of shafts in centrifugal compressors.
• Axial Position: Tracking the thrust displacement of rotors in steam and gas turbines.
• Keyphasor Signals: Providing a phase reference pulse to synchronize vibration data with rotational speed.

Mechanical Integrity and Resilience

To ensure survival in punishing environments, Bently Nevada utilizes a 304 stainless steel case and a PPS (polyphenylene sulfide) resin tip. This construction creates a hermetic seal that resists the ingress of oil, moisture, and steam. Additionally, the patented ClickLoc connector technology provides a secure, vibration-resistant electrical path. The included silicone boot further seals the connection, ensuring that environmental contaminants do not interfere with the sensitive electrical signals.
