Description

The Bently Nevada 330101-00-13-05-02-00 is an 8 mm proximity probe configured with 0.0 inches of unthreaded length, a 1.3-inch overall case length, a 0.5-meter (1.6 feet) total probe length, a standard miniature coaxial ClickLoc connector, and is designed for applications where hazardous area approvals are not required. As part of the high-performance 3300 XL 8 mm Proximity Transducer System, this non-armored probe is uniquely tailored for direct, flexible installation into bearing housings, gearboxes, and internal dry wells where mechanical armor is unnecessary.

Utilizing the eddy-current operating principle, this non-contact sensor delivers precise, high-resolution measurements of machinery shaft vibration and position. It couples with a 3300 XL Proximitor sensor and extension cable to output a continuous voltage signal directly proportional to the distance between the probe tip and the target shaft. Designed to endure the harsh, oily, and high-temperature environments of industrial rotating machinery, it is widely utilized on steam turbines, gas turbines, compressors, and pumps to provide critical diagnostic and machinery protection data.

Features

• High-Accuracy Position Sensing: Designed for non-contact radial vibration, axial thrust, and speed measurements on rotating shafts.
• PPS Plastic Probe Tip: Robust polyphenylene sulfide (PPS) tip material provides an exceptionally strong encapsulation of the internal coil, protecting it from oil, moisture, and chemical attack.
• Stainless Steel Case: Constructed with a high-grade AISI 303 or 304 stainless steel threaded body for long-term corrosion resistance.
• Highly Flexible Cable: Equipped with a standard 75 Ohm triaxial FEP-insulated cable featuring a tight 25.4 mm (1.0 inch) minimum bend radius for routing in confined spaces.
• Secure Coaxial ClickLoc Connector: Gold-plated miniature ClickLoc coaxial connector ensures minimal signal loss, stable electrical connection, and easy finger-tight coupling.

Applications

The Bently Nevada 330101 proximity probe is deployed in diverse heavy-industry environments to monitor and protect critical rotating assets, including:

• Steam and gas turbine shaft vibration and axial displacement monitoring.
• Centrifugal pump and compressor rotor shaft displacement tracking.
• Industrial gearbox shaft runout and speed measurement.
• Hydroelectric generator guide bearing gap monitoring.
• Fans, blowers, and large electric motor shaft alignment verification.

Installation Guidelines

To ensure precise measurements and maximize the lifespan of the Bently Nevada 330101-00-13-05-02-00 probe, refer to the following industrial installation guidelines:

• Thread Engagement Limit: The maximum allowable thread engagement length for this 3/8-24 threaded probe is 0.563 inches. Exceeding this limit can cause binding and thread damage.
• Installation Torque: The recommended case mounting torque is 7.5 N-m (66 in-lbf). Never exceed the maximum rating of 22.6 N-m (200 in-lbf).
• Connector Tightening: Ensure the miniature ClickLoc coaxial connectors are kept free of contaminants. Hand-tighten connections firmly (recommended torque of 0.565 N-m or 5 in-lbf). Do not use pliers or tooling on standard gold connectors.
• Shielding and Grounding: Maintain proper shielding along the probe cable run, isolating signal paths from high-power field wiring. Securely ground the transducer system at a single point, usually at the monitor rack.

Compliance and Certifications

This proximity probe is a standard non-approved version (option code 00) intended for general purpose industrial environments. It is fully compliant with applicable commercial electrical safety regulations and RoHS environmental directives.
