Bently Nevada 330101-00-30-50-02-00 3300 XL 8 mm Proximity Probe

Description

Designed for non-contact machinery protection, the Bently Nevada 330101-00-30-50-02-00 is a high-performance 8 mm proximity probe engineered to measure static and dynamic shaft displacement on critical rotating machinery. As an integral component of the 3300 XL 8 mm Proximity Transducer System, this probe operates on the eddy-current principle to provide precise, continuous vibration and position measurements. This specific configuration features a fully threaded 3.0-inch stainless steel case without unthreaded length, making it ideal for standard forward-mount installations that require a secure, direct fit into threaded machine housings.

The 330101-00-30-50-02-00 variant is distinctively configured with a 5.0-meter (16.4 feet) total length standard cable, allowing it to interface directly with a 5-meter Proximitor sensor without the need for an intermediate extension cable. This direct-connect configuration reduces physical connection points, simplifying the measurement loop and increasing system reliability. Equipped with a miniature coaxial ClickLoc connector and standard FEP-insulated triaxial cable, this unarmored probe provides robust mechanical stability and high chemical resistance in demanding industrial environments.

Features

• Eddy-current measurement principle for non-contact, wear-free shaft vibration and position monitoring.
• Direct-connect 5.0-meter total cable length, engineered specifically for direct pairing with 5-meter Proximitor sensors.
• Fully threaded 3.0-inch case length (0.0-inch unthreaded) with standard 3/8-24 UNF-2A threads for precise adjustment.
• Rugged polyphenylene sulfide (PPS) probe tip and AISI 303/304 stainless steel body for harsh machine environments.
• Standard unarmored FEP-insulated coaxial cable for excellent flexibility and resistance to corrosive industrial fluids.
• Miniature coaxial ClickLoc connector ensures a secure, reliable electrical connection with minimal signal degradation.

Applications

• Steam and gas turbine shaft vibration and axial position measurement.
• Rotor displacement monitoring in centrifugal compressors, expanders, and industrial pumps.
• Generator bearing oil film clearance and shaft dynamic motion analysis.
• Machine speed and Keyphasor reference measurements on high-speed rotating equipment.
• Permanent machine protection in power generation, oil and gas, and petrochemical facilities.

Technical Specifications

Installation Guidelines

• Ensure the probe is mounted with the appropriate probe gap set in accordance with system calibration (typically 1.27 mm or 50 mils for standard linear range).
• Ensure the mechanical mounting location does not exceed maximum rated torque limits when tightening the probe case into the machine housing. Standard recommended torque is 11.2 N-m (100 in-lbf).
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) during routing to prevent internal damage to the coaxial core and shield.
• Always route the probe cable away from sources of high-frequency electromagnetic interference and use proper shielding and grounding practices.
• This 5.0-meter probe must be connected directly to a 5-meter Proximitor sensor only; do not add an extension cable to this configuration as it will alter the system's electrical length and disrupt calibration.

Compliance and Certifications

This product is designed and manufactured in accordance with strict industrial quality standards. For this specific non-approved configuration (Option E: 00), hazardous area certifications are not included. The probe is intended for general-purpose industrial environments where explosive atmospheres are not present.
