Bently Nevada 330101-00-44-10-02-CN 3300 XL 8 mm Proximity Probe

Description

Engineered for high-precision non-contact shaft vibration and displacement measurements, the Bently Nevada 330101-00-44-10-02-CN is an industrial-grade 3300 XL 8 mm proximity probe. This rugged transducer is designed to operate under demanding environmental conditions, providing stable eddy-current sensor performance for machinery protection systems.

The 330101-00-44-10-02-CN configuration features a 3/8-24 UNF threaded body without protective armor. Key mechanical parameters include an unthreaded length of 0.0 inches (fully threaded case) and an overall case length of 4.4 inches. The probe is equipped with a 1.0-meter (3.3 feet) standard coaxial cable terminated with a miniature coaxial ClickLoc connector. This specific module is compliant with CN country-specific agency approvals, making it suitable for hazardous area installations in designated regions.

Features

• Eddy-current transducer technology for non-contact shaft displacement, vibration, and phase reference measurements.
• Robust polyphenylene sulfide (PPS) tip material offering resistance to chemical degradation and moisture absorption.
• Corrosion-resistant AISI 303 or 304 stainless steel threaded case construction.
• Standard unarmored design with precise 3/8-24 UNF threads for direct mechanical mounting.
• Integrated ClickLoc miniature coaxial connector ensuring secure, low-loss electrical contact.
• Extended operating temperature range for probe and cable components in extreme industrial environments.

Applications

• Steam, gas, and hydro turbines.
• Centrifugal, axial, and reciprocating compressors.
• High-speed process pumps and industrial fans.
• Generators, alternators, and large electric motors.
• Machinery diagnostics, predictive maintenance, and emergency shutdown systems (SIS).

Installation Guidelines

• Ensure target material matches the calibrated standard (typically AISI 4140 steel) for accurate measurement linearity.
• Do not exceed the maximum allowable installation torque for the 3/8-24 UNF stainless steel case to prevent mechanical distortion.
• Maintain minimum side clearance around the probe tip to avoid cross-talk or target edge interference.
• Route coaxial cables through dedicated protective conduit or trays, avoiding sharp bends and high-voltage AC lines.
• Keep ClickLoc connector components dry, clean, and free of oil or contaminants during assembly.

Compliance and Certifications

• CN Country-Specific Safety and Hazardous Area Approvals
• RoHS Compliant
