Description

The Bently Nevada 330101-00-13-15-02-00 is an unarmored, non-contact 8 mm Proximity Probe designed for highly precise machinery vibration and shaft position monitoring. This specific configuration features a fully threaded 3/8-24 UNF stainless steel case with 0.0 inches of unthreaded length and a 1.3-inch overall case length. It is equipped with a 1.5-meter (4.9 ft) standard coaxial cable and is terminated with a miniature coaxial ClickLoc connector. Operating on the eddy current principle, the probe accurately measures dynamic shaft vibration, axial displacement, and rotation speed without any physical contact with the target surface.

As a critical element in Bently Nevada 3300 XL machinery protection systems, this probe is designed to work in conjunction with a 330180 Proximitor sensor and an extension cable. The sensor system translates physical gap changes between the probe tip and a target material (such as AISI 4140 steel) into a continuous, linear analog voltage signal. This non-approvals standard variant is optimized for quick installation in non-hazardous plant sections, ensuring rugged and highly stable performance on bearing housings of steam turbines, gas turbines, compressors, and high-pressure pumps.

Features

• 8 mm probe tip diameter optimal for non-contact machinery displacement and axial vibration monitoring.
• Fully threaded 3/8-24 UNF stainless steel body with 0.0 inches of unthreaded length and a 1.3-inch overall case length.
• Standard unarmored coaxial cable configuration with a total length of 1.5 meters (4.9 feet).
• Miniature coaxial ClickLoc gold-plated connector ensures a robust high-frequency connection to the extension cable.
• Standard industrial design with no hazardous area agency approvals required, simplifying installation in general plant areas.
• High environmental resilience with complete pressure sealing to withstand steam, moisture, and chemical exposure on machine casings.

Applications

• Steam and gas turbine shaft dynamic radial vibration and axial position measurement.
• Industrial compressor and pump rotor displacement monitoring.
• Permanent bearing casing mounting for continuous rotating machinery health protection.
• Balance-of-plant (BOP) machinery requiring accurate non-contact proximity detection.

Installation Guidelines

• Set the appropriate physical gap between the probe tip and the target surface (typically gapped at -9 Vdc or 1.27 mm / 50 mils).
• Ensure the 3/8-24 UNF threaded casing does not exceed a maximum thread engagement of 0.563 inches (14.3 mm) during assembly to prevent mechanical binding.
• Route the coaxial cable through protective conduits, ensuring standard industrial shielding and grounding to prevent electrical noise coupling.
• Avoid installing the probe in environments where the cable will experience bending tighter than its minimum bend radius or high mechanical friction.
• Ensure that the target surface and probe tip are completely clear of magnetic or conductive grease, filings, or heavy residues.

Compliance and Certifications

• Compliant with general industrial rotating machinery safety standards.
• CE compliant.
• RoHS compliant.
