Bently Nevada 330101-00-40-05-02-05 3300 XL 8 mm Proximity Probe

Description

330101-00-40-05-02-05 specifies this 3300 XL 8 mm proximity probe configuration with a fully threaded 3/8-24 UNF body (0.0 in unthreaded length), 4.0 in overall case length, a 0.5 m (1.6 ft) total length standard cable, a miniature coaxial ClickLoc connector, and CSA, ATEX, and IECEx hazardous area approvals.

This unarmored probe configuration is used for non-contact shaft vibration and axial position measurements in rotating machinery. Unlike armored configurations, this standard-jacket cable provides flexible routing within protective conduits, and its 0.5-meter length is selected for installations requiring a short cable lead before connecting to a longer extension cable. It operates on eddy-current displacement principles, sending physical gap changes as high-frequency electrical signals to a matching 3300 XL Proximitor sensor.

Features

• Fully threaded 3/8-24 UNF steel probe body without armor
• 0.0 inches (0.0 mm) unthreaded length for flush-mount bearing housing installations
• 4.0 inches (101.6 mm) overall case length
• 0.5 meter (1.6 feet) standard coaxial cable with a miniature ClickLoc connector
• CSA, ATEX, and IECEx approvals for installation in hazardous environments
• 8 mm tip diameter for eddy-current displacement measurements
• Viton O-ring pressure seal built into the probe tip and case joint

Applications

• Steam and gas turbine shaft vibration and rotor position monitoring
• Compressor and pump rotor displacement measurements
• Permanent bearing housing and machine casing installations
• Rotating machinery protection systems matching API 670 requirements

Installation Guidelines

• Mount the probe with the appropriate gap distance (typically 1.27 mm or 50 mils) corresponding to system calibration.
• Route the standard coaxial cable through a protective conduit to prevent mechanical wear and isolate it from electromagnetic interference.
• Ground the coaxial cable shield at the Proximitor sensor end only, keeping the shield isolated from the machine housing.
• Ensure the selected unthreaded length and overall case length allow sufficient thread engagement while preventing target interference.

Compliance and Certifications

• CSA Certified
• ATEX Zone 0, Zone 1, and Zone 2 Certified
• IECEx Certified
• CE Compliant
