Bently Nevada 330102-04-45-50-01-00 3300 XL 8 mm Proximity Probe

Description

Steel probe case with 3/8-24 UNF threads featuring a 0.4 in unthreaded length (Option 04) and a 4.5 in overall case length (Option 45) — 330102-04-45-50-01-00 proximity probe.

Equipped with stainless steel armor for robust mechanical protection, this configuration includes a miniature coaxial ClickLoc connector with an integrated connector protector (Option 01). The 5.0-meter total length (Option 50) means the probe connects directly to a 5-meter 3300 XL Proximitor sensor, eliminating the need for a separate extension cable. Operating as an eddy-current system, it provides continuous shaft vibration, axial position, and speed measurements on rotating machinery.

Features

• 3/8-24 UNF threaded steel probe case with robust stainless steel armor.
• 0.4 in unthreaded length (Option 04) for precise clearance adjustment.
• 4.5 in overall case length (Option 45).
• 5.0 m total length (Option 50) designed to connect directly to a matching 5-meter Proximitor sensor.
• ClickLoc coaxial connector featuring a fluorosilicone connector protector (Option 01) to seal out moisture.
• Unapproved variant (Option 00) for standard non-hazardous industrial environments.

Applications

• Steam and gas turbine shaft vibration and position monitoring.
• Hydroelectric turbine shaft displacement tracking.
• Boiler feed pump axial position thrust measurements.
• Large industrial compressor and blower vibration protection.
• Gearbox shaft dynamic motion monitoring.

Installation Guidelines

• Secure the probe housing using a 9/16 inch lock nut (supplied).
• Verify that the unthreaded length is at least 0.8 in less than the overall case length to maintain physical housing stability.
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) to prevent damaging the internal coaxial core and outer armor.
• Hand-tighten ClickLoc connectors to click feedback. Do not use tools on the gold-plated connectors.
• Run probe cables through dedicated, grounded conduits to avoid electromagnetic interference.
