Bently Nevada 330101-20-36-10-02-00 3300 XL 8 mm Proximity Probe

Description

330101-20-36-10-02-00: 3300 XL 8 mm proximity probe, 3/8-24 UNF thread, featuring a 2.0 inch unthreaded length (Option 20) and a 3.6 inch overall case length (Option 36). This specific transducer configuration is equipped with a 1.0 meter standard coaxial cable (Option 10) terminated in a miniature ClickLoc connector (Option 02), requiring no hazardous area certifications (Option 00).

Used for non-contact vibration and shaft position measurements, this probe pairs with a 3300 XL Proximitor sensor and extension cable to form a complete 3300 XL monitoring chain. The unarmored design simplifies routing in protected conduit or inside machine casings, while the 3/8-24 UNF thread provides standard mounting compatibility in bearing housings or machine casings.

Features

• Option 20 specifies a 2.0 inch (50.8 mm) unthreaded length.
• Option 36 specifies a 3.6 inch (91.4 mm) overall case length with 3/8-24 UNF thread.
• Option 10 provides a 1.0 meter (3.3 feet) total cable length.
• Option 02 designates standard unarmored coaxial cable with a gold-plated miniature ClickLoc connector.
• Option 00 specifies that agency approvals are not required for this configuration.
• 8 mm probe tip diameter supports non-contact eddy-current displacement measurements.
• Rugged PPS composite tip and stainless steel probe body withstand industrial environments.

Applications

• Steam and gas turbine shaft vibration and axial position monitoring.
• Compressor and pump rotor displacement measurements.
• Permanent bearing housing and machine casing mounting for rotating machinery protection.

Installation Guidelines

Mount the probe with the appropriate probe gap per system calibration (typically 1.27 mm or 50 mils for the 3300 XL 8 mm system). Route the standard coaxial cable using proper shielding and grounding practices to prevent electromagnetic interference in vibration monitoring installations. Observe the maximum thread engagement limit of 0.563 inches (14.3 mm) for 3/8-24 threads during mounting. Ensure that the combined length of the probe and extension cable matches the calibrated total system length of the Proximitor sensor (typically 5.0 meters or 9.0 meters).
