Bently Nevada 330101-00-20-20-12-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length), Option 20 (2.0 in case length), Option 20 (2.0 m total length), Option 12 (ClickLoc connector, FluidLoc cable), and Option 05 (CSA/ATEX/IECEx approvals) specify this 3300 XL 8 mm proximity probe configuration — 330101-00-20-20-12-05.

This configuration incorporates a FluidLoc cable that blocks oil or other process fluids from leaking out of the machine housing through the internal wire paths, distinguishing it from standard cable variants (such as Option 02). Featuring a fully threaded 3/8-24 UNF steel body without armor, the probe mounts permanently on bearing housings or casings. It functions within the 3300 XL 8 mm Proximity Transducer System, pairing with a 330180 Proximitor sensor and a 330130 extension cable to achieve a total 5.0 m or 9.0 m system length. The probe operates on the eddy-current principle to provide non-contact displacement measurements for shaft vibration and axial position monitoring.

Features

• Option 00 unthreaded length specifies a fully threaded probe body configuration.
• Option 20 case length provides a 2.0 in (50.8 mm) threaded housing for standard mounting brackets.
• Option 20 total length provides a 2.0 m (6.6 ft) integrated cable.
• Option 12 cable provides FluidLoc technology to prevent fluid leakage along the cable interior.
• Option 05 agency approval certifies the probe for CSA, ATEX, and IECEx hazardous area environments.
• 3/8-24 UNF-2A thread design secures the probe directly into threaded ports without armor.
• Gold-plated ClickLoc coaxial connector provides a secure connection that clicks when tight.

Applications

• Steam and gas turbine shaft vibration and position monitoring
• Compressor and pump rotor displacement measurements
• Critical rotating machinery protection and diagnostics
• Hydroelectric turbine shaft runout and thrust position tracking

Installation Guidelines

Mount the probe with the appropriate probe gap as specified by system calibration (typically 1.27 mm or 50 mils for a 2.00 mm linear range). Ensure the minimum unthreaded length and overall case length match the installation port to prevent bearing contact. Route the probe cable using proper shielding and grounding practices to prevent electromagnetic interference. Observe the minimum cable bend radius of 25.4 mm (1.0 in) during installation to prevent internal conductor damage. Do not exceed the maximum rated installation torque of 22.6 N-m (200 in-lbf) during threaded casing installation.
