Bently Nevada 330106-05-30-10-02-05 3300 XL 8 mm Reverse Mount Proximity Probe

Description

330106-05-30-10-02-05 specifies this 3300 XL 8 mm reverse mount proximity probe configuration, which features metric M10 x 1 threads, an unthreaded case length of 5.0 mm (Option 05), an overall case length of 30 mm (Option 30), a 1.0-meter total cable length (Option 10), standard ClickLoc coaxial connector (Option 02), and CSA/ATEX/IECEx hazardous area approvals (Option 05).

In contrast to sibling configurations like the 330105 which uses 3/8-24 UNF imperial threads, this metric variant uses M10 x 1 threads. While other options in this family may specify armored cabling or FluidLoc fluid barrier protection (such as Option 12), this standard configuration provides a non-armored standard coaxial cable with a miniature ClickLoc connector. It is calibrated for a standard 80 mil (2.0 mm) linear range when paired with a matching 3300 XL extension cable and Proximitor sensor.

Features

• M10 x 1 threaded metal body designed specifically for rear-mounting installations.
• Option 05 unthreaded length of 5.0 mm (0.20 in) optimizes positioning within mounting sleeves.
• Option 30 overall case length provides 30 mm (1.2 in) of thread engagement depth.
• Option 10 specifies a 1.0-meter (3.3 feet) total probe length.
• Option 02 provides a miniature gold-plated coaxial ClickLoc connector on standard coaxial cable.
• Option 05 certification package covers CSA, ATEX, and IECEx hazardous area installations.
• Backward compatible with standard non-XL 3300 series 5 mm and 8 mm components.

Applications

• Shaft vibration and axial position measurements on high-speed rotating machinery.
• Fluid-film bearing monitoring in steam turbines, gas turbines, compressors, pumps, and industrial motors.
• Keyphasor phase reference and rotational speed measurements.
• Reverse mount installations utilizing a probe sleeve or bracket where access to the front of the machine is restricted.

Installation Guidelines

Proper installation of the 3300 XL reverse mount probe is critical for accurate eddy-current displacement monitoring. Observe the following physical and electrical installation guidelines:

• Target Gap: Mechanical gapping should place the probe tip within the linear operating range (normally around 1.25 mm or 50 mils from the target surface, yielding approximately -10 VDC on the Proximitor sensor output).
• Thread Torque: Tighten the reverse-mount body into its mounting sleeve finger tight, then apply torque not exceeding 4.5 N-m (40 in-lb) for M10 x 1 threads to avoid damaging the case.
• Connector Care: Hand-tighten the ClickLoc coaxial connector. Ensure the connection is clean and dry. Use a connector protector if there is exposure to fluids.
• Sleeve Fit: Reverse-mount probes are typically installed in a sleeve with a matching female thread. Maintain a minimum clearance around the probe tip to prevent cross-talk or side-wall interference.
