Bently Nevada 330103-10-18-50-01-00 3300 XL 8 mm Proximity Probe

Description

330103-10-18-50-01-00 specifies a metric thread, unarmored 3300 XL 8 mm proximity probe used as part of Bently Nevada non-contacting eddy-current transducer systems. This configuration features an M10 x 1 thread with a 100 mm unthreaded length (Option 10) and a 180 mm overall case length (Option 18). It is equipped with a 5.0-meter (16.4 feet) total length cable (Option 50), terminated in a miniature coaxial ClickLoc connector with a connector protector (Option 01). No hazardous area agency approvals are selected (Option 00) for this unit.

The 5.0-meter probe pairs with a 5.0-meter total length 3300 XL Proximitor sensor, as the cable and probe lengths must match the designated system length for calibrated operation. Since it is constructed without armor, this model is used in installations where cable routing occurs entirely within conduits, protective trays, or internal machinery casings where mechanical abrasion risks are minimized. The M10 x 1 metric thread is used in machinery designs requiring metric standard mounting threads instead of imperial options.

Features

• M10 x 1 Metric Thread: Provides standardized metric mounting interface without armor on the probe lead.
• 100 mm Unthreaded Case Length: Option 10 provides a 100 mm unthreaded region, allowing adjustable depth insertion inside machinery housings.
• 180 mm Overall Case Length: Option 18 provides 180 mm of overall threaded case length for deep mounting port penetration.
• 5.0 Meter Total Length: Option 50 provides a 5.0-meter probe cable, eliminating the need for separate extension cables in short-run layouts when paired with a matching 5-meter Proximitor.
• ClickLoc Connector with Protector: Option 01 terminates the probe in a miniature coaxial ClickLoc connector pre-fitted with a connector protector to prevent environmental exposure and ingress.
• Unarmored Design: Reduced cable diameter profile allows easier routing through narrow pathways and internal conduits.

Applications

The Bently Nevada 330103 series proximity probes are used for static and dynamic machinery measurements in heavy industries. Common applications include:

• Radial shaft vibration and shaft position monitoring in steam turbines, gas turbines, and large industrial compressors.
• Axial thrust position and casing expansion tracking.
• Rotational speed and phase reference (Keyphasor) monitoring.
• Machinery protection systems requiring metric mounting thread integration.

Installation Guidelines

Ensure correct implementation during mechanical installation by adhering to the following guidelines:

• Verify the case thread engagement length does not exceed 15 mm for the M10 x 1 mounting thread to prevent binding.
• Do not exceed the maximum tightening torque limit of 12 N-m (110 in-lb) when mounting the probe.
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) to prevent damage to the inner coaxial conductor.
• Grounding of the outer coaxial shield must be maintained through proper connection to the system ground at the Proximitor sensor end.
• Ensure the probe total length (5.0 m) matches the calibrated length of the Proximitor sensor in the loop.
