Bently Nevada 330103-12-25-10-01-00 3300 XL Proximity Probe

Description

330103-12-25-10-01-00 specifies a metric-threaded 3300 XL 8 mm proximity probe configured with a 120 mm unthreaded length (Option 12), a 250 mm overall case length (Option 25), and a 1.0-meter total cable length (Option 10). This unarmored probe utilizes an M10 x 1 thread body and is equipped with a miniature coaxial ClickLoc connector featuring a built-in connector protector (Option 01). No hazardous area agency approvals are required for this configuration (Option 00).

This proximity probe operates as an eddy-current transducer to measure static and dynamic shaft displacement. Unlike standard variants that lack connector shielding, this configuration's fluorosilicone connector protector isolates the coaxial connection from grease, moisture, and chemical exposure, preventing signal degradation in harsh environments. The unarmored design provides standard flexibility for cable routing through protective conduits or clean internal machinery passages.

Features

• Metric M10 x 1 threaded case body format without protective armor.
• 120 mm unthreaded length option for targeted positioning.
• 250 mm overall case length option for deep insertion sensor applications.
• Integral 1.0-meter coaxial cable with standard FEP insulation.
• Miniature coaxial ClickLoc connector featuring a fluorosilicone connector protector.
• PPS (Polyphenylene Sulfide) probe tip engineered for thermal stability and chemical resistance.

Applications

This metric proximity probe is typically deployed in heavy industrial environments on rotating machinery. Common applications include:

• Radial vibration and axial shaft position tracking.
• Steam turbines, gas turbines, and centrifugal compressors.
• Keyphasor and phase reference pulse detection.
• Fluid-film bearing clearance monitoring.
• Industrial pump and generator shaft monitoring.

Installation Guidelines

To establish safe electrical and physical performance, follow these standard practices:

• Apply a maximum tightening torque of 3.5 N-m (31 in-lb) for the M10 x 1 threaded body.
• Ensure the maximum depth of thread engagement does not exceed 15 mm.
• Maintain a minimum bend radius of 25.4 mm (1.0 in) for the standard coaxial cable.
• Keep the probe tip at least 16 mm clear of adjacent metal surfaces to prevent interference.
• Ensure the sum of the probe length and standard extension cable matches the 3300 XL Proximitor sensor system requirements (typically 5.0 meters or 9.0 meters total length).
