Bently Nevada 330103-02-08-10-02-00 3300 XL Proximity Probe

Description

Option 02 (20 mm unthreaded length) and Option 08 (80 mm overall case length) specify this 3300 XL 8 mm metric thread proximity probe configuration — 330103-02-08-10-02-00. This unarmored variant features an M10 x 1 threaded body, providing direct-mount capabilities in machinery casings or brackets where external armor is unnecessary or managed independently. The probe functions within an eddy-current transducer system, tracking dynamic shaft vibration, axial position, or keyphasor reference signals on rotating machinery.

This configuration operates with a 1.0-meter (3.3 feet) integrated standard coaxial cable terminated in a miniature male ClickLoc coaxial connector. It connects to a 3300 XL standard extension cable and a 3300 XL Proximitor Sensor, forming a system that measures displacement from a target with a linear range of 2.0 mm (80 mils). Since this model uses Option 00 for agency approvals, it is suited for non-hazardous locations or standard industrial installations requiring no specific flameproof or intrinsically safe certifications.

Features

• Metric M10 x 1 threaded steel case without protective armor, allowing streamlined routing and direct installation into standard metric probe sleeves or tapped housings.
• 20 mm unthreaded body length combined with an 80 mm case length to facilitate precise physical positioning during mechanical gap adjustment.
• 1.0-meter (3.3 feet) standard coaxial cable length optimized for installation inside machine housings before coupling to an external extension cable.
• Miniature gold-plated brass ClickLoc coaxial connector provides a secure, vibration-resistant coupling without the bulk of a connector protector.
• Standard polyphenylene sulfide (PPS) molded tip provides electrical insulation and environmental protection for the internal eddy-current coil.

Applications

• Radial shaft vibration monitoring inside fluid-film bearing housings on steam turbines, gas turbines, and compressors.
• Axial thrust position measurement on high-speed industrial rotating shafts.
• Speed and keyphasor reference tracking on industrial motors, generators, and gearboxes with metric mounting layouts.

Installation Guidelines

• Do not exceed the maximum allowable thread engagement length of 15 mm for M10 x 1 threads during installation.
• Ensure the recommended maximum tightening torque of 5.0 N-m (44 in-lb) is not exceeded to avoid damage to the metric probe case.
• Maintain at least 20 mm clearance around the unthreaded length to prevent side-view metal interference, which can distort the sensor's magnetic field and scale factor.
• Verify that the physical gap is adjusted inside the linear region of the transducer, typically targeted at a nominal DC voltage output of -9 Vdc (approximately 1.27 mm or 50 mils from the target).
• Keep the ClickLoc coaxial connection dry and isolated from lubricating oils or moisture during routing.

Compliance and Certifications

This proximity probe is manufactured to meet commercial standards for machinery monitoring systems. As it features Option 00 (approvals not required), it is intended for non-hazardous area applications. The probe conforms to relevant CE directives and EU RoHS standards.
