Bently Nevada 330103-00-15-10-02-00 3300 XL 8 mm Proximity Probe

Description

330103-00-15-10-02-00 specifies a metric thread configuration of the 3300 XL 8 mm proximity probe, defined by an M10 x 1 threaded body with 0 mm of unthreaded case length (Option 00) and a 150 mm overall case length (Option 15). This unarmored eddy-current sensor is equipped with a 1.0 m total cable length (Option 10) terminated with a miniature coaxial ClickLoc connector (Option 02) and has no hazardous area approvals (Option 00).

In contrast to armored variants or configurations with pre-installed connector protectors, this standard unarmored coaxial probe simplifies routing through metric conduit runs and mounting plates. It operates within a complete 3300 XL 8 mm transducer system, combining with a standard extension cable and Proximitor sensor to provide a continuous voltage output representing dynamic shaft vibration or static axial position on fluid-film bearing machinery.

Features

• Metric M10 x 1 threaded body for mounting directly into metric-tapped machine casings.
• 0 mm unthreaded length (fully threaded case) allows for maximum thread depth adjustment during installation.
• 150 mm overall case length provides deep reach capability for internal machine clearances.
• 1.0 meter total cable length designed to pair with an 8.0 meter standard extension cable for a 9.0 meter total system.
• Standard miniature coaxial ClickLoc connector provides a secure mechanical connection with positive tactile feedback.
• Standard triaxial cable with durable FEP insulation has a 3.68 mm outside diameter and is resistant to corrosive oils.
• 8.0 mm probe tip diameter supports a standard 2.0 mm (80 mils) linear range.
• Wide operating temperature range from -52 degC to +177 degC for high-temperature process conditions.

Applications

This proximity probe is used for non-contact shaft displacement measurements in critical industrial equipment including:

• Industrial steam and gas turbine rotor axial position and dynamic vibration monitoring.
• Centrifugal compressor shaft vibration and thrust position analysis.
• High-speed gearbox shaft radial vibration and speed detection.
• Fluid-film bearing performance and machine protection systems.
• Keyphasor reference and rotational speed measurement applications.

Installation Guidelines

Proper mechanical installation of the probe is essential to ensure measurement accuracy:

• Securely mount the probe to a rigid bracket or machine wall to prevent vibration in the mounting assembly from distorting shaft displacement readings.
• Maintain a minimum thread engagement depth of 15 mm for the M10 x 1 thread to prevent physical damage or loose fittings during machine operation.
• Ensure that the probe tip has an open clearance of at least 3 probe tip diameters (24 mm) from any surrounding target-side metal to avoid electrical interference and calibration bias.
• Set the initial probe gap to approximately 1.27 mm (50 mils) to establish a proper electrical midpoint of -10 Vdc when connected to the Proximitor sensor.
• Route the cable with appropriate bend radii (minimum 25 mm) and secure it to prevent chafing or physical strain on the ClickLoc connector.
• Utilize safety wire through pre-drilled holes in the lock nut to maintain tightening torque under high-vibration conditions.

Compliance and Certifications

This configuration (Option 00) does not include hazardous area approvals. It complies with general CE directives for industrial machinery and electromagnetic compatibility when integrated into a compliant Bently Nevada monitoring system.
