Bently Nevada 330103-00-06-50-02-00 3300 XL Proximity Probe

Description

Option 00 (0 mm unthreaded length) and Option 06 (60 mm overall case length) specify this metric 3300 XL 8 mm proximity probe configuration — 330103-00-06-50-02-00. This non-contact eddy-current sensor is used for shaft vibration, axial position, and speed measurements on rotating machinery. With an M10 x 1 metric thread and no protective armor, this standard forward-mounted probe includes a 5.0-meter total cable length ending in a miniature coaxial ClickLoc connector. This specific 5-meter total length matches a 5-meter Proximitor sensor directly, eliminating the need for an intermediate extension cable in standard installations.

Unlike variants with armored casing or protective connector sleeves (such as Option 01), this model features a standard unarmored 75-ohm coaxial cable with a fluorinated ethylene propylene (FEP) jacket, which is suitable for standard conduit installations. Since Option 00 specifies "Not Required" for agency approvals, this unit is intended for non-hazardous industrial areas or general-purpose testing environments. It offers an 80 mil (2.0 mm) linear measurement range when configured with a calibrated 3300 XL Proximitor sensor and AISI 4140 steel target.

Features

• Option 00 fully threaded metric M10 x 1 case with 0 mm unthreaded length
• Option 06 overall case length of 60 mm constructed from 303 stainless steel
• Option 50 total cable length of 5.0 meters (16.4 feet) for direct sensor connection
• Option 02 miniature coaxial male ClickLoc connector without connector protector
• Option 00 standard configuration with no hazardous area approvals required
• FEP-insulated coaxial cable with a minimum bend radius of 25.4 mm (1.0 inch)
• TipLoc molding process provides a secure bond between the 8.0 mm probe tip and stainless steel case
• CableLoc design delivers 330 N (75 lbf) pull strength between probe case and cable

Applications

Typical application scenarios include:

• Radial vibration measurements on fluid-film bearing machines
• Thrust position measurements on steam and gas turbines, compressors, and gearboxes
• Shaft rotational speed and keyphasor reference tracking
• General rotating machinery protection and condition monitoring in non-hazardous industrial areas

Installation Guidelines

Standard engineering practices should be followed during installation of the M10 x 1 metric probe:

• Observe the minimum bend radius of 25.4 mm (1.0 in) for standard probe cables during routing to prevent core damage.
• Ensure the probe mounting location is clean and free of metal debris to prevent interference with the eddy-current field.
• Avoid over-tightening the probe case; the maximum rated torque for an M10 x 1 standard mount probe is 22.6 N-m (200 in-lbf).
• Set the correct initial physical gap (typically 1.27 mm or 50 mils) using a caliper or multimeter DC voltage output from the Proximitor sensor.
• Avoid using a standard 5.0-meter probe with an additional extension cable unless configuring a specific 9-meter overall system with compatible elements. Always match probe and cable lengths to the sensor requirements.
