Bently Nevada 330103-00-03-05-01-05 3300 XL 8 mm Proximity Probe

Description

330103-00-03-05-01-05 specifies a metric-threaded 3300 XL 8 mm proximity probe configuration with an M10 x 1 thread, 0 mm unthreaded length, 30 mm overall case length, 0.5-meter total length, standard cable with miniature coaxial ClickLoc connector and connector protector, and CSA, ATEX, and IECEx agency approvals. This eddy-current probe is used to measure static (position) and dynamic (vibration) displacement on high-speed fluid-film bearing machinery. By generating an output voltage directly proportional to the gap between the probe tip and target target surface, it serves as a reliable sensing device for vibration transmitters, monitoring racks, and speed measurement systems.

In contrast to variants with armored cabling or unthreaded body extensions, this unarmored configuration features a fully threaded metric casing designed for direct installation in threaded machine casings where mechanical protective sleeving is already present or external abrasion hazards are minimal. The integrated connector protector on the ClickLoc interface guards the coaxial link against moisture, dust, and physical tension, helping to prevent signal distortion in critical monitoring loops.

Features

• M10 x 1 metric thread configuration without armor (base model 330103).
• 0 mm unthreaded length option (Option 00) for full thread engagement in compact spaces.
• 30 mm case length option (Option 03) suitable for shallow thread reach requirements.
• 0.5-meter (1.6 feet) total probe length (Option 05) designed to connect with a 4.5-meter extension cable in a standard 5-meter transducer system.
• ClickLoc coaxial connector with connector protector (Option 01) on standard coaxial cable.
• Hazardous area certification package (Option 05) covering CSA, ATEX, and IECEx approvals.
• Fully backward compatible with non-XL 3300 series 5 mm and 8 mm transducer components.
• Probe tip composed of polyphenylene sulfide (PPS) for high chemical and temperature resistance.

Applications

Typical application areas include:

• Vibration and axial position measurements on fluid-film bearing machines such as steam turbines, gas turbines, compressors, and pumps.
• Speed and Keyphasor reference measurements on high-speed rotating industrial machinery.
• Direct replacement or integration in machinery protection systems requiring metric mounting hardware.

Installation Guidelines

Proper installation prevents physical damage and measurement distortion:

• Ensure the probe-to-extension-cable connection is finger tight. Do not use pliers on ClickLoc connectors unless mating with non-XL stainless steel connectors.
• Apply the connector protector sleeve over the connection to guard against moisture and dust ingress.
• Verify that the minimum target area is at least 15 mm in diameter. Side clearance from surrounding metal must be maintained to avoid side-view interference.
• Observe the maximum thread engagement limit of 15 mm for M10 x 1 threads to avoid binding during installation.
• Keep the probe tip clear of metallic debris during operation to prevent false gap readings.
