Hardware Specifications

Rotor Dynamics and Gap Voltage Validation

Engineered to capture precise radial vibration and axial position parameters, the probe maintains strict eddy-current probe scaling to convert target proximity into a linear voltage output. Gap voltage validation targets a nominal -10 VDC baseline when paired with matching 3300 XL Proximitor sensors and extension cables. Furthermore, integrated coaxial shielding combined with stainless steel armor execution ensures cross-talk suppression and mitigates electromagnetic interference across multi-channel industrial turbine instrumentation tracks.

Scope of Delivery Manifest

• 1 x Bently Nevada 330104-01-15-50-02-05 3300 XL 8 mm Proximity Probe
• 1 x M10 x 1 Mounting Locknut Set
• 1 x Hazardous Area Certification Insert

Mechanical Installation Guidelines

• Thread Engagement Limits: Ensure the mounting hole is clean and that maximum thread engagement of the M10 x 1 probe case does not exceed 15 mm.
• Torque Specifications: Tighten the probe housing to a recommended torque of 5.1 N m (45 in lb), ensuring the limit does not exceed 7.3 N m (65 in lb) to prevent structural thread deformation.
• Transducer Separation: Maintain a minimum radial separation of 25 mm (1.0 inch) between adjacent transducer tips to avoid electromagnetic cross-talk interference during multi-probe configurations.

Frequently Asked Questions

• What is the probe tip diameter for this model?

  The probe utilizes a standard 8.0 mm tip diameter designed for eddy-current proximity measurements.

• What type of mechanical cable protection is included?

  The assembly features an integrated stainless steel protective armor jacket surrounding the coaxial cable.

• What is the total physical length specified by the part number?

  The total system cable length is 5.0 meters (16.4 feet) as designated by the model configuration options.

• Does this passive sensor require an external DC power source?
