Configured for specific mechanical displacement monitoring within Turbine Supervisory Instrumentation (TSI) networks, the Bently Nevada 330103-00-03-50-02-00 (330103 Proximity Probe) provides direct physical/electrical execution. It transforms the physical gap between the probe tip and the target rotating shaft into a proportional analog electrical signal, enabling continuous observation of critical machine conditions.

System Configuration Breakdown

• Base Model (330103): 3300 XL 8 mm proximity probe with M10 x 1 thread, unarmored.

• Unthreaded Length Option (00): 0 mm.

• Overall Case Length Option (03): 30 mm.

• Total Length Option (50): 5.0 meters (16.4 feet).

• Connector and Cable Type Option (02): Miniature coaxial ClickLoc connector, standard cable.

• Agency Approval Option (00): Not required.

Physical and Electrical Parameters

Rotor Dynamics and Eddy-Current Calibration

The eddy-current probe scaling for this 8 mm system yields a standard linear range of 2.0 mm (80 mils). Accurate gap voltage validation is required during installation to place the target material in the center of this linear region, typically yielding a -10 VDC target voltage at the Proximitor output. This precise calibration prevents signal distortion and minimizes cross-talk suppression issues when multiple probes are installed in close proximity along the rotor shaft, ensuring high-fidelity tracking of high-speed vibration profiles.

Technical Query Resolution

Q: What is the significance of the 5.0 meter total length option for the Proximitor system matching?

A: The 3300 XL 8 mm probe must match the total electrical length required by the Proximitor Sensor. A 5.0 meter probe must be paired exclusively with a 5.0 meter Proximitor system without any additional extension cables, or used in a combination that sums exactly to the system's calibrated length to prevent calibration drift.

Q: Can this unarmored standard cable withstand direct immersion in industrial lubricants?

A: Yes. The standard cable insulation is chemically resistant to standard turbine oils and industrial lubricants. However, without the optional stainless steel armor, the cable must be routed inside a protective conduit or internal machine housing to prevent mechanical shearing or pinching.

Q: What is the mechanical torque limit for installing this M10 x 1 threaded case?

A: The maximum installation torque for the M10 x 1 case option is 7.5 N-m (66 in-lb). Exceeding this value risks stripping the thread or damaging the internal coil assembly within the probe tip.

Mechanical Installation and Grounding Protocols

• Thread Engagement: Ensure a minimum of 5 full threads of engagement into the mounting bracket or machine housing to guarantee structural stability against operational vibration.

• Gap Calibration: Utilizing a calibrated digital voltmeter linked to the Proximitor Sensor output terminal, adjust the physical probe position until the gap voltage reaches the desired -10 VDC nominal center point (corresponding to the mid-point of the linear operational range).

• Isolation and Grounding: The miniature coaxial ClickLoc connector must be electrically isolated from the machine housing. Use the supplied protective connector sleeves to prevent parasitic ground loops. System shielding must terminate exclusively at the control rack or safety barrier ground point.

• Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the standard coaxial extension cable during routing to prevent core damage and signal attenuation.

Logistics and Kit Composition
