Bently Nevada 330171-00-12-10-01-05 3300 5 mm Extension Cable

Configured for high-frequency signal transmission in machine monitoring systems, the Bently Nevada 330171-00-12-10-01-05 (330171 5 mm Proximity Probe) provides direct physical execution of displacement sensing within the 3300 series transducer platform. This assembly features a 5 mm probe tip and an integrated connector interface, maintaining the electrical impedance required to preserve signal fidelity between the probe tip and the associated Proximitor sensor.

Suffix Breakdown & Model Matrix

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The 3300 series proximity transducer system is factory-calibrated to output a signal proportional to the distance between the probe tip and the target material. For the 5 mm probe, the standard scaling is 7.87 V/mm (200 mV/mil). During installation, the gap voltage must be validated at the Proximitor sensor terminals; a target of -10 VDC is required to ensure the probe operates at the linear center of its range. Rotor dynamics measurements are susceptible to signal noise if proper cross-talk suppression is not maintained. Ensure all probe leads are routed away from high-current conductors and switching noise sources to prevent the introduction of induced electromagnetic interference into the transducer loop.

Frequently Asked Questions

Q: Is the ClickLoc connector compatible with standard 3300 XL series extension cables?

A: No. The 330171 5 mm probe series utilizes a specific miniature coaxial interface. Attempting to force a connection with XL series components will result in mechanical damage to the connector pins and degraded electrical performance.

Q: What are the restrictions regarding the probe tip material?

A: The probe is factory-calibrated for AISI 4140 steel. If the target material possesses different magnetic permeability or electrical resistivity, the linear scale factor will deviate, and a site-specific calibration curve must be applied to the monitoring system.

Field Installation Guidelines

• Mounting: Ensure the probe is threaded into the mounting bracket until it reaches the desired gap, then secure with the locking nut. Excessive tightening torque may damage the 1/4-28 UNF threads.
• Shielding: Maintain the integrity of the coaxial shield throughout the cable run. The shield must be connected to the system common at the Proximitor sensor terminal block only; do not ground the probe case directly unless specifically required by the monitoring architecture.
• Connector Care: The ClickLoc connector incorporates a protector. Ensure the mating surface is free of debris before snapping the connection into place. The audible "click" indicates proper seating.
• Cable Routing: Do not exceed the minimum bend radius of the coaxial cable during installation. Ensure the cable is supported at regular intervals to prevent mechanical vibration from causing fatigue or connector strain.
