Description

The Bently Nevada 330104-00-24-05-02-00 serves as the primary 330104 Proximity Probe utilized to execute non-contact displacement and vibration measurements across Bently Nevada 3300 XL Series Machinery Protection platforms. Consequently, this non-contacting sensor translates the physical gap variation between the probe tip and a rotating shaft into an analog radio frequency feedback loop.

Hardware Specifications

Transducer Interface & Mechanical Monitoring Characteristics

This probe system establishes a calibrated magnetic field to maintain precise eddy-current probe scaling when targeting industrial materials such as AISI 4140 steel. The physical construction ensures a low-loss signal path to support accurate gap voltage validation (-10 VDC targets) within the center of the calibrated linear range. Furthermore, the internal sensing coil provides native cross-talk suppression against adjacent probe assemblies, isolating external electronic noise from the dynamic waveforms used to evaluate high-speed rotor dynamics.

Frequently Asked Questions

Q: Why must a technician use a matching extension cable with this 0.5-meter proximity probe?

A: The Proximitor sensor internal tuning requires a strict total electrical length matching either 5.0 meters or 9.0 meters. Therefore, connecting a 0.5-meter probe directly without a 4.5-meter or 8.5-meter extension cable causes severe calibration shift and scale factor breakdown.

Q: What are the installation hazards associated with the interlocking stainless steel armor?

A: The armor protects the inner coaxial line from physical damage but introduces a mechanical bend constraint. Forcing the armored section past a minimum bend radius limit of 25.4 mm permanently deforms the internal shielding layer, altering system capacitance.

Field Installation Guidelines

1. Thread the metric probe case into the machined casing hole by hand to prevent cross-threading the M10 x 1 mounting profile.
2. Adjust the probe depth mechanically while evaluating the live DC loop voltage to reach the designated -10 VDC baseline setting.
3. Torque the primary mounting locknuts to a maximum limit of 7.5 N m to ensure mechanical locking without warping the fully threaded body.
4. Clean the gold-plated brass ClickLoc coaxial terminals and press them together firmly by hand until an audible physical click registers positive mechanical engagement.
