Description

Configured for non-contact displacement and vibration measurements in machinery health platforms, the Bently Nevada 330104-00-14-05-02-00 (330104 Proximity Probe) provides direct physical/electrical execution. This specialized hardware component converts the physical distance between the probe tip and a rotating conductive target into a corresponding radio frequency feedback voltage loop.

Hardware Specifications

Transducer Interface & Mechanical Monitoring Characteristics

The proximity probe generates a precise eddy-current probe scaling profile when targeting conductive metals such as AISI 4140 steel. The integrated cable and tip layout maintain consistent electrical impedance to ensure highly accurate gap voltage validation (-10 VDC targets) at the midpoint of the linear range. Furthermore, the specialized internal coil geometry establishes high baseline cross-talk suppression against adjacent sensors, isolating side-wall interference from the high-fidelity analog loops that capture dynamic rotor dynamics.

Frequently Asked Questions

Q: Can a 0.5-meter probe connect directly to a standard 3300 XL Proximitor Sensor without an extension cable?

A: No, because the Proximitor sensor internal oscillator requires a strict matched electrical length calibration. Technicians must connect a matching 4.5-meter or 8.5-meter extension cable to achieve the required 5.0-meter or 9.0-meter total system length tuning.

Q: How does the interlocking armor affect the minimum installation bend radius of the cable assembly?

A: The stainless steel interlocking armor protects the internal coaxial line from physical pinching but restricts flexibility. Consequently, technicians must observe a minimum bend radius limitation of 25.4 mm during conduit installation to avoid internal layer deformation.

Field Installation Guidelines

1. Thread the metric probe case into the bracket entry port by hand until the tip approaches the calibrated physical gap distance from the target shaft face.
2. Adjust the final positioning mechanically while monitoring output values to match the target -10 VDC gap voltage parameter.
3. Apply a maximum tightening torque specification of 7.5 N m to the primary locknuts to secure the fully threaded M10 x 1 case without stripping the threads.
4. Align the gold-plated brass ClickLoc coaxial connections and join them firmly until an audible physical click registers positive mechanical retention.
