Configured for signal transmission in mechanical monitoring networks, the Bently Nevada 330130-040-02-00 (330130 3300 XL Extension Cable) serves as a dedicated hardware component for bridging the electrical connection between proximity probes and signal conditioning instrumentation. This component provides the necessary transmission path for high-frequency eddy-current signals while maintaining the impedance characteristics required for accurate rotor displacement and vibration analysis.

Model Identification Matrix

The 330130-040-02-00 designation represents the following physical configuration:

• Cable Length: 4.0 meters (13.1 feet).

• Cable Construction: Standard cable with integrated connector protectors.

Hardware Specifications

Mechanical Signal Dynamics

The 3300 XL transducer system utilizes eddy-current proximity sensing to translate physical displacement into measurable electrical signals. To maintain the accuracy of rotor dynamics, including shaft centerline and orbital vibration data, the system requires precise eddy-current probe scaling. Technicians must perform gap voltage validation during system commissioning, ensuring the output is approximately -10 VDC when the probe is centered in the linear range. To prevent measurement errors, effective cross-talk suppression must be maintained by physically isolating extension cables from high-power AC lines or motor leads, which otherwise introduce electromagnetic noise into the signal chain.

Installation Guidelines

• Conduit Routing: Secure the cable within grounded metallic conduit to provide shielding from external electromagnetic interference (EMI).

• Bend Limits: Observe a minimum bend radius of 25.4 mm during installation to maintain the structural integrity of the coaxial dielectric.

• Connector Maintenance: Fasten connectors finger-tight; the use of mechanical tools for tightening risks damaging internal pin alignment or locking threads.

• Moisture Protection: Use the integrated connector protectors in high-humidity or oil-mist environments to prevent oxidation and resistive signal losses at contact points.

Shipping & Logistics

Frequently Asked Questions

• What material targets are supported? The transducer loop is factory-calibrated for AISI 4140 steel. Using other target materials requires site-specific scale factor adjustments to ensure measurement linearity.

• What is the probe sensitivity? The 3300 XL system, including this extension cable, operates at a constant sensitivity of 7.87 V/mm (200 mV/mil).

• How often should calibration be verified? Verification of loop resistance and signal integrity is recommended during major maintenance outages or if the monitoring system reports persistent signal drift.

• Can the probe operate in hazardous environments? This cable is compatible with hazardous area loops provided the entire system, including the probe and proximity sensor, is installed according to certified control drawings.

• What extension cables are compatible? Only Bently Nevada 3300 XL series cables are compatible. Mixing incompatible cable lengths or impedance ratings results in signal attenuation and inaccurate vibration data.

• What causes unstable gap voltage? Unstable signals are typically caused by loose cable connections, degraded coaxial shielding, or ground loops established by improper conduit grounding.

• How is probe health tested? Health is validated by checking the static loop resistance and confirming the dynamic output frequency response at the monitor rack using a calibrated simulator.

• What is the expected service life? Service life is subject to the operating environment, including thermal and mechanical stress. The cable is designed for continuous, long-term duty under rated conditions.
