Configured for non-contacting vibration and displacement measurement in 3300 XL monitoring platforms, the Bently Nevada 330130-085-02-CN (330130-085-02-CN Proximity Probe) provides direct physical/electrical execution for monitoring radial and axial shaft motion.

Suffix Breakdown and Model Configuration

The 330130 series is engineered as a component of the 3300 XL transducer system. The suffix "-085-02-CN" denotes specific physical length, connector termination, and regional compliance standards. This model facilitates integration into standard proximity probe housing assemblies, maintaining consistency with system-wide impedance requirements.

Hardware Technical Specifications

Transducer System Signal Integrity

Reliable measurement is predicated on accurate eddy-current probe scaling. During installation, gap voltage validation (-10 VDC targets) is mandatory to confirm the probe is operating within the linear region of the transducer curve. Rotor dynamics analysis requires that the probe is mounted securely to mitigate mechanical resonance. Furthermore, proper cross-talk suppression is achieved by ensuring the coaxial shielding remains continuous and is grounded at the monitor end, preventing electrical noise interference in the signal path.

Frequently Asked Questions

• Can this probe be used in 3300 standard (non-XL) systems? No, 3300 XL components are impedance-matched for 3300 XL Proximitor sensors; intermixing will result in measurement errors.

• What is the sensitivity of the system? The system provides a standard sensitivity of 200 mV/mil (7.87 V/mm).

• Can the cable be shortened in the field? No, field modification of the cable length alters system capacitance and invalidates factory calibration.

• Why is the probe tip made of PPS? PPS provides excellent thermal stability and resistance to chemicals common in turbomachinery environments.

• Is the connector waterproof? The connectors are designed to be weather-resistant when mated but are not intended for full liquid submersion.

• How do I identify a ground loop? Presence of 50/60 Hz hum on the output signal often indicates a ground loop or improper shield grounding.

• Can I mount the probe on a curved surface? The probe must be mounted to a flat surface or a specifically designed bracket to ensure perpendicularity.

• What happens if the probe case is dented? Structural damage to the case may indicate internal coil deformation, requiring immediate sensor replacement.
