Configured for high-precision displacement sensing in industrial monitoring platforms, the Bently Nevada 102044-00-28-10-02-00 (102044 Proximity Probe) provides direct physical signal transduction of rotor position and vibration within mechanical clearances.

Model Matrix and Configuration

The 102044-00-28-10-02-00 part number denotes an 8 mm transducer system calibrated for a 1 meter total system length. This configuration ensures impedance matching between the probe, extension cable, and monitoring system to maintain signal linearity.

Hardware Specifications

Mechanical Monitoring and Signal Integrity

The 3300 XL 8 mm system utilizes eddy-current probe scaling to convert target movement into precise voltage variations. Optimal measurement performance requires gap voltage validation during installation to confirm the sensor tip is positioned within the linear -10 VDC target range. The system design incorporates cross-talk suppression, enabling high-density sensor mounting while isolating vibration data from potential interference sources, which preserves the accuracy of shaft centerline and dynamic signal analysis.

Field Installation Guidelines

• Mounting

• Secure the probe in a rigid, grounded mounting bracket to avoid resonant vibration coupling.

• Adjust the probe gap until the output voltage reaches the nominal -10 VDC setpoint at the monitor rack.

• Signal Cabling

• Use shielded coaxial cabling and ensure the shield is terminated at the monitoring system's ground point.

• Avoid sharp cable bends, especially near the connector-to-probe interface, to prevent mechanical fatigue.

Frequently Asked Questions

• What is the primary purpose of this 8 mm probe?

  The probe is designed for non-contact measurement of shaft vibration and position in rotating machinery, utilizing eddy-current principles for accurate displacement sensing.

• Can I replace the integral cable?

  No, the cable is factory-calibrated as an integral component of the probe/extension system; modifying it will degrade system accuracy and invalidate the calibration.

• Is this probe compatible with standard 3300 XL Proximitors?

  Yes, this probe is fully compatible with 3300 XL 8 mm Proximitor sensors, provided the system length matches the factory calibration.

• What happens if the gap voltage is outside the -10 VDC range?

  If the gap is incorrect, the sensor may operate outside its linear range, leading to signal clipping or distorted displacement readings.

• What is the maximum operating frequency?

  The system frequency response extends from 0 to 10 kHz (-3 dB), allowing for both static position and high-speed dynamic vibration monitoring.

• Does this sensor require external power?

  The sensor is loop-powered by the Proximitor at -17.5 V dc to -26 V dc; no separate power supply is required at the probe location.

• How do I identify a good connection?

  Verify signal continuity by measuring the DC voltage at the monitor input; the signal should be stable and within the range of -2 V dc to -18 V dc.

• Why is the sensitivity specified as 200 mV/mil?

  This sensitivity is a standard for Bently Nevada 8 mm eddy-current systems, ensuring that 0.001 inches of movement results in a 200 mV change in the output voltage.
