The 149032-03 is a foundational component of the Bently Nevada 3300 XL Proximity Transducer System. This Proximitor® Sensor acts as the sophisticated signal conditioning brain for eddy current probes. It performs two critical functions: it generates the high-frequency Radio Frequency (RF) signal that excites the probe tip and subsequently converts the returned modulated signal into a usable voltage output.
Specifically calibrated for a 9.0-meter total system length, the 149032-03 delivers a highly linear 7.87 V/mm (200 mV/mil) output proportional to the distance between the probe tip and the observed metal surface. This allows for the non-contact measurement of both static displacement (thrust/position) and dynamic vibration in high-criticality rotating machinery, including steam turbines, centrifugal compressors, and large-scale industrial motors.
The 149032-03 configuration is engineered for seamless integration into 3500 Monitoring Systems or standalone PLC/DCS architectures.
The -03 option indicates a factory calibration for a 9.0-meter (29.5 feet) total system length. To maintain the specified accuracy and Scale Factor, the combined length of the proximity probe and the extension cable must exactly total 9.0 meters.
The 3300 XL hardware architecture provides superior suppression of "radio frequency interference" (RFI). This ensures that the vibration data remains clean even when the sensor is mounted in proximity to high-voltage motor starters or communication equipment.
Constructed with a high-grade zinc-plated or aluminum housing, the 149032-03 resists corrosion and provides a robust shielding against electromagnetic noise. The internal electronics are fully encapsulated to prevent failure from moisture or vibration within the local instrument enclosure.
| Parameter | Specification Value |

| Input Power | -17.5 VDC to -26 VDC |
| Output Sensitivity | 7.87 V/mm (200 mV/mil) |
| Linear Range | 2.0 mm (80 mils) |
| Frequency Response | 0 Hz (DC) to 10 kHz |
| Operating Temperature | -51°C to +100°C (-60°F to +212°F) |

The 3300 XL Proximitor® Sensor offers significant technical improvements over legacy 3300 and 7200 series models:
Complete Interchangeability: The 149032-03 allows for the replacement of probes or cables without the need for on-site recalibration, provided the total system length remains at 9.0 meters.
Improved Scale Factor Stability: The internal circuitry compensates for temperature variations, ensuring that a vibration reading in the heat of summer is just as accurate as one in the dead of winter.
Self-Diagnostic Logic: The sensor maintains a consistent "Not OK" status if the probe circuit is broken or shorted, preventing the monitoring system from providing false "zero-vibration" data during a sensor failure.
Successful deployment depends on correct electrical grounding and physical mounting.
Mount the Proximitor® on a standard 35mm DIN rail or directly to a backplate. For optimal performance, ensure the sensor housing is electrically isolated from the machine ground to prevent ground loops. Use the factory-supplied isolation washers if mounting to a metal plate.
Use high-quality shielded, twisted-pair cable for the connection between the 149032-03 and the monitoring rack. Connect the -VT (Voltage Terminal), COM (Common), and OUT (Signal) terminals precisely. Ensure the shield is grounded at the monitor end only.
After installation, verify the "Gap Voltage" at the PROXIMITOR test points. For a standard 8mm probe, a reading of -10.0 VDC indicates the probe is positioned at the center of its linear range, providing maximum headroom for both vibration and thrust measurements.
Q1: Can I use the 149032-03 with a 5.0-meter cable system?
A1: No. The 149032-03 is specifically calibrated for a 9.0-meter system. Using a 5.0-meter setup will cause a significant Scale Factor error, resulting in vibration readings that are inaccurate by 20% or more. Always match the Proximitor® to your total cable length.
Q2: What is the difference between the 149032 series and the older 330180 Proximitors?
A2: The 149032 is the updated 3300 XL Proximitor® Sensor. While they share similar footprints, the 149032 offers better RFI immunity and improved thermal stability. It is a direct functional replacement for the older 330180-series modules.
Q3: Does this sensor require a separate power supply?
A3: Yes. It requires a stable -24 VDC power source (standard for Bently Nevada systems). This power is usually provided directly from the 3500/M or 3701/M monitoring rack.
Q4: Is the 149032-03 compatible with 11mm or NSv probes?
A4: No. This specific model is designed for use with 3300 XL 8mm probes. 11mm and NSv systems require their own dedicated Proximitor® models due to differences in tip diameter and electrical impedance.
