3300 XL 288055-02 Proximitor Shaft Vibration Monitoring

Product Overview

The Bently Nevada 288055-02 serves as the sophisticated signal processing core of the 3300 XL Transducer System. This Proximitor® Sensor converts the raw eddy current signals from a proximity probe into a linear voltage output directly proportional to the distance between the probe tip and the observed target (typically a rotating shaft). We supply this unit as 100% Brand New and Original, ensuring seamless compatibility with your existing Bently Nevada 3500 or 2300 monitoring racks.

Technical Specifications

Engineering Advantages

• Optimized Signal Linearity: The 288055-02 eliminates the non-linearities common in eddy current sensing. It provides a highly stable 7.87 V/mm (200 mV/mil) output, allowing for precise tracking of axial thrust and radial vibration.

• Superior EMI Resistance: The ruggedized internal circuitry filters out electromagnetic interference (EMI) and Radio Frequency Interference (RFI). This ensures that electrical noise from nearby motors or variable frequency drives (VFDs) does not corrupt your critical machinery data.

• Simplified Field Calibration: The sensor supports a wide range of cable lengths (typically 5m or 9m total system length). This flexibility allows engineers to mount the Proximitor in a safe, accessible location away from the extreme heat of the machine housing.

• Tool-Free Secure Locking: Bently Nevada’s proprietary ClickLoc™ connectors snap into place, creating a moisture-resistant and vibration-proof seal. This prevents accidental disconnections that lead to false machine trips or data loss.

FAQs

1. Does the 288055-02 require a specific mounting orientation?

No. You can mount the Proximitor assembly in any orientation. However, we recommend using the standard DIN rail mount or a specialized Proximitor housing to protect the terminals from environmental contamination.

2. Can I use this sensor with older 7200 series probes?

The 3300 XL series provides backward compatibility in many cases, but you must verify the total system length and target material (typically 4140 steel). For optimal accuracy, always pair the 288055-02 with 3300 XL series probes.

3. What is the significance of the -02 suffix in the part number?

The -02 suffix designates the specific assembly configuration, typically including the mounting hardware or a specific calibration for 5-meter or 9-meter systems. Check your system manual to ensure it matches your existing transducer loop.

4. Is the unit factory calibrated?

Yes. Every 288055-02 leaves the factory calibrated to standard 4140 steel targets. If your shaft utilizes a different alloy, you may need to apply a scale factor within your monitoring software.
