New Bently Nevada 149758-01 Proximitor Assembly Original

Product Overview

The Bently Nevada 149758-01 serves as the essential signal conditioning unit for the 3300 XL Proximity Transducer System. This Proximitor® Sensor converts the raw eddy current signals from a proximity probe into a precise DC voltage output. This output corresponds directly to the physical displacement or vibration of a rotating shaft. We supply this module as 100% Brand New and Original, ensuring your critical turbomachinery remains protected by the highest standard in industrial monitoring technology.

Technical Specifications

Engineering Advantages

• Superior Signal Linearity: The 149758-01 provides a stable 7.87 V/mm (200 mV/mil) output. This consistency allows for pinpoint accuracy in detecting axial thrust changes or radial vibration levels, critical for early fault detection in high-speed compressors and pumps.

• Immunity to Radio Frequency Interference (RFI): Modern industrial environments generate significant electrical noise. The shielded circuitry within the 3300 XL Proximitor prevents RFI from corrupting your data, ensuring that the monitoring rack receives only clean, accurate vibration signals.

• Secure ClickLoc™ Interconnects: This assembly utilizes gold-plated ClickLoc™ connectors. The locking mechanism prevents the interconnect cable from shaking loose under high-vibration conditions, which eliminates the primary cause of intermittent signals and false alarms.

• Streamlined Integration: The compact footprint simplifies installation within local junction boxes or centralized 3500 series racks. Its non-contacting measurement principle means the sensor never touches the machinery, preventing wear and allowing for continuous, 24/7 condition monitoring.

FAQs

1. Is the 149758-01 compatible with 5-meter and 9-meter systems?

The 149758-01 is specifically tuned for a specific system length (typically 9.0 meters total). You must match the Proximitor length option with your extension cable and probe lead length to maintain the calibrated 200 mV/mil output.

2. Can I use this sensor with non-Bently Nevada probes?

No. Bently Nevada Proximitor sensors utilize proprietary eddy current frequencies tuned to the specific metallurgy and impedance of 3300 XL probes. Using generic probes will result in inaccurate data and potential machinery protection failure.

3. What is the recommended mounting procedure for the 149758-01?

We recommend mounting the Proximitor on a 35 mm DIN rail inside a weatherproof enclosure. Ensure the enclosure provides adequate grounding to the machine casing to minimize ground loops and signal interference.

4. How do I verify the calibration of a new 149758-01 unit?

Upon installation, use a TK-3 Proximity System Calibrator to simulate shaft movement. Verify that the output voltage changes by 200 mV for every 1 mil (0.025 mm) of displacement to ensure the entire transducer loop is functioning correctly.
