30944-01 Bently Nevada 3300 XL Transducer Interface

Product Overview

The Bently Nevada 128275-01F and 130944-01 function as high-performance signal conditioning units within the 3300 XL Proximity Transducer System. These Proximitor® sensors receive raw eddy current signals from proximity probes and convert them into linear voltage outputs. This conversion allows monitoring systems to track critical shaft vibration and axial position in real-time. We supply these modules as 100% Brand New and Original, ensuring your turbines, compressors, and pumps operate under the highest machinery protection standards.

Technical Specifications

Engineering Advantages

• Optimized Signal Linearity: These Proximitor sensors deliver a stable voltage-to-displacement ratio (standardized at 200 mV/mil). This precision allows your 3500 or 1900/65A monitoring system to identify subtle mechanical shifts before they escalate into bearing failure or rotor contact.

• Superior EMI/RFI Immunity: The 128275-01F and 130944-01 feature advanced internal shielding that rejects electromagnetic interference. This design prevents electrical "noise" from high-voltage motors or nearby radio frequency sources from corrupting your critical vibration data.

• Vibration-Proof ClickLoc™ Interconnects: The assembly utilizes gold-plated ClickLoc™ connectors. These provide a secure, tactile locking mechanism that prevents accidental disconnection even when the sensor assembly mounts directly to a high-vibration machinery frame.

• Streamlined Rack Deployment: The slim form factor (24.2 cm height) ensures perfect alignment within Bently Nevada 3500 system racks or local junction boxes. Its standardized mounting footprint simplifies hardware expansion, allowing for high-density sensor arrays in limited cabinet space.

FAQs

1. Are the 128275-01F and 130944-01 interchangeable?

While both belong to the 3300 XL Proximitor family, you must match the specific part number to your original system configuration. These variants often differ in their specific internal calibration lengths (e.g., 5-meter vs. 9-meter systems) or agency approval certifications.

2. Can I use these sensors with legacy 7200 series probes?

The 3300 XL series significantly improves upon legacy systems, but we strictly recommend using 3300 XL probes and extension cables. Mixing components from different series degrades the 1% linearity tolerance required for API 670 machinery protection.

3. Do these modules require field calibration after installation?

No, these sensors arrive factory-calibrated. However, we recommend performing a loop verification using a Bently Nevada TK-3 calibrator. This ensures that the entire transducer chain (probe, cable, and proximitor) reports the correct voltage-to-gap ratio.

4. How do I protect the ClickLoc™ connectors from corrosive environments?

While the connectors are gold-plated to resist oxidation, we recommend installing the 128275-01F / 130944-01 within a NEMA 4X or IP66-rated enclosure for offshore or chemical plant applications to prevent moisture ingress and chemical degradation.
