Product Overview
The Bently Nevada 128276-01E and 131151-01 operate 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 data 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.

Engineering Advantages
-
Optimized Signal Linearity: These Proximitor sensors deliver a stable voltage-to-displacement ratio (typically 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 128276-01E and 131151-01 feature advanced 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.
-
Future-Proof Expansion Design: The compact "Half Future Expansion" footprint (12 cm x 3 cm) allows for high-density sensor mounting in confined junction boxes or local control panels. This minimizes space requirements while maintaining full access for troubleshooting and maintenance.
FAQs
1. Are the 128276-01E and 131151-01 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 mounting hardware or internal calibration lengths (e.g., 5-meter vs. 9-meter systems).
2. Can I use these sensors with legacy 7200 series probes?
The 3300 XL series is designed to replace and improve upon legacy systems, but we strictly recommend using 3300 XL probes and extension cables. Mixing components from different series can degrade 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 128276-01E / 131151-01 within a NEMA 4X or IP66-rated enclosure for offshore or chemical plant applications to prevent moisture ingress.
