Bently Nevada 330780-51-05 3300 XL Proximitor Sensor

The Bently Nevada 330780-51-05 is a high-performance Proximitor® sensor from the 3300 XL series, specifically engineered to function as the signal conditioner and amplifier within a complete 11 mm proximity transducer system . As the critical link between the 11 mm eddy current proximity probe and your monitoring system (such as the 3500/42M), this sensor powers the probe, processes the raw gap voltage signal, and outputs a precise, high-level signal proportional to the distance between the probe tip and the target shaft .

 

Designed for non-contacting vibration and displacement measurements on fluid film bearing machines, this module is an ideal solution for modernizing legacy monitoring infrastructure, particularly as a seamless upgrade for outdated 7200-series transducer systems . Its advanced design ensures superior reliability and is a cornerstone component for building robust machinery protection systems in the most demanding industrial environments .

 

The specific model 330780-51-05 is configured as a 5.0-meter total system length unit with a DIN-rail mount and multiple international agency approvals.

    Bently Nevada 330780-51-05 3300 XL 11 mm Proximitor Sensor

    High-Performance Signal Conditioner for 11 mm Proximity Transducer Systems 

    New and Original

    Key Features & Benefits

    • Direct Legacy Upgrade Path: Engineered to fully replace 7200-series 11 mm and 14 mm transducer systems, providing a complete, hassle-free upgrade path to the advanced 3300 XL platform .

    • Long Linear Range for Superior Monitoring: Features a 4.0 mm (160 mils) linear measurement range, a significant advantage over standard 8 mm probes for applications requiring extended reach, such as axial thrust position monitoring .

    • High Fidelity Signal Output: Delivers a standard scale factor of 3.94 V/mm (100 mV/mil) , enabling accurate measurement of both dynamic vibration and static shaft position .

    • Enhanced Immunity to Electrical Noise: Improved RFI/EMI immunity allows the sensor to meet stringent European CE mark approvals without requiring special shielded conduit or metallic housings, reducing installation costs and complexity .

    • Tool-Free Field Wiring: Equipped with SpringLoc™ terminal strips that require no special installation tools, facilitating faster, more robust, and secure field wiring connections compared to traditional screw-type terminals .

    • Flexible Installation Options: Its thin, compact design supports both high-density DIN-rail mounting and traditional panel mount configurations .

    • Wide Operating Temperature Range: Engineered for harsh industrial environments with an operating temperature range of -52°C to +100°C (-62°F to +212°F) .

    • Comprehensive Safety Approvals: Holds CE, ATEX, and IECEx certifications, making it suitable for use in potentially hazardous areas requiring stringent safety compliance .

    Part Number Breakdown

    The part number 330780-51-05 provides specific configuration details :

     
     
    Suffix Code Meaning
    330780 - Base model for 3300 XL 11 mm Proximitor Sensor 
    -51 - 5 = 5.0-meter total system length; 1 = DIN-rail mount 
    -05 - Multiple international agency approvals (e.g., CE, ATEX) 

    Complete System Requirement

    The Proximitor sensor is one-third of a complete transducer system. For optimal performance and proper calibration, it must be used with a matching Bently Nevada 11 mm probe (e.g., 33070X series) and extension cable (e.g., 330730 series) . Mixing probe diameters (e.g., an 8 mm probe with an 11 mm Proximitor) will corrupt calibration and alter the voltage scale factor, leading to inaccurate measurements .

    Applications

    This sensor is the ideal electronic cornerstone for critical machinery monitoring and protection across various industries:

     
     
    Industry Application
    Power Generation Shaft vibration and axial thrust position monitoring on large steam and gas turbines, generators, and critical pumps .
    Oil & Gas Condition monitoring of high-speed machinery such as centrifugal compressors, turbo-expanders, and pipeline pumps .
    Heavy Industrial Rotating equipment monitoring in steel mills, paper plants, and other heavy manufacturing facilities .
    Petrochemical Upgrading legacy monitoring systems in refineries and offshore platforms where hazardous area compliance is required .
