        General

        • Manufacturer GE / Bently Nevada
        • Model 102046-50
        • Condition New Original ready stock
        • Product Family 102047-50,102046-20
        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Key Displacement Measurement: Primarily used for monitoring radial vibration and axial displacement in high-speed rotating machinery (such as steam turbines, centrifugal compressors, pumps, and generators).
        • Speed ​​and Phase Reference: Used as a Keyphasor® probe, it provides accurate speed signals and phase reference points, which are crucial for analyzing mechanical imbalances and shaft trajectories.
        • Industry Coverage: Widely used in industries with extremely high requirements for continuous equipment operation, such as oil and gas, power (nuclear/thermal), chemical, steel, and mining.
        • Hardware Evolution: Bently Nevada periodically optimizes hardware materials (such as the PPS material at the probe tip or the ClickLoc™ connector design), but these are iterations of the physical design, not firmware updates.
        • System-Level Updates: If the probe is connected to a 3500 monitoring frame or Orbit 60 system, relevant firmware updates typically occur at the digital interface level of the backend monitoring module (such as the TDI data acquisition module) or the proximitor.
        • Compatibility: The 3300 XL probe is backward compatible with older 3300 systems; upgrades typically only require replacing the proximitor hardware for better performance.
        • Physical Configuration (Installation Gap): During installation, the distance (gap) between the probe and the rotating shaft needs to be adjusted. The standard static bias voltage is typically set at -10.0 Vdc (corresponding to approximately a 1.27 mm gap) to ensure the signal is centered within a linear range of 200 mV/mil.
        • Software Configuration:In the Bently Nevada 3500 frame software, the sensor type for the corresponding channel needs to be configured as "3300 XL 8mm Proximity System".
        • Sensitivity setting: Default is 200 mV/mil (7.87 V/mm). Unless using non-standard target materials (such as materials other than 4140 steel), there is no need to modify the scale factor.
        Description
        The 102046-50 Proximitor Sensor represents a sophisticated advancement in eddy current technology, specifically engineered for the 3300 series monitoring environment. By maintaining a linear output across its specified range, this module allows operators to detect minute changes in shaft position or vibration levels. 

        Designed for seamless integration, the 102046-50 provides a standardized 200 mV/mil (7.87 V/mm) output when used with compatible 5mm or 8mm probes. This consistency is vital for maintenance teams who require interchangeable parts that do not necessitate constant recalibration of the entire monitoring rack. 

        Durability is a hallmark of the 102046-50 architecture, featuring a housing that resists environmental contaminants and chemical exposure. Its internal circuitry is encapsulated to withstand the high-vibration environments typical of turbine decks and compressor sheds. 

        Field technicians value the 102046-50 for its straightforward DIN rail mounting and clear terminal labeling, which significantly reduces installation time and potential wiring errors. Whether monitoring axial thrust, radial vibration, or shaft speed, the 102046-50 delivers the stable performance necessary for long-term trend analysis.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Can the 102046-50 be used in food processing areas where high-pressure wash-down is routine?
        Yes, absolutely. The 102046-50 features an IP67 protection rating when properly mated, meaning it is dust-tight and protected against temporary immersion in water. This makes it highly resistant to the high-pressure wash-down cycles common in food processing, solving the problem of water ingress damaging standard connectors.
        What is the advantage of the gold-plated contacts on the 102046-50 for a precision measurement application?
        The gold-plated contacts on the 102046-50 provide extremely low and stable contact resistance. This prevents signal loss and distortion, which is critical for precision sensors measuring small variations. It solves the pain point of inaccurate readings caused by corrosion or poor conductivity in standard connectors over time.
        Is the 102046-50 compatible with standard M12 panel mount receptacles used on industrial control cabinets?
        Yes, the 102046-50 features a standard M12 x 1.0 threaded coupling nut designed for universal compatibility. It will securely mate with any standard A-coded M12 panel mount receptacle, solving the common issue of connector incompatibility between different cabinet components and field cables.
        How does the temperature range of the 102046-50 benefit outdoor installation in cold climates?
        With an operating range down to -25°C, the 102046-50 is specifically designed to remain flexible and maintain its sealing integrity in freezing conditions. Standard connectors can become brittle and crack at low temperatures, but the 102046-50 solves this by retaining its mechanical strength, ensuring reliable operation even in sub-zero outdoor environments.
