Product Overview
The BENTLY 22810-01-05-50-02 is a high-performance proximity transducer system designed for precision measurement of machinery vibrations and axial positions in demanding industrial environments. As part of Bently Nevada’s legacy 3300 Series, this non-contacting sensor provides critical input for turbine, generator, and compressor protection systems, enabling early detection of mechanical faults such as rotor imbalance, misalignment, and bearing wear. Its robust design and wide temperature tolerance make it a staple in power generation, oil refining, and heavy manufacturing sectors where equipment reliability is paramount.
The system comprises a probe, extension cable, and proximity driver, forming a complete solution for monitoring shaft displacement and vibration. The BENTLY 22810-01-05-50-02 supports dual-channel redundancy, allowing simultaneous measurement from two probes for enhanced fault tolerance. Its 4–20 mA output interfaces seamlessly with Bently Nevada’s 3500 monitoring system or third-party PLCs, providing actionable data for alarm thresholds and predictive maintenance programs.
What sets this transducer apart is its ability to operate in extreme conditions, including high-vibration zones and temperatures up to 175°C. For industries relying on legacy machinery, the BENTLY 22810-01-05-50-02 offers drop-in compatibility with existing 3300 Series infrastructure, minimizing retrofit costs while upgrading measurement accuracy.

Key Features and Benefits
The BENTLY 22810-01-05-50-02 excels in high-temperature environments, withstanding 175°C continuous operation without signal degradation. Its titanium probe housing resists corrosion from process fluids, making it ideal for steam turbine casings or offshore drilling platforms.
Diagnostic capabilities include onboard self-test routines that verify probe-to-target spacing and cable integrity. Operators can monitor these metrics via Bently Nevada’s ADAPT.windows™ software, identifying degraded sensors before false trips occur. The system’s 10 kHz bandwidth captures transient vibrations invisible to slower sensors, such as those from gear meshing or blade pass frequencies.
For hazardous areas, the transducer’s ATEX/IECEx certification ensures safe operation in Zone 1/21 environments, while its IP68 rating permits temporary submersion during equipment washdowns. Dual-channel redundancy eliminates single points of failure, critical for applications like nuclear reactor coolant pumps or LNG liquefaction trains.
Interoperability is enhanced by compatibility with both legacy 3300 Series and modern 3500 monitoring systems, allowing phased upgrades without system-wide downtime. The transducer’s 24-bit resolution provides sub-micron measurement accuracy, essential for balancing precision machinery like aeroderivative gas turbines.
Application Scenarios
In nuclear power plants, the BENTLY 22810-01-05-50-02 monitors reactor coolant pump bearings, detecting sub-surface cracks before they compromise containment integrity. Its 175°C rating ensures reliability in primary loop environments where conventional sensors would fail.
Oil refineries deploy this transducer on hydrocracker compressors, where it tracks rotor axial movement during catalyst regeneration cycles. By correlating displacement data with process pressure, engineers optimize anti-surge control strategies to extend compressor life.
The system’s IP68 rating makes it suitable for hydroelectric generators, where it operates submerged in lubricating oil to measure thrust bearing wear. Here, it provides early warning of bearing degradation, preventing costly stator or rotor damage.
In steel mills, the BENTLY 22810-01-05-50-02 safeguards rolling mill drives by monitoring backlash in planetary gearboxes. Its 10 kHz sampling rate captures gear tooth impacts, enabling predictive maintenance before catastrophic failures disrupt production.

Installation and Maintenance
Prior to installing the BENTLY 22810-01-05-50-02, ensure the mounting surface is free of magnetic debris and aligned to achieve 0.25–0.38 mm probe-to-target clearance. Use Bently Nevada’s TK-81 calibration kit to verify linearity across the measurement range, adjusting the proximity driver’s gain if deviations exceed ±0.5%.
For maintenance, perform quarterly insulation resistance tests between the probe and casing using a 500 VDC megger, ensuring readings exceed 100 MΩ. Validate cable integrity annually by injecting 1 Vpk sine waves and checking for signal attenuation beyond 3 dB at 10 kHz. Replace the transducer if self-test errors persist, as this may indicate internal coil degradation. When upgrading firmware, always disconnect power to avoid parameter corruption.
