        Features:

        • Extended linear measurement range for demanding displacement applications.
        • Armored FluidLoc cable with protected locking connector construction.
        • Stainless-steel body, PPS tip, and high-strength cable attachment.
        Reliable shaft-position monitoring is essential on turbines, compressors, and machines using fluid-film bearings. Bently Nevada 330702-00-25-10-11-05 provides the sensing element required for continuous non-contact measurement when movement must be observed without physical contact with the shaft. The extended range supports applications involving larger axial or mechanical movement. A 100 mV/mil output allows the probe system to produce a standardized signal for compatible monitoring equipment. Industrial operators can apply the probe to protection, condition monitoring, and diagnostic measurement functions.

        Installation conditions around rotating machinery can expose probe cables to oil, moisture, vibration, and mechanical stress. Bently Nevada 330702-00-25-10-11-05 addresses such conditions through armor, FluidLoc construction, and a protected ClickLoc connection. Stainless-steel case material supports mechanical durability, while the PPS tip provides the required sensing-end construction. Safety-wire holes in the locknut help secure the probe after adjustment. Such features are valuable in steam-turbine, compressor, and other critical-machinery installations.

        Modernization projects can use Bently Nevada 330702-00-25-10-11-05 as part of a complete transition from older 7200-series 11 mm or 14 mm systems. Successful migration requires matched 3300 XL 11 mm probes, extension cables, Proximitor Sensors, and compatible monitor configuration. The one-meter cable length suits installations where the sensing point and extension-cable connection are positioned relatively close together. Multiple approvals support use across different regulated industrial environments. Proper component matching helps maintain the specified linear range, output scale, and measurement performance.

        The 330702-00-25-10-11-05 Bently Nevada 3300 XL 11 mm Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Steam Turbine Units: Used for monitoring the axial displacement of the main shaft of large steam turbines, accurately capturing micron-level axial movement under high-speed rotation.
        • Gas ​​Turbines: Used for radial vibration measurement of bearing clearances, providing real-time monitoring of the dynamic balance of the turbine shaft system in high-temperature and high-pressure environments.
        • Compressor Units: Used for large bearing bush wear monitoring in centrifugal or reciprocating compressors, providing early warning of severe mechanical jamming and damage.
        • Large Water Pumps: Used for measuring the bearing clearance of large circulating water pumps in power plants and water conservancy projects, preventing rotor rubbing and bearing failure accidents caused by bearing overload.
        • Gearbox Shafts: Used for differential thermal expansion monitoring of the input and output shafts of speed-increasing gearboxes, ensuring optimal mechanical meshing in complex transmission systems.
        • Insulation and Moisture Resistance: The probe tip is encapsulated with extruded fluoropolymer, providing extremely high resistance to chemical corrosion and liquid penetration.
        • Physical Shock Resistance: The internal circuitry is encapsulated with high-strength epoxy resin, resisting mechanical fatigue and structural damage caused by high-frequency, severe vibrations.
        • Signal Shielding: The armored cable layer provides 100% protection against radio frequency interference (RFI) and electromagnetic interference (EMI), ensuring signal integrity even in harsh electromagnetic environments.
        • Extreme Temperature Resistance: Core components support operation in a wide temperature range, providing stable thermal protection for field testing in conditions ranging from sub-zero temperatures to high-temperature steam.
        • Error Prevention: Features self-diagnostic fault protection (OK circuit) when used with the preamplifier. It immediately sends an alarm to the monitor when the sensor experiences a disconnection or short circuit.
        • Standard Output: Strictly adheres to the unified linearity curve of the Bentley 3300 XL series, enabling seamless integration with other standard 3300 XL 11mm preamplifiers.
        • Module Compatibility: Supports 3.9 V/mm (100 mV/mil) sensitivity system standards, allowing direct integration into mainstream mechanical protection systems such as the 3500/22M.
        • Cable Compatibility: The connector uses a special coaxial gold connector, allowing for arbitrary combination and extension of system cables with the same electrical properties without affecting measurement accuracy.
        • Physical Replacement: The thread specifications and dimensions adopt industry-standard industrial design, allowing for 1:1 in-situ replacement of older, outdated 11mm probes.
        • Seamless System: Data output is fully compatible with mainstream industrial control networks, facilitating cross-platform data sharing with PLCs, DCSs, or remote asset management software.
        Description
        With an 11 mm probe tip and extended linear measurement range, Bently Nevada 330702-00-25-10-11-05 supports machinery applications where a standard 8 mm transducer system may not provide sufficient range. The complete 3300 XL 11 mm Proximity Transducer System consists of a 3300 XL 11 mm probe, a matching extension cable, and a 3300 XL 11 mm Proximitor Sensor. System output is 3.94 V/mm, equivalent to 100 mV/mil, for non-contacting vibration and displacement measurement on fluid-film bearing machines. Common uses include axial thrust position, steam-turbine ramp differential expansion, reciprocating-compressor rod position or rod drop, tachometer and zero-speed measurement, and Keyphasor phase-reference signals.

        Mechanical construction for Bently Nevada 330702-00-25-10-11-05 includes a 1/2-20 UNF mounting thread, an armored cable configuration, zero-inch unthreaded length, and a 2.5-inch overall case length. Total probe length is 1.0 meter, or 3.3 feet, and probe DC resistance is 5.9 ± 0.5 ohms. The probe tip is manufactured from polyphenylene sulfide, while the probe case uses AISI 304 stainless steel. A locknut with pre-drilled safety-wire holes is supplied as a standard feature for secure mounting.

        Signal connection on Bently Nevada 330702-00-25-10-11-05 uses a miniature coaxial ClickLoc connector with a connector protector and FluidLoc cable. Gold-plated brass ClickLoc connectors lock into position to reduce the risk of loosened connections. TipLoc molding creates a strong bond between the probe tip and probe body, while CableLoc construction secures the cable to the probe tip with a rated pull strength of 330 N, or 75 lb. FluidLoc construction helps prevent oil and other liquids from escaping through the cable interior, and the connector protector increases protection in humid or moist installations.

        The cable fitted to Bently Nevada 330702-00-25-10-11-05 is a 75-ohm triaxial probe cable with fluoroethylene propylene insulation. The 3300 XL 11 mm family is available in total probe lengths of 1, 5, or 9 meters and can be supplied with armored or unarmored 1/2-20, 5/8-18, M14 x 1.5, and M16 x 1.5 thread configurations. Reverse-mount versions use either 3/8-24 or M10 x 1 threads. Operating and storage temperatures range from -52°C to +177°C, and the selected configuration carries multiple agency approvals.

        As a replacement platform, Bently Nevada 330702-00-25-10-11-05 belongs to the 3300 XL 11 mm system developed to replace 7200-series 11 mm and 14 mm transducer systems. A complete upgrade requires replacement of every probe-system component with compatible 3300 XL 11 mm components. The associated monitoring system must also be updated. A 3500 Monitoring System requires a configuration-software version that lists the 3300 XL 11 mm Proximity Transducer System as a compatible option.
