        • Large Stroke Axial Displacement Control: Due to the larger measuring range of the 11 mm probe compared to 8 mm (approximately 4 mm), it is commonly used to monitor severe wear of thrust bearings, triggering DCS alarms or trip protection.
        • Differential Expansion Monitoring: Controls the difference in thermal expansion between the rotor and casing during turbine startup or shutdown to prevent collisions.
        • Eccentricity Monitoring: Monitors the degree of bending of the main shaft during low-speed rotation (turning gear) to control startup timing.
        • Reciprocating Compressor Connecting Rod Settlement: Monitors the wear condition of the reciprocating compressor connecting rod, providing preventative maintenance data.
        • Large steam turbine units: Measurement of differential pressure in high-pressure and intermediate-pressure cylinders; this is its most classic application.
        • Gas turbines: Monitoring the axial position of the rotor under high-temperature, high-speed conditions.
        • Reciprocating compressors: Measuring piston rod drop and monitoring wear of the bearing rings.
        • Large fans and pumps: Replacing smaller 8 mm probes in sliding bearing equipment with a large axial movement range.
        • ClickLoc™ Coaxial Connector: The probe tip has a gold-plated connector with an anti-loosening design, allowing direct connection to an extension cable or preamplifier.
        • Three-wire signal transmission: Powered by -24V DC, with signal (SIG) and common (COM) terminals output via a preamplifier, typically using a shielded three-core cable.
        • Connection to monitoring frame: Connects to a Bently Nevada 3500/22M (transient data interface) or 3500/42M (displacement/vibration monitoring module).
        • Insulated mounting: The probe housing is threaded onto the machine bearing housing; insulating bushings are typically used at the connection to isolate industrial noise interference.

        Description
        The Bently Nevada 330703-000-050-50-02-00 3300 XL 11 mm Probe is a high-precision 11 mm eddy-current proximity sensor designed for industrial monitoring of fluid-film bearing machines. Constructed for durability and long-term reliability, the probe operates with a DC resistance of 7.2 ± 0.8 ohms and is capable of handling extreme temperatures ranging from -52°C to +177°C (-62°F to +351°F). Its robust design, featuring a miniature coaxial ClickLoc connector with standard cable, ensures secure signal transmission in demanding environments.

        With a minimum unthreaded length of 0 mm and an overall case length option of 50 mm, the 330703-000-050-50-02-00 probe allows for flexible installation in tight spaces. Its total cable length of 5.0 meters (16.4 feet) accommodates varied mounting configurations without compromising measurement accuracy. The probe is designed without armor for straightforward integration into the 3300 XL 11 mm Proximity Transducer System.

        The 330703-000-050-50-02-00 probe is part of the 3300 XL 11 mm system, which includes the 11 mm probe, corresponding extension cable, and 11 mm Proximitor Sensor. This system delivers a 3.94 V/mm (100 mV/mil) output for non-contacting vibration and displacement measurements, offering a longer linear range than standard 8 mm 3300 XL probes. This extended range is particularly advantageous for axial (thrust) position, ramp differential expansion on steam turbines, and rod position monitoring on reciprocating compressors.

        The Bently Nevada 330703-000-050-50-02-00 probe also supports tachometer and zero-speed measurements, as well as phase reference (Keyphasor) signals. It is designed as a direct replacement for 7200-series 11 mm and 14 mm transducer systems, allowing users to upgrade to the 3300 XL 11 mm system while achieving improved accuracy and linearity. When upgrading from the 7200 series, all components and configuration software must be updated to maintain compatibility with 3300 XL 11 mm components.
