        Features:

        • Interface Between the 3300 XL 50 mm Probe and 3300 XL 50 mm Proximitor Sensor
        • Combines Capability of Signal Transmission with High-Temperature Environmental Protection
        • Operates in Conjunction with the 3300 XL 50 mm Transducer System and Standard Bently Nevada Monitoring Equipment
        The 330877-040-36-00 operates as the 3300 XL 50 mm Extension Cable in a 3300 XL 50 mm Transducer System, providing reliable signal transmission between the 50 mm probe and the 3300 XL 50 mm Proximitor Sensor. It continuously maintains signal integrity across its 4.0 meters (13.1 feet) cable length and utilizes FluidLoc cable armor to protect against moisture ingress and harsh environmental conditions in steam turbine DE applications. Seamless connectivity is standard with the 330877-040-36-00, with its high-temperature ClickLoc connectors ensuring secure, contamination-free connections even in extreme thermal environments. The 330877-040-36-00 has made improvements in several areas over previous extension cable designs in addition to incorporating FluidLoc cable capability within the 3300 XL 50 mm system.

        The 330877-040-36-00 provides essential signal transmission functions common to the entire transducer system, and is a critical component of the differential expansion (DE) or rotor expansion (RX) monitoring path, directly affecting the accurate measurement of growth rate differences between turbine rotors and machine stators in large steam turbine generators. One 330877-040-36-00 extension cable is required per probe installation to connect the 50 mm probe to the Proximitor Sensor. The 330877-040-36-00 occupies a flexible position in the system layout and is always routed between the probe and the Proximitor Sensor, with its removable collar feature facilitating cable routing through tight clearances.

        For demanding steam turbine DE applications requiring extended cable runs, the 3300 XL 50 mm System requires the 330877-040-36-00 extension cable to bridge the physical gap between the probe mounted near the differential expansion collar and the Proximitor Sensor located in the monitoring cabinet. In addition to standard signal transmission, the FluidLoc cable configuration also performs environmental sealing. The 330877-040-36-00 cable design executes moisture blocking using the FluidLoc cable armor and dual sealing system specified in the cable options. Using this method, the extension cable continually prevents moisture from penetrating the probe tip through both front and rear seals. If the system detects harsh environmental conditions including high humidity or temperature fluctuations up to 200°C (392°F) continuous or 250°C (482°F) intermittent, the 330877-040-36-00 maintains signal accuracy and connector integrity, supported by the included connector protectors and disposable installation tool that ensure the ClickLoc connections remain free of contamination throughout the cable service life.

        The 330877-040-36-00 Bently Nevada 3300 XL 50 mm Extension Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Environmental Sealing: The FluidLoc design prevents moisture and process fluids from entering the probe tip or leaking out of the machine.
        • Connector Protection: Features gold-plated ClickLoc connectors that provide a secure, vibration-resistant connection without special tools.
        • Signal Integrity: High resistance to Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) ensures accurate readings even near high-frequency radio signals.
        • Differential Expansion (DE): Measuring the difference in growth rates between a steam turbine rotor and its stator.
        • Rotor Expansion (RX): Tracking the physical expansion of the rotor in large generators.
        • Large Steam Turbines: Ideal for any application requiring the system’s maximum linear range of 27.9 mm (1100 mils).
        • System Integrity: To maintain accuracy, all components (probe, cable, and sensor) must be from the 3300 XL 50 mm series; mismatching with other sizes will result in incorrect data.
        • Backward Compatibility: This system is a robust replacement for older 7200 series 50 mm and 130713 DE systems.
        • Monitoring Systems: It provides a 0.394 V/mm (10 mV/mil) output, allowing it to interface with existing monitors without reconfiguring the hardware.

        Description
        The 3300 XL 50 mm Extension Cable, model 330877-040-36-00, is a critical component of the 3300 XL 50 mm Transducer System, specifically designed for demanding industrial measurement applications. This extension cable features a length of 4.0 meters (13.1 feet) and is equipped with FluidLoc cable armor, providing robust protection against harsh environmental conditions. The 330877-040-36-00 incorporates special high-temperature ClickLoc connectors as standard features, ensuring secure and reliable connections between the probe and the Proximitor Sensor. Each 330877-040-36-00 comes complete with connector protectors and a disposable connector protector installation tool, which are essential for maintaining contamination-free connections during installation and operation.

        The 330877-040-36-00 extension cable is specifically engineered to complement the 3300 XL 50 mm probe in measuring differential expansion (DE) or rotor expansion (RX) of large steam turbine generators. This 330877-040-36-00 cable enables the system to accurately capture the difference in growth rates between the turbine rotor and the machine stator (casing), a critical parameter for preventing catastrophic failures in power generation equipment. The FluidLoc cable option on the 330877-040-36-00 provides superior moisture resistance, making it ideal for steam turbine environments where high humidity and temperature fluctuations are common.

        This 330877-040-36-00 extension cable is designed to operate reliably in extreme conditions, supporting continuous operation at temperatures up to 200°C (392°F) and withstanding intermittent temperatures as high as 250°C (482°F). The 330877-040-36-00 seamlessly integrates with the 3300 XL 50 mm probe's front and rear sealing system, ensuring that moisture cannot penetrate the probe tip even in the most challenging steam turbine DE environments. When paired with the probe, the 330877-040-36-00 enables flexible mounting configurations, including setups where two transducers observe the same side of a collar for redundant measurements, or complementary installations on opposite sides of a collar to effectively double the measurable DE range when 28 mm to 56 mm of total range is required.
