        Features:

        • 330704-000-080-50-12-00 combines M14x1.5 metric thread with full armor and FluidLoc oil-blocking cable technology.
        • Zero unthreaded length paired with 80mm case satisfies 26mm differential rule for metric mounting configurations.
        • 11mm tip delivers 4.0mm linear range and 3.94 V/mm output for axial position and differential expansion measurements.
        The 330704-000-080-50-12-00 offers comprehensive protection for demanding industrial applications. The M14 x 1.5 metric threading suits installations outside North America where metric standards prevail. The flexible AISI 302 stainless steel armor surrounds the cable, providing exceptional resistance to crushing, cutting, and impact damage in harsh environments such as turbine decks and compressor skids. Complementing the armor, FluidLoc cable technology seals the cable interior, preventing oil migration through conductor bundles and eliminating leakage at termination points.

        The 330704-000-080-50-12-00 features an 11 mm tip diameter that delivers significantly longer linear range compared to standard 8 mm probes. This system provides a 4.0 mm (160 mil) linear range with output of 3.94 V/mm (100 mV/mil), operating from approximately 0.5 mm to 4.5 mm gap (-1 to -17 Vdc). An extended DSL range reaches 5.0 mm (200 mils) at -19 Vdc. This extended range capability makes the 330704-000-080-50-12-00 ideal for axial (thrust) position monitoring where rotor movement can exceed 8 mm probe limits.

        The 330704-000-080-50-12-00 has a total length of 5.0 meters (50), designed exclusively for use with 5-meter Proximitor sensors (330780-50 panel mount, 330780-51 DIN mount, or 330780-52 no mounting hardware). The 5-meter configuration balances installation flexibility with signal integrity for most industrial applications. The standard temperature rating is 177°C (350°F), suitable for most turbine and compressor environments. For higher temperature applications requiring hazardous area approvals, other configurations with option 05 (Multiple Approvals) or extended temperature range versions should be selected.

        The 330704-000-080-50-12-00 Bently Nevada Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Thrust (Axial Position) Monitoring: Deployed on the thrust collar of utility-scale steam and gas turbines to monitor axial rotor float under high thermal load shifts.
        • Ramp Differential Expansion (DE): Positioned facing a ramp or collar on the shaft to measure the relative growth differential between the turbine rotor and its stator casing during startup and shutdown cycles.
        • Large Journal Bearings: Monitors radial vibration and shaft centerlines in massive process compressors and fans that exhibit large fluid-film bearing clearances or heavy oil-whirl amplitudes.
        • Extreme Thermal Tolerance: The probe head and integral cable are fully rated to operate reliably within a -51°C to +177°C (-60°F to +350°F) temperature spectrum.
        • Chemical & Pressure Sealing: The probe tip utilizes Bently's patented TipLoc™ molding technology, chemically bonding the PPS (Polyphenylene Sulfide) head to the stainless steel body. This provides complete immunity to hot synthetic and mineral turbine oils.
        • Premium Mechanical Strength: Incorporates CableLoc™ structural design, allowing the cable-to-probe junction to withstand up to 330 Newtons (75 lb) of continuous pulling tension without snapping.
        • Mechanical Centering (Physical Gapping): During mechanical commissioning, the probe is threaded into its bracket until its tip sits at the midpoint of its linear range—exactly 2.0 mm (80 mils) away from the target metal surface.
        • Electrical Gapping Verification: When properly gapped at rest, verify that the continuous DC voltage output measured across the Proximitor OUT and COM terminals reads exactly -10.0 Vdc.
        • "Not OK" Circuit Self-Diagnostics: The companion 3500 monitor continuously scans the electrical loop. If a wire snaps, a connector becomes flooded with oil, or the probe tip is struck by debris, the DC bias voltage instantly faults outside its linear limits.
        Description
        he 330704-000-080-50-12-00 is a metric-threaded 3300 XL 11 mm proximity probe with full armor protection. This configuration specifies M14 x 1.5 threads, zero unthreaded length (000), and an 80 mm overall case length (080). The 330704-000-080-50-12-00 delivers 5.0 meters total length (50) and features FluidLoc cable technology with standard agency approval (00). measurements.

        FluidLoc cable on the 330704-000-080-50-12-00 prevents oil and other liquids from leaking through the cable interior. This sealing capability is essential for steam turbine differential expansion monitoring and reciprocating compressor rod position measurements. The 330704-000-080-50-12-00 utilizes TiLoc molding for tip-to-body bonding and CableLoc design providing 330 N (75 lbf) pull strength. 

        With zero unthreaded length and 80 mm case, the 330704-000-080-50-12-00 satisfies the metric requirement that unthreaded length be at least 26 mm less than case length (0 mm ≤ 80 mm - 26 mm = 54 mm). This configuration suits applications where the probe tip must sit very close to the mounting surface. 

        The 330704-000-080-50-12-00 is designed for use with 5-meter Proximitor sensors (330780-50, -51, or -52). The 11 mm system outputs 3.94 V/mm (100 mV/mil) with a 4.0 mm (160 mil) linear range. The 330704-000-080-50-12-00 includes a locknut with pre-drilled safety wire holes as standard.
