Information

Overview Manuals Common Applications Product Precautions
The 129715-138-40-05-05 is the part number of a 3300 XL proximity sensor from Bentley Nevada.It is the premier choice for international EPC contractors, multi-national power generation facilities, and global system integrators who require strict hazard-zone compliance across different continents without replacing hardware.
    • Massive Range Demodulation
    • 4.0m Pre-Calibrated Impedance
    • 50ΩRobust Transmission
The 3300 XL Large Linear Range System (including 11 mm and 25 mm options supported by Model 129715) delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL transducer systems fully comply with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL proximity transducer systems provide this elite level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench-calibrate individual components. Each 3300 XL Transducer System component is backward-compatible and interchangeable with other legacy non-XL series transducer system components, maximizing the lifespan of your existing monitoring infrastructure.

Pulp & Paper
Mounts in localized instrument racks to monitor the gear alignment and shaft movement of heavy wood pulp refiners against constant high-pressure washdowns.

Liquefied Natural Gas
Works within intrinsically safe loops to monitor the shaft alignment and expansion of cryogenic boil-off gas (BOG) compressors under hazardous atmospheres.

Thermal Power
Conditions long-range proximity signals to track the macro-level differential expansion (DE) of large steam turbine rotors during rapid startups, preventing blade-to-casing collisions.

Nuclear Power
Provides highly reliable axial thrust position data for high-capacity cooling water circulation pumps, meeting global multi-agency safety compliance standards.

Iron & Steel
Processes proximity probe signals from giant blast furnace blowers, resisting extreme localized radiant heat and severe external electromagnetic noise.

 When using the 129715-138-40-05-05 Proximitor, always follow these critical guidelines. Completely power off the system before wiring and use ESD protection to prevent chip burnout. Tighten the coaxial ClickLoc connector to a maximum torque of 0.565 N·m and seal it with oil-resistant heat-shrink tubing to block moisture and oil mist. Lastly, this unit is permanently calibrated for an exact 4.0-meter total cable length (-40 option) and must never be cross-mixed, with the loop shield grounded at the monitor rack end only to avoid severe signal noise.

FAQ View All FAQ

  • What is 129715-138-40-05-05?
    It is an industrial sensor component, specifically a Proximitor Sensor belonging to the Bently Nevada 3300 XL 8mm Proximity Transducer System.
  • Which brand manufactures 129715-138-40-05-05?
    This product is manufactured by Bently Nevada , a specialized condition monitoring brand under Baker Hughes.
  • What is the working principle of 129715-138-40-05-05?
    It operates on the Eddy Current principle. The Proximitor sensor supplies a high-frequency radio frequency (RF) signal to the probe, creating eddy currents on the target metal surface. Changes in the gap change the RF impedance, which the sensor demodulates into a voltage output.
  • What is the core function of 129715-138-40-05-05?
    Its core function is to provide a DC/AC voltage output that is directly proportional to the physical distance (gap) between the probe tip and the observed conductive target. This allows for precise static displacement and dynamic vibration measurements.
  • Why must large machinery use 129715-138-40-05-05?
    The raw signal coming directly from a probe tip is too weak and highly susceptible to noise. The Proximitor sensor amplifies and converts this impedance change into a low-impedance voltage signal, allowing error-free transmission over long distances to the control room.
