Features:

  • Link Between the Proximity Probe and the 3300 XL Proximitor Sensor
  • Provides 8.5-Meter Electrical Length with Factory-Calibrated Signal Integrity
  • Compatible with the 3300 XL 8mm Eddy Current Proximity Transducer System
The 129957-085-310-05 functions as the 3300 XL 8mm Extension Cable within the Bently Nevada proximity sensor system, establishing the essential coaxial connection between the probe tip and the Proximitor sensor. It maintains the precisely matched electrical length required for accurate eddy current signal transmission, ensuring that vibration and position data remain uncompromised across the full 8.5-meter span. The 129957-085-310-05 incorporates PFA insulation and a compatible locking connector design, allowing it to withstand oil immersion, moisture exposure, and chemical contaminants commonly encountered in heavy industrial environments.

The 129957-085-310-05 delivers the critical signal pathway for the entire transducer assembly, and is a vital element of the measurement chain, directly influencing the precision and stability of the overall monitoring system. One 129957-085-310-05 extension cable is required per probe installation where the standard integral cable length is insufficient to reach the Proximitor mounting location. The 129957-085-310-05 occupies no rack slot, as it is a field-installed cabling component routed externally between the machine casing and the sensor interface.

For installations requiring extended reach, the 129957-085-310-05 provides a factory-calibrated 8.5-meter electrical length that eliminates the need for field splicing or custom cable fabrication. In addition to standard single-cable operation, the 129957-085-310-05 maintains the characteristic impedance and capacitance specifications required by the 3300 XL system. Using this method, the extension cable preserves the factory-matched electrical properties between the probe, cable, and Proximitor. If the system detects any degradation in signal quality due to cable damage or connector corrosion, the 129957-085-310-05 can be replaced independently without requiring recalibration of the entire transducer assembly.

The 129957-085-310-05 Bently Nevada Extension cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Bently Nevada 129957-085-310-05 is a specialized 8.5-meter extension cable engineered for the 3300 XL 8mm Proximity Transducer System. As a precision-calibrated component, the 129957-085-310-05 functions as the essential electrical link between a proximity probe and a Proximitor sensor. This specific 129957-085-310-05 model features high-quality coaxial construction with PFA insulation, ensuring that the 129957-085-310-05 maintains signal integrity while resisting environmental hazards like oil, moisture, and chemical exposure in demanding industrial settings.

The 129957-085-310-05 is specifically designed to handle the challenge of signal attenuation and impedance mismatching in large-scale rotating machinery. In many industrial layouts, the distance between the monitoring point on a turbine or compressor and the control cabinet is significant. The 129957-085-310-05 solves this problem by providing a standardized 8.5-meter electrical length that allows for flexible sensor placement without sacrificing the accuracy of vibration or position data. By using the 129957-085-310-05, engineers ensure that the proximity system remains perfectly tuned for measuring critical parameters like radial vibration and axial thrust.

In practical application scenarios, the 129957-085-310-05 is indispensable for monitoring high-speed centrifugal compressors and steam turbines where space constraints require the Proximitor to be mounted away from the machine casing. The 129957-085-310-05 solves the issue of mechanical wear and cable degradation in high-vibration zones through its robust connector design and protective shielding. By integrating the 129957-085-310-05 into a condition monitoring strategy, plants can prevent catastrophic machine failure through reliable, real-time data transmission provided by this dedicated 129957-085-310-05 extension cable.
