Features:

  • Maintains Stable Signal Transmission Between the Proximity Probe and Monitoring System
  • Combines Durable Cable Construction with Effective Electromagnetic Interference Protection
  • Designed for Reliable Integration with Bently Nevada 3300 XL Proximity Probe Systems
The Bently Nevada 330730-040-01-05 functions as a proximity probe extension cable within the Bently Nevada 3300 XL vibration monitoring system, providing a stable electrical link between the proximity probe and the Proximitor sensor. It ensures accurate transmission of displacement and vibration signals from the probe to the monitoring module, supporting precise measurement of shaft position and machinery vibration. The cable is engineered to maintain consistent signal quality across the monitoring chain used in rotating equipment protection systems.

The Bently Nevada 330730-040-01-05 provides essential signal transmission functions for the 3300 XL monitoring system and is a critical component of the monitoring path, directly affecting accurate measurement of shaft vibration and displacement. One or more 330730-040-01-05 cables may be installed per machine depending on the number of measurement points and system configuration. The cable occupies a single connection location between the proximity probe and the Proximitor sensor, and is always routed to maintain proper alignment and signal integrity within the monitoring system.

For dual‑probe or multi‑cable monitoring applications, the 3300 XL system may require an additional 330730-040-01-05 extension cable installed to accommodate multiple measurement points or redundant signal paths. In addition to standard single‑probe operation, the redundant or multi‑cable configuration supports uninterrupted signal transmission. The system continually monitors the integrity of each cable and its connected probe. If a cable or probe connection is detected to be faulty or producing signals outside the expected range, the system automatically relies on the secondary or redundant cable to maintain accurate vibration and displacement measurement, while generating an alert or event in the monitoring system log.

The 330730-040-01-05 Bently Nevada high-performance cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer GE / Bently Nevada
  • Model 330730-040-01-05
  • Condition New Original ready stock
  • Product Family 330730-040-01-00,330730-040-00-05,330730-040-00-00
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Displacement and vibration measurement: The system outputs a voltage signal proportional to the distance from the probe end face to the measured metal surface (standard sensitivity is 3.94 V/mm or 100 mV/mil), used to monitor axial displacement (thrust) and radial vibration.
  • Mechanical Protection Applications:
  • Thrust Position Measurement: Prevents rotor-stator collision.
  • Differential Expansion Monitoring: Monitors the expansion difference between the rotor and the casing during turbine startup and shutdown.
  • Overspeed Protection: Can be used as a tachometer or keyphasor signal source, working in conjunction with the monitoring module to achieve overspeed protection.
  • System Stability and Interference Immunity:
  • RFI/EMI Immunity: Improved electromagnetic interference immunity design prevents false alarms or diagnostic errors caused by high-frequency radio signals in industrial environments.
  • Physical Protection: Equipped with FluidLoc sealing technology (to prevent liquid leakage) and electrostatic discharge (ESD) protection to ensure signal integrity in harsh environments.
  • Connector Installation: This cable uses ClickLoc gold connectors, which can be tightened simply by hand. A "click" indicates that it is locked in place; no wrench is needed, as excessive torque may damage the connector.
  • Connector Protector: The -01 option in the model number indicates that a connector protector is included. In humid, oily, or contaminated environments, ensure that the protector completely covers the connector to prevent signal attenuation or galvanic corrosion.
  • Complete Replacement Policy: All components of the 3300 XL 11mm system (probe, extension cable, preamplifier) ​​must be replaced with the purple-coded components of this series. It is strictly forbidden to mix them with older models or other series (such as the 8mm system).
  • Temperature Range: Operating and Storage Temperature: Standard range is -51°C to +177°C (-60°F to +350°F).
  • Accuracy Limits: To ensure optimal measurement accuracy (ISF within ±25%), it is recommended that the cable ambient temperature be maintained between -35°C and +65°C.
  • Humidity Tolerance: When the connector is protected by the protector (option -01 in the model number), it can withstand 100% condensation humidity, but it must not be immersed in liquid.
  • Chemical and Liquid Protection: Corrosion Resistance: The external stainless steel armor (AISI 302) provides excellent abrasion resistance, chemical resistance, and moisture protection. Leakage Prevention Design: Optional FluidLoctechnology (usually with different suffixes) prevents oil or other liquids from leaking into the machine through the cable interior.
Description
It plays an important role in transmitting and conditioning signals between vibration sensors and monitoring equipment, enabling accurate detection of mechanical conditions such as shaft vibration, displacement, and other dynamic parameters in rotating machinery. This capability allows operators to continuously monitor equipment health and respond quickly to abnormal operating conditions.

Constructed with a stainless steel housing body and engineered for long‑term durability in demanding industrial environments, the 24701‑33‑05‑00‑024‑04‑02 assembly includes a probe with connector protector and is configured with a 0.5 m probe cable length option. 

The probe penetration length of approximately 2.4 in (60 mm) ensures appropriate reach into the measurement area, while the housing provides threaded ports for conduit connections and optional standoff adapters for flexible installation.

The housing assembly is fully compatible with Bently Nevada’s 3300 series proximity transducers and condition monitoring systems, enabling seamless system integration. Its modular build and accessory features support reliable data collection for real‑time condition assessment and predictive maintenance strategies, enhancing equipment reliability and helping prevent unplanned downtime.
