Bently Nevada  24765-02-01  | 3300 Proximity Transducer Extension Cable

Description

1. Product Title

Bently Nevada  24765-02-01  – 3300 Proximity Transducer Extension Cable

2. Product Overview

The 24765-02-01   is a high-precision extension cable manufactured by Bently Nevada (Baker Hughes) for use with their industry-standard 3300 series Proximity Transducer Systems. This component serves as the critical link between the proximity probe and the Proximitor® sensor, ensuring that the low-voltage eddy current signals are transmitted with minimal attenuation or phase shift.

Designed for demanding industrial environments, the 24765-02-01    is engineered to maintain a constant impedance and electrical length, which is vital for accurate vibration and position measurements. This specific configuration features a standard length and protective armor, solving the common industrial problem of signal degradation and physical cable damage in harsh machinery environments. It is an essential part of a complete machine protection system, ensuring that radial vibration, axial thrust, and speed measurements remain precise and reliable.

4. Key Features & Benefits

• Stainless Steel Armor: The <span style=”color: blue;”>24765-02-01</span> includes flexible stainless steel armor, providing superior mechanical protection against crushing, abrasion, and sharp edges in the machine train.
• Tight Electrical Tolerances: Specifically calibrated to match the 3300 Proximitor’s requirements, ensuring that the scale factor (typically 200 mV/mil) remains accurate across the entire linear range.
• Corrosion Resistance: The FEP jacket and gold-plated connectors offer excellent resistance to oil, chemicals, and moisture, preventing signal drift caused by environmental contamination.

5. Application Scenarios

• Steam Turbine Monitoring: Used to extend the reach of proximity probes mounted in the bearing housing to the Proximitor units located in a local junction box.
• Centrifugal Compressor Protection: Critical for transmitting high-frequency radial vibration data to the 3500 Monitoring System to detect shaft instability or oil whirl.
• Hydroelectric Generators: Employed in air-gap or shaft deflection monitoring where long cable runs are required through the stator frame.

6. Frequently Asked Questions (FAQ)

• Q: What is the primary function of the 24765-02-01</span>?
  • A: It provides a shielded, calibrated electrical path between a Bently Nevada proximity probe and a Proximitor sensor, allowing for remote mounting of the electronics.
• Q: Is 24765-02-01 compatible with legacy systems?
  • A: Yes, it is fully compatible with the 3300 series proximity systems. However, users must ensure the total system length (Probe + Extension Cable) matches the calibration of the Proximitor (typically 5 or 9 meters).
