330130-040-03-05 Bently Nevada 4m Extension Cable

Product Overview

The 330130-040-03-05 is a premium, high-durability 4.0-meter industrial extension cable manufactured in the U.S.A. by Bently Nevada for their signature 3300 XL 8 mm proximity transducer system. Featuring an integrated stainless steel armored sheath and a total net assembly weight of 0.618 kg, this cable delivers rugged mechanical shielding and noise-immune signal transmission. It is precision-engineered to carry high-frequency vibration and position data from eddy current probes to Proximitor Sensors on heavy rotating machinery operating in hazardous, highly regulated environments.

Core Technical Advantages

• Interlocking Stainless Steel Armor: Engineered with a heavy-duty armored casing (103 g/m) that protects the delicate inner coaxial lines from crushing forces, sharp cuts, physical impacts, and abrasive plant wear.
• Double-Layer Joint Protection: Comes equipped with factory-installed rigid connector protectors alongside auxiliary silicone wrapping tape, ensuring the vital probe-to-cable electrical link stays securely insulated.
• Intrinsically Safe Design: Fully certified under global hazardous area standards, making it the industry standard for volatile processing zones where safety compliance is non-negotiable.

Technical Specifications

Installation & Maintenance Guide

• Turbine Oil Mitigation Notice: Every 3300 XL cable includes loose silicone tape for fast insulation. However, Bently Nevada explicitly warns against relying on silicone tape alone if the probe-to-cable connection is exposed to active turbine oil. Always deploy the integrated rigid connector protector sleeve in oil-rich areas.
• Loop Calibration Matching: To verify accuracy and interchangeability specs, the complete system loop must utilize matching 3300 XL 8 mm components, calibrated against an AISI 4140 steel target substrate under a -24 Vdc supply.
• Field Wiring Standards: Link terminal blocks using 3-conductor shielded triad field cables (0.2 to 1.5 mm² / 16 to 24 AWG). Limit the total distance between the Proximitor Sensor and the rack monitor to 305 meters (1,000 feet) to eliminate high-frequency signal roll-off.

Engineering Advantages

• Extreme Moisture Resistance: Built to withstand harsh plant environments, displaying less than a 3% change in Average Scale Factor (ASF) even when subjected to 93% relative humidity for 56 consecutive days per IEC 68-2-3 standards.
• Electrical Loop Stability: Strict manufacturing controls maintain an ultra-tight conductor core tolerance ($0.88 \pm 0.13\,\Omega$), ensuring highly predictable frequency response and minimal cross-talk across extended loops.

Technical FAQs

Q1: What benefit does the 03 option code provide over standard configurations?
A1: The 03 code signifies a heavy-duty interlocking stainless steel armor sheath providing 103 g/m structural strength, plus pre-fitted molded plastic boots that physically protect the connection point from dirt and stress.

Q2: Can I use this extension cable with older non-XL Bently Nevada sensors?
A2: While physical connections may thread together, optimal system accuracy and linear scale factors are only guaranteed when paired entirely with genuine 3300 XL 8 mm family components.

Q3: Does the 330130-040-03-05 model feature FluidLoc sealing?
A3: No. This specific code specifies standard armor without internal oil-blocking gels. If your application demands a fluid-tight block inside the cable core to stop oil migration out of the machine housing, please contact technical sales for alternative option codes.
