Product Overview

The Bently Nevada 330130-070-03-00 serves as a vital high-fidelity transmission link within the 3300 XL 8mm Proximity Transducer System. Engineered to preserve signal purity over significant distances, this extension cable bridges the connection between the proximity probe and the Proximitor sensor. In critical rotating machinery—such as gas turbines, high-pressure compressors, and large induction motors—maintaining the integrity of eddy current signals is non-negotiable. The 330130 series employs advanced coaxial shielding to suppress electromagnetic interference (EMI), ensuring the Bently Nevada 3500 rack receives precise, jitter-free data for radial vibration and axial position monitoring. This cable facilitates the deterministic performance required for TSI (Turbine Supervisory Instrumentation) and high-speed machinery protection loops.

Model Configuration and Suffix Breakdown

The 330130-070-03-00 model string defines the mechanical and electrical characteristics required for specific site conditions. The -070 suffix designates a cable length of 7.0 meters (approximately 23.0 feet). This length is typically combined with a 2.0-meter probe to achieve a total system length of 9.0 meters, ensuring the Proximitor maintains its calibrated 200 mV/mil scale factor. The -03 suffix specifies the inclusion of stainless steel armor without a specialized protector, providing the physical ruggedness necessary to withstand mechanical abrasion in industrial conduits. The -00 suffix indicates standard agency approvals (ATEX/CSA), certifying the unit for use in globally recognized hazardous and non-hazardous areas.

Core Technical Parameters

Field Routing and Connectivity Protocols

Successful deployment of the 330130-070-03-00 requires strict adherence to system length matching. Field technicians must verify that the probe length plus this extension cable matches the Proximitor’s specific calibration (typically a 9.0m system). When routing the armored cable, maintain a minimum bend radius of 25.4 mm (1.0 inch) to avoid damaging the internal dielectric. Ensure all Click-Loc connectors are tightened finger-tight plus a slight 1/8 turn with a wrench to lock the gold-plated pins against mechanical vibration. For installations involving high-pressure oil environments, utilize the housing's internal seals to prevent oil wicking through the armor into terminal boxes.

Industrial Performance and Seamless Integration

The 3300 XL armored extension cable provides superior resilience in environments saturated with synthetic lubricants and high thermal gradients. It integrates flawlessly with Honeywell Experion PKS or Siemens SIMATIC S7 via the Bently Nevada 3500/42M monitor, ensuring that shaft centerline and orbit dynamics are transmitted with zero phase shift. The stainless steel armor prevents accidental crushing during routine maintenance, while the FEP jacket resists chemical degradation. This robust design complies with API 670 standards, offering the long-term stability required for offshore platforms and remote refineries where manual sensor recalibration is impractical.

Transducer Maintenance FAQs

Q1: Can I use this 7.0m cable with a 1.0m probe?

A1: No. This would result in an 8.0-meter system. Standard Proximitors are calibrated for either 5.0m or 9.0m. A mismatch will cause significant scale factor errors (mV/mil), leading to incorrect vibration readings in your monitor.

Q2: What are the benefits of the stainless steel armor (-03)?

A2: The armor protects the delicate coaxial core from physical impact, crushing, and sharp edges in the machine casing, significantly extending the service life of the transducer system in heavy industrial zones.

Q3: Is this cable resistant to moisture and oil?

A3: Yes. The internal cable uses FEP (Fluorinated Ethylene Propylene) insulation which is highly resistant to moisture wicking and chemical breakdown from common turbine oils.

Q4: How do I identify a "Not OK" signal at the monitor?

A4: Check the DC Gap Voltage. If the voltage is -24 VDC or 0 VDC, it usually indicates a short or open circuit in the extension cable or a disconnected Click-Loc junction.
