330930-065-05-00 New Bently Nevada Armored Extension Cable 6.5m

Product Overview

The Bently Nevada 330930-065-05-00 is an armored 75 Ω coaxial signal transmission lead designed specifically for the 3300 NSv Series proximity transducer system. Functioning as the vital link between a 3300 NSv probe and a Proximitor Sensor, this 6.5-meter cable features stainless steel flexible armor and pre-installed connector protectors. It preserves signal integrity and precise scale factor calibration across high-vibration, tight-clearance industrial environments.

Technical Specifications Matrix

Variant Comparison & Engineering Recommendations

Selecting the appropriate jacket and armor option within the 3300 NSv Series cable family depends directly on field exposure to fluids and mechanical abrasion:

• Target Unit: 330930-065-05-00 features bare AISI 302 stainless steel armor for maximum crush resistance in dry, high-temperature machinery housings.
• Alternative Unit: Compare with 330930-065-11-00. That model adds a protective FEP outer jacket over the stainless steel armor for chemical and fluid isolation.

Technical Selection Tip: Specify 330930-065-05-00 for internal turbine bearing housings where bare armor tolerates extreme heat without off-gassing. Choose 330930-065-11-00 when routing across open plant floors where caustic washdowns or synthetic lube oils could breach unjacketed metallic armor.

Target Applications & Machinery Diagnostics Support

• Bridging 3300 NSv proximity probes to Proximitor Sensors on small-shaft turbomachinery
• Radial vibration and axial thrust measurement in confined bearing housings with narrow side clearances
• Phase reference Keyphasor signal transmission on high-speed compressor rotors
• Protecting raw high-frequency vibration signals against severe plant electromagnetic noise (EMI)
• Enabling continuous gap voltage tracking for journal bearing oil film degradation diagnostics

Global PLC Spare HUB Insights & Field Experience

In eddy current transducer systems, system tuning depends on total electrical length. The sum of probe length plus extension cable length must strictly equal the calibrated total length of the Proximitor Sensor (typically 5.0m or 7.0m system totals). In field service calls, our technicians frequently diagnose scale factor errors (e.g., deviation from 200 mV/mil) caused by pairing a 1.0-meter probe with a 6.5-meter cable on a 5.0-meter Proximitor Sensor. When installing the 330930-065-05-00, ensure it is paired strictly with a 0.5-meter 3300 NSv probe to achieve a precise 7.0-meter system balance, and always snap the connector protector shut to lock out conductive debris.

Frequently Asked Questions (FAQ)

Q1: Why is matching total system length critical for the 330930-065-05-00 cable?

A1: Eddy current Proximitor Sensors are tuned to a specific total system capacitance. Mismatched cable lengths shift the resonant frequency, throwing off voltage output linearity and scale factor accuracy.

Q2: What probe length must be paired with this 6.5-meter extension cable?

A2: A 6.5-meter cable must be paired with a 0.5-meter probe to form a complete 7.0-meter system calibrated to a 7.0-meter 3300 NSv Proximitor Sensor.

Q3: What purpose does the connector protector serve on option 05?

A3: The rubberized connector protector insulates delicate miniature ClickLoc coaxial junctions from oil mist, moisture, and shorting against machine casing grounds.

Q4: Can this bare stainless steel armor version be pulled through tight conduit runs?

A4: Yes. The AISI 302 stainless steel armor provides high flexible tensile strength (up to 220 N pull force), protecting internal coaxial insulation during difficult conduit pulls.

Q5: What is the recommended field wiring specification from the Proximitor to the monitoring rack?

A5: Bently Nevada recommends using 3-conductor shielded triad cable (16 to 24 AWG) up to a maximum distance of 305 meters (1,000 feet).
