Description
Bently Nevada 330130‑045‑00‑05 — 3300‑XL Probe Extension Cable
Product Overview
The 330130‑045‑00‑05 is a Microdot‑type extension cable from Bently Nevada 3300‑XL 8 mm proximity transducer system. It interconnects proximity probe and proximitor module to extend signal transmission distance. Compliant with API 670, this coaxial extension cable is a critical component for radial vibration, thrust position and Keyphasor measurement loops in turbomachinery protection and predictive condition‑monitoring systems.
Critical Compatibility Warning
- Designed exclusively for 3300‑XL 8 mm proximity probes with Microdot connector and matching 330180‑xx‑00 proximitor modules.
- Not compatible with 11 mm probe series or NSv transducer series.
- Sum of probe integral pigtail length plus this extension cable length must equal the exact total system cable length specified for the proximitor. Incorrect total cable length will cause scale‑factor deviation and measurement error.
- Works with 3500/42M, 3300 series monitor racks for alarm, trip and trending functions.

- Dual‑ended Microdot male‑to‑male connectors: Direct plug‑and‑play connection between probe and additional extension cables or proximitor.
- Heavy‑duty full‑shield coaxial construction: Excellent EMI rejection, minimizes external electrical interference for vibration and thrust signal transmission.
- Broad operating temperature range: Tolerates oil‑mist and high‑temperature environment inside turbomachinery cabinets and field junction boxes.
- Intrinsic‑safety certified: Suitable for installation in hazardous classified zones when assembled within complete certified 3300‑XL transducer loop.
- Modular expandability: Multiple extension cables can be cascaded to achieve required total system length.
Typical Application Scenarios
- Turbine and centrifugal compressor vibration / thrust‑protection loops requiring intermediate signal extension
- Field installations where proximitor module is located far away from machine casing mounted proximity probes

Installation and Configuration Guide
Warning: Installation must be performed by qualified instrumentation technicians. Always refer to original Bently Nevada 3300‑XL official manual as primary reference document.
- Mechanical & Cabling Installation
- Route the coaxial extension cable separately from high‑power AC cables, contactor and VFD wiring to reduce EMI interference.
- Observe minimum cable bending radius; do not apply sharp kinks, pinch or crush the coaxial cable.
- Secure cable with proper clamps; avoid tension stress applied directly to Microdot connector joints.
- Connector Mating & Torque Control
- Align Microdot pin positions before insertion; do not force connector mating.
- Tighten Microdot connector to manufacturer‑specified torque value. Over‑torque will damage pins; under‑torque causes intermittent signal faults.
- Never connect or disconnect transducer cables while proximitor power supply is active.
- System Total‑Length Validation
- Calculate total transducer cable length = probe integral pigtail length + extension cable(s) length.
- Confirm calculated total length matches the rated cable length of installed proximitor. Mismatch will produce incorrect scale‑factor output.
- System Commissioning Test
- Complete full transducer loop wiring, power on proximitor.
- Perform static gap calibration test with calibration fixture, verify output voltage and scale‑factor performance.
- Confirm Not‑OK fault status is cleared after correct wiring.
- Maintenance & Troubleshooting
- Inspect Microdot connectors for dirt, corrosion and loose connection during machinery turnaround.
- Check cable jacket for abrasion, oil erosion and mechanical damage.
- Signal drift or intermittent Not‑OK alarms may indicate defective extension cable or poor Microdot contact. Replace complete cable assembly; field repair of coaxial cable is not recommended.
- Hazardous‑Area Installation Notes
- For ATEX / IECEx classified‑zone deployment, strictly follow 3300‑XL intrinsic‑safety requirements covering cable specification, shielding grounding and chassis‑grounding rules.
Supplementary Remark
330130‑045‑00‑05 is a 4.5 m double‑ended Microdot‑to‑Microdot shielded coaxial extension cable for Bently Nevada 3300‑XL 8 mm proximity transducer system. Always verify the sum of probe pigtail plus extension cable matches proximitor total cable rating prior to commissioning. Prior to site installation, cross‑check part‑number, cable length, connector type and hazardous‑area certification against project BOM and mechanical drawings.
