Description
The 330130-075-11-05 is a 7.5-meter (24.6 ft) standard extension cable used to electrically connect the 3300 XL proximity probe to the Proximitor® sensor in the Bently Nevada 3300 monitoring architecture.It belongs to the 3300 XL machinery condition monitoring family, which is widely used in industrial asset protection systems for precise measurement of shaft vibration, axial displacement, and position in fluid-film bearing machines.
Testing Procedure of 330130-075-11-05 Extension Cable
1️⃣ Visual and Mechanical Inspection
The initial step focuses on physical condition assessment:
- Inspect cable jacket for cuts, abrasions, deformation, or extrusion damage
- Verify connector integrity (no bent pins, corrosion, or contamination)
- Confirm correct part number marking: 330130-075-11-05
- Check shielding termination and grounding structure
Objective: Eliminate mechanical defects that may affect high-frequency signal transmission.
|
2️⃣ Continuity Test
Electrical continuity is verified using a multimeter or cable tester:
- Confirm end-to-end continuity of the center conductor
- Verify continuity of the shielding conductor
- Ensure absence of open circuits
- Ensure no unintended short circuits between conductor and shield
Acceptance criterion: Near-zero resistance for conductors; no leakage paths.
|
3️⃣ Insulation Resistance Test
A megohmmeter is used to evaluate dielectric integrity:
- Apply DC test voltage (typically 250–500 V)
- Measure resistance between center conductor and shield
Acceptance criterion: High insulation resistance (typically in MΩ to GΩ range), indicating no leakage or insulation breakdown.
|
4️⃣ Capacitance and Impedance Verification
This step ensures system-level compatibility with the 3300 XL proximity system:
- Measure cable capacitance (pF/m)
- Verify nominal system impedance (75 Ω design architecture)
- Evaluate signal attenuation consistency
Objective: Maintain calibration integrity between probe, extension cable, and Proximitor sensor.
|
5️⃣ EMI and Shielding Effectiveness Test
Electromagnetic compatibility is evaluated under simulated industrial interference:
- Inject controlled electromagnetic noise (EMI stress conditions)
- Observe noise coupling into signal path
- Evaluate shielding effectiveness performance
Acceptance criterion: No significant signal distortion or noise-induced drift.
