Technical Physical Properties

Eddy-Current Transducer Performance

The 330130 series cable maintains system-wide signal integrity by ensuring constant impedance across the transducer loop. When calibrated with 3300 XL probes, the system achieves a linear output of 7.87 V per mm (200 mV/mil). The extension cable construction includes a fluoro-ethylenepropylene (FEP) jacket to prevent degradation of the electrical signal path due to chemical exposure. Proper gap voltage validation is required during installation; for a 3300 XL system, the target gap voltage at the probe tip remains -10 VDC when centered within the linear range. Cross-talk suppression is maintained by the high-frequency shielding integrated within the triaxial cable geometry.

Cable Installation Procedures

• Cable Routing: Maintain a minimum bend radius of 25 mm to prevent insulation fracture or internal conductor fatigue.

• Connector Engagement: Ensure the ClickLoc connectors are fully locked; the locking mechanism must provide a tactile click to confirm a sealed, low-resistance connection.

• Protection: Use conduit or armor for cable runs exceeding 3 meters to mitigate mechanical stress and electromagnetic interference.

• Grounding: Avoid grounding the shield at both ends to prevent ground loop noise; ensure the shield is continuous through the connector interface.

Frequently Asked Questions

• Can I use this cable with non-XL 3300 series probes?

  No. 3300 XL extension cables are calibrated specifically for the 3300 XL system impedance requirements and will introduce signal inaccuracies if mixed with older 3300 probe series.

• What happens if the cable is cut and spliced?

  Splicing violates the system impedance and shielding continuity. This will alter the scale factor and introduce noise, leading to incorrect rotor vibration measurements.

• Does the CN suffix affect electrical performance?

  No. The CN suffix denotes regulatory compliance for regional logistics and does not change the physical construction, shielding, or electrical specifications of the cable.

• How do I test for cable continuity?

  Use a digital multimeter in resistance mode. Measure core-to-core and core-to-shield resistance; however, verify against Bently Nevada technical drawings for exact target resistance values.

• Can this cable be submerged in oil?

  Yes. The FEP jacket is rated for total immersion in synthetic and petroleum-based lubricating oils typically found in rotating machinery environments.

• Is the connector waterproof?

  The ClickLoc connector is designed to be oil-tight and moisture-resistant when properly latched, but it is not intended for high-pressure subsea immersion.

• What is the impact of cable length on output?

  The 3300 XL system is designed as a calibrated whole (Probe + Extension Cable + Proximitor). Changing the extension cable length requires recalibration of the Proximitor sensor.

• Can this cable be used in hazardous areas?

  Yes, provided the entire transducer system (Probe, Cable, Proximitor) is installed within an intrinsically safe circuit as defined by regional Ex certifications.
