Description

The Bently Nevada 330130-085-00-05, also cataloged as the 330130 Standard Extension Cable, operates as a dedicated hardware component for eddy-current signal transmission within 3300 XL Proximity Transducer System networks.

Hardware Specifications

Machinery Monitoring & TSI Characteristics

This triaxial cable actively manages eddy-current probe scaling because it preserves the strict impedance integrity of high-frequency RF signals between the probe tip and the Proximitor sensor. Consequently, stable electrical properties ensure precise gap voltage validation across the nominal -10 VDC targets required for linear displacement calibration. Because the cable design suppresses cross-talk and minimizes electrical attenuation, the component transmits clear rotor dynamics data, including static axial position and dynamic radial vibration measurements, without introducing phase error or calibration drift.

Frequently Asked Questions

Q: Does this extension cable support hot-swapping while the Proximitor sensor is powered?

A: Yes. Technicians can physically disconnect and reconnect the passive cable without disrupting the transducer electronics, provided they verify the surrounding environment as non-hazardous.

Q: What is the maximum mechanical torque allowed for the ClickLoc connectors?

A: Technicians must finger-tighten ClickLoc connectors until an audible click confirms engagement. Therefore, operators must avoid mechanical tools, as the hardware limits torque to 0.565 N m.

Q: Can this cable be used with non-XL 3300 series proximity probes?

A: Yes. The cable maintains backward compatibility with standard non-XL 3300 series 5 mm and 8 mm systems, though users must ensure the combined length matches the total system calibration length of 9.0 m when pairing an 8.5 m cable with a 0.5 m probe.

Field Installation Guidelines

• Shielding and Grounding: Terminate the coaxial outer shield only at the Proximitor sensor ground point. Do not ground the cable shield at the machine casing or intermediate junction boxes, because doing so creates ground loop interference.
• Routing Constraints: Avoid routing the triaxial cable parallel to high-voltage AC power lines. Instead, cross power conduits at right angles to minimize electromagnetic cross-talk.
• Bend Radius Limits: Maintain a minimum physical bend radius of 25.4 mm during installation. Tight bends degrade the internal FEP insulation and alter the core conductor properties.
