Bently Nevada 330190-085-00-05 3300 XL Standard Extension Cable

Configured for signal transmission between the proximity probe and Proximitor sensor in TSI monitoring platforms, the Bently Nevada 330190-085-00-05 (330130 Extension Cable) provides direct electrical execution for high-frequency vibration signal propagation.

Suffix Breakdown & Model Matrix

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The 330190-085-00-05 extension cable is an integral component of the 3300 XL transducer system, which is factory-calibrated for a specific total system length to maintain a nominal scale factor of 7.87 V/mm (200 mV/mil). Variations in total system impedance caused by cable length mismatches directly impact the linearity of the output signal and the accuracy of rotor dynamics measurements. In multi-channel monitoring applications, ensure that cabling for individual sensors is routed to maintain cross-talk suppression and prevent induced EMI from distorting the shaft vibration data being processed by the TSI instrumentation.

Frequently Asked Questions

Q: Can this 8.5 metre extension cable be shortened in the field?

A: No. The transducer system is calibrated as a matched set, including the probe, extension cable, and Proximitor sensor. Cutting or modifying the cable length alters the electrical impedance, which invalidates the calibration and induces measurement errors.

Q: Are the connectors compatible with earlier 3300 series components?

A: The ClickLoc connectors are specifically designed for the 3300 XL series. Intermixing with non-compatible series may lead to impedance mismatches or intermittent signal connections at the coupling points.

Field Installation Guidelines

• Mounting: Ensure the cable is secured at regular intervals to prevent mechanical strain on the connectors. Use non-conductive cable ties to avoid creating potential ground loops.
• Grounding: The cable shield must be maintained through the coupling to ensure electromagnetic immunity. Ensure no contact between the cable shield and the machine housing exists, except at the approved grounding point.
• Connector Integrity: Ensure that the ClickLoc mechanism is fully seated and locked. The connector must be clean and free of moisture or oil to prevent signal attenuation.
• Cable Routing: Route the coaxial cable through a dedicated metallic conduit, keeping the signal lines physically separated from high-voltage AC or motor power cables to minimize induced noise.
