Hardware Specifications

Eddy-Current Probe Scaling and Signal Integrity

The 330130 extension cable is a component of the 3300 XL proximity transducer system. System performance is dependent on maintaining precise impedance characteristics across the probe, extension cable, and Proximitor interface. To ensure accurate rotor dynamics data, technicians must perform a gap voltage validation, targeting -10 VDC at the linear range center. The cable design incorporates integrated shielding to provide cross-talk suppression, minimizing electrical noise interference in high-density sensor installations. Any modification to the total system length requires recalibration of the monitoring module to account for signal attenuation.

Frequently Asked Questions

Q: Can the cable be trimmed to fit shorter installation requirements?

A: No. The electrical characteristics, including capacitance and impedance, are factory-tuned to the specific length. Altering the cable length will invalidate the system calibration and introduce measurement errors.

Q: What is the maximum tightening torque for the connector interface?

A: Connectors must be finger-tightened only. The use of pliers or torque wrenches can damage the FEP-insulated coaxial structure or deform the connector pins, leading to signal discontinuity.

Field Installation Guidelines

1. Ensure the installation area is free of conductive dust or fluids that could compromise the connector integrity.
2. Route the cable through dedicated, non-metallic or grounded conduit to maintain signal shielding and prevent mechanical abrasion.
3. Install the included connector protectors prior to pulling the cable through conduits to prevent moisture and particulate ingress.
4. Verify that the combined length of the probe and extension cable matches the configuration settings programmed in the Bently Nevada monitoring hardware.
5. Secure the cable with appropriate strain relief to prevent mechanical stress on the connection points due to machine-induced vibration.
