Bently Nevada 1X35668 Proximity Probe Extension Cable

Bently Nevada 1X35668 Proximity Probe Extension Cable

Configured for high-frequency signal transmission in machinery monitoring networks, the Bently Nevada 1X35668 (1X35668 Extension Cable) provides direct physical/electrical execution. It functions within the 3300 XL NSv Proximity Transducer System to connect the proximity probe to the remote sensor evaluation electronics.

Hardware Specifications

Machinery Monitoring & TSI Characteristics

The extension cable acts as a matched impedance waveguide optimized for the 3300 XL NSv Proximity Transducer assembly. It transfers raw high-frequency RF signals without altering the electrical characteristics required for accurate eddy-current probe scaling. This precise capacitive and inductive impedance balance ensures accurate gap voltage validation, targeting standard -10 VDC operational metrics. The optimized internal shielding design minimizes high-frequency radiation, contributing directly to cross-talk suppression between neighboring transducers and allowing clean collection of high-resolution rotor dynamics.

Frequently Asked Questions

Q: Can this cable be shortened or spliced in the field if it is too long?

A: No. Proximity probe extension cables are calibrated to an exact electrical length matching specific inductance and capacitance values. Cutting, splicing, or changing the physical length of the cable will disrupt the circuit tuning, causing severe calibration shift and incorrect vibration data.

Q: What is the mechanical compatibility restriction for the 1X35668 cable?

A: This cable is engineered for the 3300 XL NSv system. It should not be interchanged with standard 3300 XL 5 mm or 8 mm proximity probe systems, as the different electrical properties will alter the transducer driver sensitivity and compromise system accuracy.

Field Installation Guidelines

• Connector Terminal Protection: Clean all coaxial connection terminals prior to mating. Ensure the male and female connectors are securely clicked and locked. Use specialized connector silicone insulation sleeves to prevent entry of water, lubricating oils, or process fluids.
• Minimum Bend Radius Constraints: Maintain a minimum structural bend radius of 25.4 mm during layout and installation. Sharp bends or pinching will deform the internal coaxial geometry, leading to signal degradation or physical failure under thermal expansion.
• Isolation and Conduit Routing: Route the extension cable inside dedicated flexible or rigid metal conduits. Ensure the conduit runs are isolated from lines carrying high-voltage AC or electrical noise from variable frequency drives (VFD) to prevent electromagnetic interference from inducing signal distortion.
