Hardware Specifications

Rotor Dynamics & Signal Integrity

This extension cable is engineered to maintain system-wide impedance integrity essential for 3300 XL transducer systems. The cable characteristics ensure minimal signal attenuation for eddy-current probe scaling, allowing for accurate gap voltage validation at the Proximitor sensor interface. The construction provides effective cross-talk suppression by utilizing low-capacitance coaxial geometry, maintaining the signal-to-noise ratio required for high-fidelity rotor dynamics analysis and radial vibration monitoring.

Ordering Info

• 1 x 330130-075-01-07 Extension Cable

• 1 x Pair of Connector Protectors (Pre-installed)

• 1 x Technical Instruction Sheet

Field Deployment Directives

• Routing: Install within dedicated metallic conduit to provide shielding against electromagnetic interference.

• Bend Radius: Maintain a minimum bend radius of 60 mm to prevent internal insulation deformation.

• Connection: Ensure both male and female connectors are clean and dry; tighten only by hand until the protective boot seals fully.

• Grounding: The cable shield must only be grounded at the Proximitor end to prevent ground loop currents.

Technical Inquiries

• Q: Is this cable compatible with 3300 series probes?

  A: No, the 3300 XL system requires matched 3300 XL probes to maintain the 75 Ohm system impedance.

• Q: Can the cable be spliced if damaged?

  A: No, splicing alters the characteristic impedance, leading to signal degradation and inaccurate vibration data.

• Q: What is the purpose of the connector protector?

  A: It provides a sealed environment against oxidation and moisture ingress for the coaxial contact surfaces.

• Q: Does length affect the output signal?

  A: The system is calibrated for a specific total length; changing the cable length requires recalibration of the Proximitor.

• Q: How is the cable shielded?

  A: It utilizes a braided outer conductor as a primary shield against external EMI.

• Q: What is the maximum pull force?

  A: Do not exceed 200 N of pull force to avoid internal conductor stretching.

• Q: Can this cable be used in vacuum applications?

  A: Yes, the cable materials are suitable for standard industrial vacuum chamber deployments.

• Q: How to check for cable continuity?

  A: Perform a resistance check between the center conductor and the shield using a digital multimeter on a non-powered system.
