Hardware Specifications

Mechanical Monitoring & TSI Integration

The 330877 extension cable is designed to support the specific eddy-current probe scaling of the 3300 XL system. Its PFA insulation and FluidLoc construction are designed to mitigate ingress in harsh environments, ensuring that signal transmission remains stable for rotor dynamics analysis. To ensure accurate gap voltage validation at the sensor output, the cable must be installed to prevent excessive bending radii which could alter the characteristic impedance. Cross-talk suppression is maintained through the triaxial cable geometry, effectively shielding the high-frequency carrier signal from external electromagnetic interference present in machine trains.

Frequently Asked Questions

Q: Can this cable be shortened in the field?

A: No. Shortening the cable alters the system-tuned length, which directly impacts the Proximitor Sensor calibration and linearity. Any modification to the cable length will necessitate recalibration of the entire transducer system.

Q: How should the cable be protected during routing?

A: The FluidLoc armor provides mechanical protection against fluids and abrasion. Use approved cable clamps for routing and ensure the minimum bend radius is respected to prevent damage to the internal conductors.

Field Installation Guidelines

1. Route the extension cable through rigid conduit where possible to prevent physical damage.
2. Ensure that the connector interfaces are clean and free of moisture before mating; use a protective sealant tape if installing in humid or wash-down environments.
3. Tighten the coaxial connectors manually; avoid the use of pliers to prevent crushing the connector housing or damaging the internal pin.
4. Secure the cable with supports every 0.5 metres to prevent vibration-induced fatigue at the connection points.
5. Verify cable continuity with a multimeter to ensure no open or short circuits exist in the conductor or shield before finalizing the installation.
