Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The 3300 XL extension cable is specifically engineered to maintain signal integrity in rotor dynamics applications. It utilizes precise eddy-current probe scaling properties to ensure that the total system length remains calibrated, supporting the -10 VDC nominal gap voltage required for accurate vibration monitoring. The cable design features advanced cross-talk suppression to mitigate electromagnetic interference between adjacent signal paths in high-density installations. Its compatibility ensures seamless integration with 3300 series components, eliminating the need for system re-calibration when replacing individual probes or sensors.

Frequently Asked Questions

Q: Does the 7-meter length affect the Proximitor sensor calibration?

A: No, the 3300 XL system is designed for total system length interchangeability; the Proximitor sensor is calibrated to account for the specific length of the extension cable, provided the system matches the designated length rating.

Q: Are these cables compatible with older, non-XL 3300 series hardware?

A: Yes, these components are fully backward compatible with legacy 3300 series 5 mm and 8 mm transducer systems, allowing for direct replacement in existing installations.

Field Installation Guidelines

• Connector Protection: Use the included connector protectors during cable pulling to prevent damage to the delicate coaxial interfaces and to prevent ingress of dirt or moisture.
• Routing Constraints: Avoid bending the coaxial cable at a radius smaller than the manufacturer's specified minimum to prevent deformation of the internal dielectric, which can cause signal impedance changes.
• Shielding Integrity: Ensure the coaxial shield remains continuous and is not grounded at any point other than the designated monitor backplane ground to prevent ground loop noise.
• Cable Splicing: Do not attempt to splice or shorten the cable length in the field, as this will alter the electrical capacitance and invalidate the API 670 system accuracy compliance.
