Hardware Specifications

Rotor Dynamics and Gap Voltage Validation

Engineered to preserve signal integrity across harsh thermal gradients, the extension cable maintains precise eddy-current probe scaling and impedance matching within the 3300 XL measurement chain. Gap voltage validation targets a -10 VDC baseline when paired with standard Proximitor sensors and probes, ensuring accurate static shaft position and dynamic vibration feedback. Cross-talk suppression mechanisms within the coaxial shielding prevent electromagnetic interference injection along extended cable runs inside industrial turbine enclosures.

Mechanical Routing and Installation Guidelines

• Bend Radius Limits: Maintain a minimum bend radius of 25.4 mm during installation to prevent internal conductor deformation or armor crushing.
• Shield Grounding: Ensure continuous outer shield continuity from probe tip to Proximitor sensor housing, terminating secondary grounds only at approved panel locations.
• Thermal Isolation: Route the cable away from direct high-intensity thermal exhaust zones exceeding the 260 deg C rating limit, securing with high-temperature stainless steel clamps.
