This 3300 XL extension cable maintains strict impedance and capacitance matching across the high-frequency analog signal path. The cable is calibrated to preserve standard eddy-current probe scaling of 3.94 V/mm (100 mV/mil) when paired with an 11 mm proximity probe and the corresponding Proximitor sensor. During loop commissioning, field technicians must conduct a gap voltage validation to ensure the overall electrical system length matches the Proximitor’s tuning. Proper signal pathway impedance prevents radio-frequency interference and optimizes cross-talk suppression when multiple transducer systems are installed in close proximity near machine rotor dynamics components.
Q: Can this 330710 extension cable be coupled with an 8 mm proximity probe system?
A: No. The electrical capacitance and impedance characteristics of the 330710 cable are specifically tuned for 11 mm sensor systems. Intermixing with 8 mm components disrupts the calibration curve and introduces scale factor errors.
Q: What is the impact of altering the physical length of this extension cable in the field?
A: Cutting, splicing, or altering the length of the coaxial cable is strictly prohibited. The total electrical length is critical to the bridge circuit calibration; any physical length deviation changes the total system impedance and invalidates the linear range calibration.
