Hardware Specifications

Eddy‑Current Scaling and Gap‑Voltage Validation

3300 XL transducer systems operate on a standardized eddy‑current scaling curve that maintains linear displacement interpretation across the 8 mm sensing range. The proximitor drives the probe toward a nominal −10 VDC gap‑voltage target, ensuring stable rotor‑dynamic tracking and consistent phase response. The extended 5.0 m system length introduces additional coaxial impedance, and the factory‑matched cable ensures proper compensation without requiring recalibration. ClickLoc termination maintains shielding continuity, suppressing cross‑talk and micro‑motion noise in multi‑probe installations.

Frequently Asked Questions

Q: Can the transducer system be replaced while the proximitor remains energized? A: No. Replacement should occur only with the channel de‑energized to prevent transient gap‑voltage excursions.

Q: Does the 5.0 m cable length require proximitor recalibration? A: No. The cable length is factory‑matched. Non‑standard extensions alter impedance and shift the scaling curve.

Q: Does the absence of agency approvals affect installation? A: No. Electrical behavior is unchanged. Installation requirements follow standard 3300 XL practices.

Field Installation Guidelines

Maintain clean mounting surfaces to ensure stable mechanical seating. Terminate cable shielding at the proximitor end only to prevent ground‑loop formation. Avoid sharp cable bends that may alter coaxial impedance. Route cable away from high‑current conductors to reduce electromagnetic interference. Verify ClickLoc connector engagement before energizing the monitoring channel.
