Eddy-Current Probe Scaling & Rotor Dynamics Interface

The module processes eddy-current probe signals with fixed scaling referenced to Proximitor conversion factors (typically 100 mV/mil or 200 mV/mil depending on configuration). Gap voltage validation is performed against a controlled negative bias window (commonly referenced system behavior near -10 VDC excitation domain at the probe-proximitor interface level).

Channel-to-channel isolation supports separation of radial vibration vectors, allowing independent X/Y rotor displacement reconstruction. Cross-talk suppression is implemented through internal analog filtering and grounded shielding architecture, minimizing phase coupling between adjacent probe channels under high shaft speed conditions.

Rotor dynamics interpretation is derived from buffered analog outputs, enabling external systems to reconstruct orbit plots, phase reference signals, and synchronous vibration components.

Frequently Asked Questions (FAQ)

Q: Can the module operate with a single proximity probe input instead of two channels?
A: Yes. Channel architecture supports single-channel operation, with the second channel left unassigned without affecting internal signal conditioning.

Q: Does the module support hot-swap in a live 3300 rack system?
A: Insertion and removal require system power isolation to avoid backplane transient disturbance; live hot-swap is not supported.

Q: What happens if a channel exceeds full-scale vibration input?
A: The signal path saturates at full-scale limit, and relay logic may trigger Danger output depending on configured setpoint thresholds.

Field Installation Guidelines

The module shall be installed in a valid slot of the 3300 rack system excluding slot positions 1 and 2. Backplane connector alignment must be verified prior to insertion to avoid pin damage.

Proximitor signal cables must maintain continuous shield integrity from probe head to monitor terminal, with single-point grounding at the rack end only. Cable routing shall avoid high-energy switching conductors and VFD output lines to minimize induced noise coupling.

Relay outputs must be wired as dry-contact circuits with external suppression provided at the load side when inductive devices are present.
