In rotating machinery monitoring chains, the device output is directly influenced by rotordynamics excitation modes, including shaft imbalance and structural resonance coupling. Cross-axis mechanical coupling is limited through internal suspension geometry, maintaining transverse sensitivity below 10% at 100 Hz. Signal scaling behavior is independent of external excitation power, and output stability is governed by coil velocity response rather than displacement amplitude. This eliminates dependency on external excitation circuits typical of eddy-current probe scaling systems and avoids gap-voltage validation mechanisms such as -10 VDC reference loops used in proximity probe systems. Frequently Asked Questions Q1: Is the output signal active or externally powered?A1: The transducer is passive. Output voltage is generated by coil motion within a magnetic field and does not require excitation power. Q2: Can the unit be connected directly to a high-impedance input?A2: Yes. Recommended load is 10 kOhm or higher to maintain calibrated sensitivity response and prevent amplitude attenuation. Q3: What limits the low-frequency response boundary?A3: The low-frequency cutoff is defined by mechanical suspension characteristics and the 15 Hz configuration option (09 suffix), not by electronic filtering. Field Installation Guidelines Mount the transducer rigidly using the 1/4 in-20 UNC stud interface on a machined surface with verified flatness. Ensure full thread engagement of at least 5 turns minimum to prevent mechanical loosening under vibration load. Route signal wiring using shielded twisted pair conductors. The shield should be grounded at a single acquisition system end only to prevent ground loop current injection. Avoid routing signal lines parallel to high-current switching conductors or VFD output cables to minimize induced noise coupling. Install orientation according to expected vibration vector direction; although omnidirectional mounting is supported, axial alignment improves signal fidelity for dominant vibration modes.
