Eddy-Current Probe Scaling and Rotor Dynamics
The 330180-91-00 functions as an oscillator/demodulator, providing a linear output scaled at 7.87 mV/µm (200 mV/mil) relative to probe displacement. For precise rotor dynamics analysis, the sensor output must be verified via gap voltage validation at the terminal strip, targeting -10 VDC when the probe is positioned at the linear range midpoint. To maintain signal integrity, cross-talk suppression is achieved by observing minimum spacing requirements between adjacent probes, which prevents mutual RF interference. The integrated circuitry ensures a stable carrier signal essential for detecting sub-synchronous vibrations and shaft centerline deviations in rotating machinery.
Frequently Asked Questions
Q: Is the 330180-91-00 compatible with older 3300-series 8 mm probes?
A: Yes. The Proximitor Sensor is designed to accept 3300-series 5 mm, 3300 8 mm, and 3300 XL 8 mm proximity probes and their associated extension cables.
Q: Can this unit be mounted directly onto a DIN-rail?
A: Yes. The suffix 91 indicates a DIN mount configuration, allowing for secure attachment to standard industrial DIN-rail systems.
Field Installation Guidelines
- Secure the Proximitor to the DIN-rail, ensuring the mechanical interface is rigid to prevent vibration-induced signal noise.
- Connect the probe and extension cable, ensuring the coaxial connectors are hand-tightened until firm. Avoid over-tightening as this may damage the internal dielectric or connector threads.
- Route signal cabling through separate conduits from AC power or motor drive cabling to maintain the integrity of the high-frequency carrier signal.
- Verify the system common connection to ensure proper grounding of the signal shield.
- Perform a system startup check by measuring the output voltage at the monitor terminal block to confirm it matches the predicted gap voltage of -10 VDC for the installed probe depth.
