Gap Voltage Validation (-10 VDC targets)
The system utilizes an oscillator circuit to drive the transducer probe, generating a high-frequency electromagnetic field. To ensure output linearity, the system necessitates precise gap voltage validation during commissioning. The converter is designed to center its output around a nominal -10 VDC target, corresponding to the 1.5 mm center gap. Maintenance of this baseline is required for accurate tracking of shaft radial vibration and axial position. Deviations from the -10 VDC nominal gap voltage indicate potential installation misalignment, transducer saturation, or degradation of the conductive target surface, which must be addressed to prevent signal distortion.
Frequently Asked Questions
Q: Can this sensor be used on shafts with non-ferromagnetic materials?
A: The sensitivity and linearity are calibrated for electrically conducting steel. Usage on materials with different electrical conductivity or magnetic permeability will require a recalibration of the signal converter's sensitivity factor.
Q: How does shaft diameter affect the measurement accuracy?
A: A minimum shaft diameter of 25 mm is required to maintain the specified flux density. If the shaft diameter is smaller, the sensor output will exhibit non-linearities and reduced sensitivity compared to the factory calibration.
Field Installation Guidelines
- Ensure the mounting bracket is rigid to prevent mechanical resonances from influencing the transducer output.
- Install the probe at the 1.5 mm nominal gap using a non-conductive feeler gauge to avoid damaging the sensor tip.
- Verify that the shaft surface at the measurement location is free of scratches, burrs, or non-conductive coatings.
- Route signal cabling through grounded metallic conduit, keeping lines physically separated from high-current power cables to mitigate electromagnetic interference.
- Ground the system shield exclusively at the monitoring system (DCS/TSI) rack to prevent ground-loop current injection into the sensor signal.
